Should You Use Wood Chips or Straw for Deep Mulch Gardening in No-Till? (Wood Chips vs. Straw)

The shift from tractor-driven tillage to regenerative, no-till bed management represents a fundamental turning point in soil stewardship. For generations, backyard rototillers and mechanical tractor discs were considered indispensable tools for weed suppression and seedbed preparation. However, that constant churning comes with a severe ecological cost: it fractures natural soil aggregates, shatters delicate mycorrhizal fungal networks, oxidizes valuable organic matter into atmospheric carbon dioxide, and dredges up thousands of dormant weed seeds from the soil seed bank.

When we transitioned our Alabama market farm to permanent no-till raised beds back in 2008, breaking free from the rototiller was our top priority. We had spent years fighting hardpan compaction, summer drought crusting, and unending waves of pigweed and crabgrass. We needed a biological shield that could insulate our soil from 95°F summer heatwaves, lock in soil moisture, and nourish biological life from the surface downward.

That biological shield is deep mulch gardening.

Whether you are managing a quarter-acre commercial market plot, tending community garden rows, or optimizing backyard raised beds, mastering the selection and application of deep organic mulches is one of the most effective skills you can develop. Yet among the diverse mulching materials available to growers, two dominate practical discussions: wood chips and cereal straw.

While both materials cover the ground, their physical densities, carbon structures, decomposition pathways, and horticultural applications are fundamentally different. Spreading the wrong mulch on the wrong crop can delay spring soil warm-up, invite destructive rodent populations, introduce persistent herbicide damage, or complicate direct seeding.

This guide examines the biological science, thermodynamic behavior, and practical economics of wood chips versus straw, giving you a clear field manual for your growing space.

1. Core Ecological Functions of Deep Mulch Systems

Before comparing wood chips directly against straw, it helps to review what an undisturbed, deep mulch layer accomplishes physically, chemically, and biologically within the soil profile.

The Deep Mulch Soil Interface
=============================================================================
[ Air Layer ]        Solar Radiation & Wind (Drying Forces Checked)
-----------------------------------------------------------------------------
[ Mulch Canopy ]     4" - 8" Coarse Organic Blanket (Straw or Wood Chips)
                     * Blocks 100% of Photosynthetic Light (Suppresses Weeds)
                     * Buffers Thermal Extremes (Keeps Soil 15°F - 25°F Cooler)
-----------------------------------------------------------------------------
[ Micro-Interface ]  Active Decomposer Zone (Fungal Hyphae & Aerobic Bacteria)
                     * High Moisture, Humic Acid Polymerization
-----------------------------------------------------------------------------
[ Native Topsoil ]   Permanent Undisturbed Aggregates, Earthworm Macropores,
                     Living Roots, Retained Capillary Moisture
=============================================================================

Moisture Retention and Capillary Breakage

Bare garden soil functions like an open wick. As sunlight warms bare ground and wind sweeps across the surface, capillary action draws water upward from lower subsoil horizons, rapidly vaporizing it into the atmosphere. Within forty-eight hours of a heavy rainfall, unmulched topsoil can bake into a cracked, impermeable crust.

A thick layer of organic mulch creates an absolute capillary break. Because the coarse particles of straw or wood chips contain wide, irregular air pockets, capillary water cannot travel upward through the mulch layer. Moisture remains locked in the upper two to four inches of topsoil where young feeder roots concentrate. In our hot Alabama summers, beds blanketed with six inches of settled straw require less than one-third of the supplemental irrigation demanded by bare-soil beds.

Thermal Buffering and Soil Temperature Regulation

Soil biology has strict thermal thresholds. Most beneficial soil bacteria, mycorrhizal fungi, and earthworms function at peak metabolic efficiency when soil temperatures remain between 65°F and 78°F (18°C to 25°C).

When bare soil absorbs direct solar radiation in midsummer, surface temperatures routinely exceed 115°F to 130°F (46°C to 54°C). Under those extreme conditions:

• Fine root hairs desiccate and die back.
• Earthworms burrow deep into subsoil layers and enter estivation.
• Nitrogen-fixing bacteria and mycorrhizae cease nutrient exchange.
• Fruiting crops suffer physiological heat stress, triggering blossom drop in tomatoes, peppers, and eggplants.

A four- to eight-inch layer of organic mulch functions like residential attic insulation. By reflecting a portion of solar radiation and absorbing the rest within its porous bulk, mulch keeps midsummer root-zone temperatures ten to twenty degrees cooler than ambient air. In winter, that same insulation traps geothermal warmth, shielding overwintered root vegetables and soil microbes from damaging freeze-thaw cycles.

Photoblastic Weed Smothering

The vast majority of agricultural weed seeds—including pigweed (Amaranthus), lamb's quarters (Chenopodium album), and purslane (Portulaca oleracea)—are photoblastic, meaning they require exposure to specific wavelengths of sunlight to trigger germination.

When you till the soil, you pull buried weed seeds into the light. A deep mulch blanket does the opposite: it creates total darkness across the native soil seed bank. Weed seeds remain dormant beneath the organic blanket. For aggressive perennial weeds that manage to push shoots upward through the mulch, the lack of light forces them to burn their stored root starches developing thin, pale stems. By the time their shoots emerge, their root anchors are weak and easily pulled by hand.

Humus Formation and Cation Exchange Capacity

Unlike synthetic black plastic films or woven polypropylene landscape fabric, organic mulches are active biological food sources. Macro-arthropods, earthworms, fungi, and bacteria steadily consume the lower surface of the mulch where it contacts damp earth.

As that organic matter breaks down, it forms stable humus and increases the soil's Cation Exchange Capacity (CEC). Humic and fulvic compounds bind essential mineral cations—calcium, magnesium, potassium, and trace elements—preventing them from leaching away during heavy rainstorms. Over three to five seasons of continuous surface mulching, even heavy clay or barren sand transforms into loose, crumbly, dark topsoil.

2. Wood Chips and Sawdust: Fungal Dominance and Pathway Engineering

Wood chips and sawdust represent the most carbon-dense, long-lasting mulching materials available to growers. They are durable, slow to decay, and alter the biological trajectory of the soil beneath them. However, they are also frequently misapplied in annual vegetable production.

Heartwood Chips vs. Ramial Chipped Wood (RCW)

To understand how wood chips interact with soil, we must separate standard industrial tree-service chips from Ramial Chipped Wood (RCW), known in French agricultural research as Bois Raméal Fragmenté (BRF).

Wood Feedstock Comparison
=============================================================================
Property             Standard Trunk Wood Chips       Ramial Chipped Wood (RCW)
-----------------------------------------------------------------------------
Source Material      Mature tree trunks & heartwood  Small branches (< 2.5" diam.)
Primary Composition  Lignin & dead heartwood cells   Cambium, buds, bark, leaves
Carbon:Nitrogen      400:1 to 700:1                  30:1 to 100:1
Decomposition Rate   Very slow (3 to 6+ years)       Moderate (1 to 2 years)
Biological Target    Pathways & orchard groundcover  Fungal-dominant soil building
Nutrient Contribution Low mineral release             Rich in P, K, Ca, and enzymes
=============================================================================

Industrial tree services often produce wood chips from mature, dead trunk wood. Trunk heartwood consists primarily of dense lignin and cellulose fibers with almost no soluble nutrients, yielding an extremely high Carbon-to-Nitrogen (C:N) ratio between 400:1 and 700:1. These chips break down very slowly and serve primarily as physical pathway paving.

Ramial Chipped Wood, a concept developed through decades of study at Laval University in Quebec, focuses exclusively on chipping deciduous tree branches and twigs under 2.5 inches (7 cm) in diameter.

• The Cambial Advantage: Young twigs contain the tree's active vascular cambium, newly formed sapwood, expanding buds, and soluble proteins.
• Nutrient Profile: RCW contains significantly higher levels of phosphorus, potassium, calcium, magnesium, and nitrogen than trunk heartwood.
• The Fungal Shift: RCW stimulates specialized basidiomycetes—white-rot fungi. White-rot fungi secrete laccase and manganese peroxidase enzymes, the only biological mechanisms capable of breaking down complex lignin polymers. As these fungi colonize the chips, they synthesize glomalin, an insoluble glycoprotein that creates long-lasting, water-stable soil aggregates.

Debunking the Nitrogen Tie-Up Myth

The most frequent concern raised by market gardeners considering wood mulches is: do wood chips tie up nitrogen in the soil?

The short answer is: only if you incorporate them into the soil.

The Nitrogen Tie-Up Boundary Dynamics
=============================================================================
SCENARIO A: WOOD CHIPS TILLED INTO SOIL (DISASTROUS)
[ Wood Fragment ]  Soil bacteria consume carbon from all sides.
      ▲  ▲  ▲      Bacteria pull all plant-available nitrate (NO3-) and
      │  │  │      ammonium (NH4+) out of the surrounding soil matrix.
[ Vegetable Roots] Cash crop roots starve of nitrogen; leaves turn pale yellow.
-----------------------------------------------------------------------------
SCENARIO B: WOOD CHIPS SPREAD ON SOIL SURFACE (SAFE & BENEFICIAL)
[ Wood Chip Mulch ] High-carbon blanket rests on surface.
═══════════════════ Microscopic interface boundary (< 1 millimeter thick)
[ Native Topsoil ]  Nitrogen tie-up is restricted to the top 1-2 millimeters.
      │  │  │      Vegetable roots feeding 2 to 8 inches deep enjoy full
[ Deep Root Zone ] access to native and amended nitrogen reserves.
=============================================================================

When high-carbon woody material is tilled or disked into the ground, soil bacteria swarm every buried wood particle. To manufacture cellular proteins while digesting that massive carbon influx, the bacteria pull every available molecule of nitrate ($NO_3^-$) and ammonium ($NH_4^+$) from the surrounding soil solution. Because bacteria have a vastly higher surface-area-to-volume ratio than crop roots, they outcompete your vegetables for nitrogen, causing severe chlorosis and stunted growth.

However, when wood chips are applied strictly as a surface mulch, nitrogen immobilization is limited to the microscopic contact zone between the bottom of the chip layer and the top millimeter of soil.

Peer-reviewed research led by Dr. Linda Chalker-Scott at Washington State University Extension has repeatedly demonstrated that surface wood chip mulches do not pull nitrogen out of the underlying root zone. Plant roots operating two to six inches beneath the soil surface have unimpeded access to soil nutrients.

Over time, as wood chips slowly decay on the surface, fungal mycelium transports nitrogen upward from the soil interface while releasing humic substances downward, steadily enriching the topsoil.

Evaluating the "Back to Eden" Method for Commercial Growing

The "Back to Eden" gardening system—popularized by Paul Gautschi—involves laying down thick cardboard or compost and covering it with four to eight inches of arborist wood chips. While this approach has transformed millions of home gardens, commercial market gardeners must weigh its clear advantages against several distinct operational bottlenecks.

The Advantages

• Unrivaled Drought Tolerance: Deep wood chips create a dense sponge. In temperate climates, established Back to Eden gardens can frequently go entire summers without supplemental irrigation.
• Deep Fungal Succession: Over three to four seasons, the soil beneath the chips develops a thick, spongy layer of fungal duff that smells like rich woodland soil.
• Zero Pathway Mud: Even during torrential spring downpours, wood chip walking paths remain firm, clean, and mud-free.

The Commercial Limitations

• Direct Seeding Is Impractical: You cannot push a precision walk-behind seeder (such as a Jang JP-1 or EarthWay) through chunky wood chips. Fine seeds like carrots, beets, spinach, and baby greens require direct soil-to-seed contact and a finely textured seedbed. Attempting to rake back coarse wood chips to seed forty rows of baby greens takes far too much labor.
• Delayed Spring Soil Warm-Up: Thick wood chip mulch acts as a refrigerator in early spring. Soil beneath deep wood chips can remain 10°F to 15°F colder than bare or tarped ground well into May, delaying early plantings of heat-loving solanaceous crops.
• Mollusk and Pest Sanctuaries: In humid regions like the Southeast, the cool, perpetually damp environment under deep wood chips creates a breeding ground for slugs, snails, and pillbugs (Armadillidium vulgare), which can sever young vegetable transplants at the soil line overnight.

Where Wood Chips Belong: Pathways, Perennials, and Orchards

Because of direct-seeding restrictions, experienced market gardeners rarely cover active annual vegetable beds in chunky wood chips. Instead, wood chips are the undisputed best mulch for permanent garden pathways.

Spreading three to four inches of aged arborist chips or ramial wood chips down your eighteen-inch walking paths achieves multiple farm goals simultaneously:

1. It eliminates walking path weeds without herbicides, string trimmers, or flame weeders.
2. It keeps farm boots, carts, and harvest totes free of mud during wet market harvests.
3. It serves as a continuous, fungal-dominated composting trench. The root systems of vegetable crops growing in adjacent thirty-inch raised beds will readily tunnel horizontally beneath the path to mine the fungal moisture and mineral nutrients trapped under the wood chips.

Wood chips are also the premier mulch choice for perennial crops—including fruit trees, berry patches, asparagus beds, and rhubarb plantings—which thrive in fungal-dominant soil ecosystems and do not require seasonal replanting.

3. Cereal Straw: The Agile, Bacterial Blanket for Annual Vegetables

If wood chips serve as the durable, long-term foundation for pathways and perennials, clean cereal straw is the agile, seasonal protector for annual vegetables. Straw consists of the dry, hollow stems of harvested cereal grains—primarily wheat, oats, barley, or rye—left behind after the grain seed heads have been threshed and removed.

Straw vs. Hay: The Mistake That Ruins Garden Beds

Beginner growers frequently use the terms "straw" and "hay" interchangeably. Confusing the two materials can turn a productive garden bed into a weed-choked nightmare.

Straw versus Hay: Critical Distinctions
=============================================================================
Characteristic       Cereal Straw                    Agricultural Hay
-----------------------------------------------------------------------------
Primary Purpose      Harvest byproduct / bedding     Livestock feed & forage
Plant Composition    Hollow stems of grain crops     Whole grasses & legumes
Seed Head Presence   None (Threshed during harvest)  Abundant (Mature weed/grass seeds)
Carbon:Nitrogen      80:1 to 100:1                   20:1 to 35:1
Weed Pressure Risk   Minimal (If clean & unweathered) Catastrophic (Thousands of seeds)
Suitability          Ideal for annual vegetable mulch Avoid entirely in no-till beds
=============================================================================

• Hay is a forage crop (such as timothy, orchard grass, fescue, or alfalfa) cut green while seed heads are mature and baled specifically as animal feed. Spreading hay across a no-till garden bed intentionally broadcasts tens of thousands of pasture grass and perennial weed seeds across your growing space.
• Straw is the dry, hollow structural stem left behind after grain harvesting. A properly harvested straw bale contains clean, seed-free carbon tubes.

The Threat of Persistent Pyridine Herbicides

While straw is an outstanding mulch, modern growers must navigate a serious agronomic hazard: persistent broadleaf herbicides.

Conventional grain producers and hayfield managers frequently apply synthetic auxin-mimicking herbicides belonging to the pyridine and pyrimidine carboxylic acid chemical families. Common active ingredients include:

• Aminopyralid (Milestone, ForeFront)
• Clopyralid (Stinger, Transline)
• Picloram (Tordon)

These chemicals are engineered for extraordinary environmental persistence. They do not break down in livestock digestive tracts, they survive high-temperature thermal composting, and they persist on dry straw stalks for two to three years.

When contaminated straw is spread on vegetable beds, even microscopic residues (at levels as low as one part per billion) cause severe, irreversible hormonal damage to broadleaf crops:

• Tomatoes develop twisted, fern-like, cupped leaves and fail to set fruit.
• Beans and peas emerge severely stunted with distorted, hook-shaped growing tips.
• Nightshades, cucurbits, and legumes suffer catastrophic crop failure.

The 14-Day Broadleaf Herbicide Bio-Assay Protocol
=============================================================================
Step 1: Collection   Take handfuls of straw from random bales in the shipment.
Step 2: Preparation  Chop straw finely with shears; mix 50/50 with potting soil.
Step 3: Planting     Fill 3 pots with straw mix (Test); fill 3 pots with pure
                     potting soil (Control). Plant 3 pea or bean seeds per pot.
Step 4: Incubation   Place under grow lights; keep moist with clean water.
Step 5: Assessment   Observe 1st and 2nd sets of true leaves at 10-14 days.
                     * Straight, vigorous, normal leaves → Straw is SAFE.
                     * Cupped, twisted, fern-like growth → CONTAMINATED (Reject).
=============================================================================

Never spread unverified agricultural straw on your cash crop beds without either purchasing certified organic bales or performing a 14-day bio-assay using sensitive legume seeds.

Rapid Bacterial Decomposition and Soil Conditioning

Unlike the dense lignin structure of wood chips, the cell walls of cereal straw are composed predominantly of cellulose and hemicellulose. Straw stalks are hollow, providing a massive internal and external surface area for microbial colonization.

When straw rests on moist topsoil, aerobic bacteria and soft-rot fungi decompose the material rapidly. An eight-inch layer of straw spread in June will break down by seventy to eighty percent over the course of a single growing season. By the following spring, earthworms and soil microbes have converted the straw into dark, crumbly surface humus.

This rapid biological cycling is ideal for annual market gardens. It provides all the moisture retention and weed-smothering benefits of deep mulch during the heat of summer, without leaving behind stubborn woody debris that interferes with the following spring's bed preparation.

Ideal Vegetable Applications for Straw Mulch

Straw delivers exceptional results around specific heavy-feeding, long-season annual crops:

• Solanaceous Transplants (Tomatoes, Peppers, Eggplants): Spreading four to six inches of straw around transplants creates a physical barrier that prevents rain from splashing soil-borne fungal spores (Septoria lycopersici, Alternaria solani) onto lower leaves.
• Cucurbits (Squash, Zucchini, Melons, Cucumbers): Straw keeps heavy, soft-skinned fruits elevated off damp soil, preventing belly rot, fungal spotting, and ground-scarring.
• Overwintered Garlic: Mulching autumn-planted garlic beds with six inches of straw prevents frost-heaving during winter freezes and preserves soil moisture throughout the rapid spring bulbing phase.
• Potatoes: In "straw potato" systems, seed potatoes are placed directly on the soil surface and covered with twelve inches of clean straw, allowing for clean, knobby-free tubers that can be harvested by hand without digging.

5. Managing Nitrogen Dynamics and Soil Thermodynamics

Successfully managing deep mulch systems requires active observation of soil physics and biology across changing seasons.

The Spring Mulch Transition Sequence
=============================================================================
Early Spring (4 Weeks Pre-Plant):
[ Native Soil ]   Rake winter straw mulch off planting rows into pathways.
                  Dark soil absorbs direct sunlight, warming root zone.
-----------------------------------------------------------------------------
Transplant Day:
[ Direct Soil ]   Dig transplant holes, incorporate compost/fertilizer,
                  install drip irrigation tape directly on native soil.
-----------------------------------------------------------------------------
Late Spring (Summer Transition):
[ 4" Straw Layer] Push straw back around base of plants, burying drip lines.
                  Locks in moisture, stabilizes soil temp at optimal 72°F.
=============================================================================

The Spring Rake-Back Protocol

One of the most common mistakes made by growers adopting deep mulch systems is leaving thick mulch covering their beds through late winter and early spring.

Because organic mulches are exceptional insulators, a six-inch layer of winter straw will prevent solar radiation from reaching the soil. Soil temperatures beneath deep mulch can lag behind bare ground by up to three weeks. If you attempt to plant warm-season crops like tomatoes, peppers, or squash into cold, mulched soil, the plants will sit dormant, turn purple from phosphorus lockout, and fall prey to soil-borne damping-off fungi.

To manage spring thermodynamics correctly:

1. Four Weeks Before Planting: Walk your beds and use a leaf rake or pitchfork to pull the mulch back from the center of the beds, piling it neatly along the edges or down the pathways.
2. Solar Exposure: Expose the dark soil surface to direct sunlight. You can combine this with clear occultation tarps to rapidly elevate bed temperatures above 65°F (18°C).
3. Planting and Re-Mulching: Once the soil has thoroughly warmed and transplants are set in place with drip irrigation lines installed beneath them, push the mulch back around the base of the established plants to shield the root zone before summer heat arrives.

Mitigating Nitrogen Demand at the Soil Interface

While surface mulches do not pull nitrogen out of deep root zones, high-carbon mulches do consume nitrogen at the immediate soil-mulch interface. If your soil has low baseline fertility or if you are working with newly established no-till beds, this minor surface immobilization can slightly slow early crop growth.

To satisfy the decomposer demand without depriving your cash crops:

• Under-Mulch Amending: Always apply your baseline organic soil amendments—such as aged compost, alfalfa meal, feather meal, or pelleted poultry manure—directly to the soil surface before spreading your straw or wood chip mulch layer.
• Biological Priming: The moisture beneath the mulch will rapidly activate the microbial breakdown of these organic fertilizers, feeding both the crop root zone and the lower decomposer layer simultaneously. Learn more about biological mineral cycling in our detailed manual on Understanding Cation Exchange Capacity (CEC).

6. Practical Field Protocols: Sourcing, Application, and Pest Management

Executing deep mulch systems on a production scale requires efficient sourcing, careful material handling, and proactive pest monitoring.

Sourcing Clean Feedstocks

• Finding Quality Wood Chips: Contact local tree care companies and municipal utility line-clearing crews. Ask the arborist about the species composition before accepting a chip drop. Request mixed deciduous wood chips (oak, maple, birch, ash) and avoid loads containing more than twenty percent coniferous pine or cedar. Never accept loads containing black walnut (Juglans nigra), as walnut tissue contains juglone, a potent allelopathic quinone that stunts and kills solanaceous crops (tomatoes, peppers, potatoes).
• Sourcing Clean Cereal Straw: Purchase straw directly from local grain farmers rather than retail big-box garden centers whenever possible. Inquire directly about their herbicide spray programs. Ask specifically whether Milestone, Stinger, Grazon, or any pyridine-based broadleaf chemicals were applied to the field or surrounding borders during the growing season. If they cannot verify the chemical history, perform the legume bio-assay before spreading.

Application Thickness Benchmarks

• Pathways (Wood Chips): Spread aged wood chips at an initial depth of three to four inches. Replenish with an additional one to two inches every autumn to suppress newly introduced weed seeds and maintain a comfortable walking surface.
• Vegetable Beds (Straw): Shake out compressed straw flakes by hand, teasing the stalks apart to create an initial loose, fluffy layer eight to ten inches thick. Once watered by irrigation or rainfall, the straw will settle into a uniform, interwoven four- to five-inch light-blocking mat.

Mulch Application Depth Guide
=============================================================================
Zone                  Material          Initial Depth     Settled Depth
-----------------------------------------------------------------------------
Permanent Pathways    Ramial Wood Chips 4 to 5 inches     3 to 4 inches
Fruiting Crops Beds   Cereal Straw      8 to 10 inches    4 to 5 inches
Garlic & Overwinter   Cereal Straw      6 to 8 inches     3 to 4 inches
Orchard & Perennials  Aged Wood Chips   5 to 6 inches     4 to 5 inches
=============================================================================

Proactive Pest Management: Mollusks and Rodents

Deep mulch creates an ideal environment for beneficial organisms, but it can also shelter unwanted garden pests if left unmanaged.

• Slugs and Snails: In wet climates, thick mulch provides the cool, dark sanctuary slugs love. To keep slug populations in check:
  • Keep mulch pulled back two to three inches from the immediate succulent stems of tender young transplants.
  • Water beds exclusively via drip irrigation lines laid beneath the mulch, keeping the top of the straw dry.
  • Scatter approved organic iron phosphate bait (such as Sluggo) along pathway edges during prolonged rainy stretches.
• Voles and Mice: Burrowing rodents love tunneling beneath deep mulch to chew on succulent root crowns and irrigation tubing.
  • Maintain a clean, mowed buffer zone around the perimeter of your garden plot to expose rodents to predatory hawks, owls, and barn cats.
  • In late autumn, pull mulch back several inches from the trunks of perennial fruit trees to prevent winter bark girdling.

7. Diagnostic Troubleshooting Guide for Deep Mulch Systems

Conclusion: The Integrated Mulch Farm Design

The experienced regenerative grower does not view wood chips and straw as competing materials. Instead, the most productive no-till operations integrate both materials into a harmonious, dual-zone farm layout.

The Unified No-Till Dual-Mulch System

-----------------------------------------------------------------------------
[ PATHWAY ]       3" - 4" Aged Ramial Wood Chips (Fungal Dominance)
=============================================================================

By putting aged ramial wood chips where they excel—in permanent walking pathways, perennial borders, and orchard rows—you establish durable, mud-free walking lanes that cultivate fungal networks and slowly condition your soil for years.

By applying clean cereal straw where it excels—blanketing thirty-inch annual vegetable beds around tomatoes, peppers, garlic, and cucurbits—you conserve irrigation water, protect foliage from soil-borne diseases, and steadily build crumbly topsoil that breaks down cleanly each season.

Put down the rototiller, respect the biological differences between bacterial and fungal decomposition, and let deep organic mulches do the heavy lifting on your farm. Your soil biology, your crops, and your back will thank you for years to come.
