VEGANIC FARMING AND GARDENING


Veganic farming and gardening

Veganic farming and gardening is a willingness to balance our existence with the natural world.

the soil microorganisms we try not to disturb with excessive tillage, the birds, butterflies, and insects we do not poison with insecticides, the weeds that are not killed with herbicides, and the animals who are not killed for food.


Unlike conventional organic

Unlike Conventional Organic,

Tillage to manage weeds and water


Veganic is livestock free and does not use manure as a fertilizer

Veganic is livestock-free and does not use manure as a fertilizer…..

Manure problems: herbicide contamination, nitrate-N leaching into ground water, human pathogens such as ecoli…..


Veganic farming and gardening

Veganic Works With Nature to Mimic Natural Plant Eco-Systems:

Reduced tillage – keeping soil covered,

Increased plant diversity,

Regular addition of plant residues.


Veganic farming and gardening

Increased plant diversity, regular additions of plant residues, & keeping the soil covered promotes a healthy soil & Rhizospere (root-soil zone of greatest soil foodweb activity)


There are many ways to add plant residues

To create a healthy rhizsphere: add plant residues.

There are many ways to add plant residues…..


Alfalfa pellets added to greenhouse tomatoes provide nitrogen phosphorus and potassium

Veganic farming and gardening

Sheet composting or mulching – surface application of grass clippings or hay

In a perfect world we would be able to harvest our own hay for veganic growing and wait until mid July to cut, so most grassland birds (and small mammals) have fledged their young. Though less nitrogen and more viable seed in a late cutting, later cut hay holds up better over time - suppressing weeds longer. A late cutting will allow insects to work flowers - at least until the hay is cut.

Dead Mulch – straw and leaves

Cover crops and green manures spring tillage incorporation into soil

Cover Crops and Green Manures (spring tillage/incorporation into soil)


Veganic farming and gardening

Perennials: Rye grass (Lolium) mixed with hairy vetch – good balance of nitrogen and carbon.


Veganic farming and gardening

Oats and Red Clover

(combinations of grasses and legumes are usually best for weed suppression)


Veganic farming and gardening

Clovers provide the best levels of nitrogen when mowed or tilled into the soil

White Clover


Crown vetch another good nitrogen source

Crown Vetch – another good nitrogen source.


Veganic farming and gardening

Annuals –

Buckwheat accumulates phosphorus.


Veganic farming and gardening

Rye (Secale) – annual – allelopathic (when tilled into the soil, produces biochemicals that inhibit seed germination and seedling growth).


Veganic farming and gardening

Parabinga medic – handles high pH and low moisture once established


Veganic farming and gardening

Snail Medic – drought tolerant once estblished


Veganic farming and gardening

Winter kills in cold climates


Veganic farming and gardening

Brassicas – Rape – allelopathic:

Inhibits weeds and root rot diseases


Annual ryegrass lower nitrogen than legume living mulches or cover crops

Annual Ryegrass – lower nitrogen than legume living mulches or cover crops.


Veganic farming and gardening

Which organic residue to use?

Depends on soil type, texture and pH, precipitation, and temperature…and cropping system

Veganic farming and gardening

Green and succulent plant residues (higher nitrogen) vs. brown and dry residues (lower nitrogen, higher carbon)

High carbon materials can temporarily steal nitrogen from crop plants as microorganisms break them down


Veganic farming and gardening

Brown and dry

Green and succulent

Bio chemical pathways of decomposition both residue types break down to humus, but with different microorganisms and nutrient release rates.Green/succulent = fasterBrown/dry = slower


Green manures suppress disease bare soil fallow more disease

Green Manures Suppress Disease –bare soil (fallow) = more disease.


Veganic farming and gardening

Organic residues suppressed disease at different levels –alfalfa hay was best.

TILLAGE AFFECTS DISEASE SUPPRESSION

Pythium Suppression Decreases With Cultivation Intensity

Using living mulches

Case study @ Biodesign Farm


Soil covered spring summer fall winter

Soil covered spring, summer, fall, & winter.


Light tillage in the spring lots of residue left

Light tillage in the spring (lots of residue left)


Bed making residue inside beds

Bed making – residue inside beds


Veganic farming and gardening

Seed new cover between rows in spring, recruits from previous season’s living mulch already re-growing


New living mulch well established when we plant transplants of warm season crops

Mature living mulch kept mowed monthly surface applied residue

Mature living mulch kept mowed monthly (surface-applied residue)


Benefits of living mulch system balanced nutrient supply

Veganic farming and gardening

LM has different nutrients and C:N ratio at different times of the year. High C:N ratio material (greater than 30-50) may cause temporary unavailability of N and P.


Veganic farming and gardening

Soil Fertility Summary: Apply plant residue additions throughout the season; mix higher and lower C and N materials


Veganic farming and gardening

With careful planning, veganic farming and gardening can be bountiful and productive as well as kind to the other organisms with whom we share the earth
