What is Organic Farming?

Chemical fertilisers kill soil microorganisms over time creating a dependency cycle. Organic farming rebuilds soil biology. Feed the SOIL not the plant — healthy soil makes nutrients available naturally, produces food with no pesticide residue, and costs less after year 3 as input costs drop.

Why Organic Farming?

•Year 1: Transition — yield may drop 10-20%

•Year 2: Soil recovers — same yield as chemical

•Year 3+: Better yield, near-zero input cost, 20-50% premium selling price

Learning Modules

Module 01 — Why Organic Farming?

What chemicals do vs what nature does better

Chemical fertilisers (urea, DAP) give quick results but kill soil microorganisms over time. Dead soil needs more and more chemicals — a dependency cycle. Organic farming rebuilds soil biology.

Topics covered:

•How chemical fertilisers damage soil long-term — 🟢 Beginner

•What organic farming actually means — 🟢 Beginner

•Health benefits of chemical-free produce — 🟢 Beginner

•Cost comparison: organic vs chemical farming — 🟡 Intermediate

•Organic certification — PGS-India basics — 🟡 Intermediate

bash

# CHEMICAL PROBLEM:
# Year 1: Apply urea+DAP — good yield
# Year 7: Soil dead, needs 3x chemicals, farmer in debt

# ORGANIC SOLUTION:
# Year 1: Transition — yield may drop 10-20%
# Year 2: Soil recovers — same yield
# Year 3+: Better yield, near-zero input cost, premium price

# STOP: Urea, DAP, MOP, synthetic pesticides, glyphosate
# START: Compost, vermicompost, jeevamrut, neem, mulching

Module 02 — Soil Preparation

Compost, vermicompost, jeevamrut, mulching

Good soil is dark, crumbly, sweet-smelling and full of earthworms. Compost is decomposed kitchen and farm waste. Vermicompost is 7x more nutritious. Jeevamrut activates billions of soil microorganisms.

Topics covered:

•How to make compost at home in 45-60 days — 🟢 Beginner

•Vermicompost — 7x nutrients vs regular compost — 🟢 Beginner

•Jeevamrut — Subhash Palekar ZBNF method — 🟡 Intermediate

•Soil testing: pH and nutrients — 🟡 Intermediate

•Mulching — 50% water saving — 🟢 Beginner

bash

# COMPOST — ready in 45-60 days
# Ratio: 3 parts dry (leaves, cardboard) : 1 part wet (kitchen waste)
# Add cow dung as activator
# Turn every 7-10 days, keep moist
# Apply: 1-2 kg per sq.metre before planting

# JEEVAMRUT (for 200 litres):
# 10 kg desi cow dung + 5L cow urine
# 2 kg jaggery + 2 kg gram flour
# Handful soil from under large tree
# Ferment 48 hours, stir twice daily
# Use: 10% dilution, drench soil every 15 days
# Benefit: Activates 300 crore microorganisms per ml

# MULCHING: 3-4 inches dry leaves or rice straw
# Reduces watering by 50%, suppresses weeds

Module 03 — Terrace & Home Garden

200 sq.ft can grow 70% of family vegetables

A 200 sq.ft terrace can grow 60-70% of a family's daily vegetable need. Key: right container depth, good soil mix, 4-6 hours sunlight. Best season in India: winter October to February.

Topics covered:

•Container depth guide by crop type — 🟢 Beginner

•Best soil mix for containers — 🟢 Beginner

•Season-wise planting guide for India — 🟢 Beginner

•Companion planting — 🟡 Intermediate

•Vertical gardening for small spaces — 🟡 Intermediate

bash

# CONTAINER DEPTH GUIDE:
# SHALLOW 6-8 inches: coriander, methi, spinach, radish, microgreens
# MEDIUM 10-12 inches: tomato, chilli, capsicum, beans, cucumber, okra
# DEEP 14-18 inches:   carrot, potato, beetroot, turmeric, ginger

# SOIL MIX FOR CONTAINERS:
# 40% garden soil + 30% vermicompost + 20% cocopeat + 10% sand

# SEASONAL PLANTING (India):
# SUMMER Feb-June:  okra, cucumber, bitter gourd, amaranth
# MONSOON Jul-Oct:  leafy greens, ginger, turmeric, beans
# WINTER Oct-Feb:   tomato, chilli, peas, carrot, cauliflower (BEST season)

Module 04 — Natural Pest Control

Neem, panchagavya, organic sprays — zero chemicals

Neem disrupts the life cycle of 200+ insect pests without harming bees or birds. Prevention is always better than cure. 80% of pest problems come from unhealthy soil or stressed plants.

Topics covered:

•Neem oil spray — works on 200+ insect pests — 🟢 Beginner

•Panchagavya — immunity booster and growth promoter — 🟡 Intermediate

•Chilli-garlic spray for insects — 🟢 Beginner

•Bordeaux mixture for fungal diseases — 🟡 Intermediate

•Yellow sticky traps for flying insects — 🟢 Beginner

bash

# NEEM SPRAY (most important organic pesticide):
# 5 ml neem oil + 1-2 ml liquid soap per litre water
# Shake well, spray both sides of leaves in evening
# Every 7-10 days preventively
# Works on: aphids, whitefly, mites, caterpillars, fungal diseases

# CHILLI-GARLIC SPRAY:
# 10 green chillies + 10 garlic cloves blended in 1L water
# Strain, dilute 1:10, spray on plants

# BORDEAUX MIXTURE (fungal diseases):
# 100g copper sulphate + 100g lime in 10L water
# Apply before monsoon to prevent blight and rust

Module 05 — Crop-Specific Organic Guides

Rice, vegetables, fruits, spices, dal, cotton

SRI rice method uses 50% less water and increases yield 30-50% with no chemicals. Turmeric is the easiest organic crop. Dal crops (legumes) fix nitrogen from air — they actually improve soil for the next crop.

Topics covered:

•Rice — SRI method: 50% less water, higher yield — 🟡 Intermediate

•Turmeric and ginger — easiest organic crops — 🟡 Intermediate

•Dal crops — nitrogen fixing, minimal inputs — 🟡 Intermediate

•Mango and banana organic orchard care — 🟡 Intermediate

•Organic cotton farming — 🔴 Advanced

•Corn and vegetable stage-wise inputs — 🟢 Beginner

bash

# SRI METHOD FOR RICE (System of Rice Intensification):
# 1. Young seedlings 8-12 days old (2-leaf stage)
# 2. Single seedling per hole (not clumps)
# 3. Wide spacing: 25x25 cm (vs 15x15 traditional)
# 4. Alternate wet-dry irrigation (not flooding)
# 5. Mechanical weeder for weed control
# Organic inputs: compost + jeevamrut
# Result: 6-8 tonnes/acre vs 3-4 tonnes chemical

# TURMERIC:
# Plant: April-May (monsoon onset), spacing 30x30 cm
