What is organic farming?
Organic farming is a way of growing crops and raising animals without synthetic (factory-made) fertilisers, synthetic pesticides, growth hormones or genetically modified seeds.
The big idea is simple: feed the soil, and the soil feeds the plant. Healthy soil is full of humus, earthworms and tiny microbes. They slowly release nutrients to the roots.
Main principles
- Health: healthy soil, plants, animals and people.
- Ecology: work with natural cycles, not against them.
- Fairness: fair to farmers, workers and buyers.
- Care: protect the land for the future.
Organic inputs: feeding the soil
- Farmyard manure (FYM): rotted dung, urine and bedding of farm animals.
- Compost: crop waste and kitchen waste broken down by microbes into dark humus.
- Vermicompost: compost made by earthworms (for example the red wiggler, Eisenia fetida). It is fine, rich and fast to make.
- Green manure: a quick crop such as sunn hemp or dhaincha is grown and ploughed into the soil while green.
- Biofertilisers: living microbes that add nutrients. Rhizobium lives in pulse root nodules and fixes nitrogen; Azotobacter fixes nitrogen freely in soil; blue-green algae help paddy; phosphate-solubilising bacteria and mycorrhiza fungi help roots take up phosphorus.
- Oil cakes and bone meal: slow-release nutrients.
Natural pest, weed and disease control
Organic farmers use integrated pest management (IPM) without synthetic poisons:
- Biological control: natural enemies such as ladybirds (eat aphids), Trichogramma wasps (destroy moth eggs) and the bacterium Bacillus thuringiensis (Bt) that kills caterpillars.
- Botanical sprays: neem oil and neem seed extract.
- Traps: yellow sticky traps, light traps and pheromone traps.
- Cultural control: resistant varieties, right sowing time, trap crops (marigold around tomato), clean fields.
- Weeds: mulching, hand or machine weeding, cover crops.
Crop rotation, mixed cropping and advanced practices
Crop rotation means growing different crops one after another on the same land. A pulse (legume) after a cereal returns nitrogen and breaks pest cycles. Mixed and intercropping grow two crops together, for example sorghum with pigeon pea.
Advanced crop production practices
- Drip and sprinkler irrigation: water goes straight to the roots; saves 30–60% water. Fertigation sends dissolved nutrients through the drip line.
- Mulching: straw or plastic sheet keeps moisture in and weeds out.
- Protected cultivation: polyhouses, greenhouses, shade nets and low tunnels give crops the right climate.
- Hydroponics: plants grow in nutrient water instead of soil.
- Precision farming: soil tests, GPS, sensors and drones give each patch just what it needs.
- Improved seeds, seed treatment, zero tillage and integrated nutrient management.
Benefits, limits and organic certification
Benefits
- Better soil structure and more soil life.
- No synthetic residues in food, water or farm workers' bodies.
- Lower cost of bought inputs; higher selling price.
- Supports bees, birds and other biodiversity.
Limits
- Yields often fall for the first 2–3 years (the conversion period).
- Needs more labour and large amounts of manure.
- Certification costs money and paperwork.
Certification
A farm must follow organic rules for a conversion period (usually 2–3 years). An inspector checks records and fields. Approved food carries an organic logo, such as India Organic, the EU leaf logo or USDA Organic. Small farmers can also use group schemes such as PGS (Participatory Guarantee System).
Try it: compost in a pot
Mix 2 parts dry leaves with 1 part vegetable peels in a pot with holes. Add a handful of garden soil, keep it damp like a squeezed sponge and turn it weekly. After 6–8 weeks it smells earthy and looks dark: that is humus. Grow herbs in it and compare with plain soil.
Key formulas and definitions
- Organic farming = no synthetic fertiliser + no synthetic pesticide + no GM seeds
- Vermicompost: organic waste + earthworms → nutrient-rich worm castings
- Biofertiliser: Rhizobium (pulses), Azotobacter (free-living), blue-green algae (paddy)
- Crop rotation: cereal → legume → vegetable restores soil nitrogen
- IPM = biological + cultural + mechanical control, chemicals only as a last resort
- Conversion period: usually 2–3 years before produce can be sold as certified organic
Worked examples
1. A farmer grows wheat every year and the yield keeps falling. Suggest an organic solution.
Rotate crops: grow a pulse such as chickpea or lentil after wheat. Rhizobium in the root nodules fixes nitrogen from the air, so the next wheat crop gets more nitrogen. Also add compost or FYM to raise humus.
2. Aphids are attacking a mustard field. How can they be controlled organically?
Release or protect ladybird beetles that eat aphids, spray neem seed extract, and put yellow sticky traps around the field. No synthetic pesticide is used.
3. Drip irrigation needs 2,000 L of water for a plot that needed 5,000 L with flood irrigation. What percentage of water is saved?
Water saved = 5,000 − 2,000 = 3,000 L. Percentage = 3,000 ÷ 5,000 × 100 = 60%.
Common mistakes
- Thinking organic means 'no fertiliser at all'. Organic farms use plenty of fertiliser, but natural ones like compost and manure.
- Thinking any farm without chemicals can use the organic label. Only certified farms (after the conversion period) can.
- Mixing up biofertilisers and biopesticides: Rhizobium adds nitrogen; Bt kills caterpillars.
- Believing crop rotation means rotating the same crop to another field. It means changing the crop on the same field over seasons.
