ORGANIC FARMING

BY:RATIKA DELHI INDIA

Organic farming is a type of agriculture that benefits from the recycling and use of natural products. Extensive use of dried foliage and kitchen compost not only reduces the investment overheads, but also ensures the growth of crops that are devoid of synthetic interference. The technique is characterized by the use of green manure, biological pest control methods and special cultivation techniques to maintain soil productivity. Limiting the use of synthetic fertilizers or completely doing away with them reduces the risk of exposure to ailments that arise on account of synthetic pesticides, ingrained plant growth regulators and the presence of genetically modified organisms in organic food products.

Organic farming refers to ecologically-based production systems used to produce food and fiber.

Organic farming can be defined by the proactive, ecological management strategies that maintain and enhance soil fertility, prevent soil erosion, promote and enhance biological diversity, and minimize risk to human and animal health and natural resources.

INTRODUCTION


COMPONENTS


NEED OFORGANIC FARMING

Drawbacks of green revolution:Rapidely degrading soil fertility statusIncreased cost of productionIncreased environmental pollutionHealth hazardsThats why, we need organic

farming.

Organic farming describe 2 major aspects of alternative agriculture-Substitution of organic manure & other material for inorganic fertilizersBiological pest & control instead of the chemicals.

CONCEPT OF ORGANIC FARMING


ADVANTAGES OFORGANIC FARMING

The study found that organic fruits and vegetables have up to 50% more antioxidants, and more vitamins and minerals, such as iron and zinc.Other studies have shown that by eating organic foods, people have a stronger immune system, less weight problems, and better sleep.•you're not ingesting deadly pesticides, poisons and herbicides•keeps pesticides out of streams and ground water•better tasting, more flavor•no residual antibiotics or growth hormones in organic meat or milk

• no fillers are used to bulk up foods• food is non-GMO (genetically modified organism) • pure - no artificial colors, flavors, additives, preservatives, sweeteners• it is not processed• supports local farms and farmers, and the local economy• safer to eat for babies and children• more healthy ,higher nutrition content, more vitamins, minerals, essential fatty acids• emotional benefits - feeling good about eating something that is pure food, healthy for you, and tastes better than processed food and you are helping the environment• pesticides in foods have been linked to several diseases: cancer, obesity and some birth defects.


Organic is fundamentally different from Conventional because of the use of carbon based fertilizers compared with highly soluble synthetic based fertilizers and biological pest control instead of synthetic pesticides, which proves organic farming to be more beneficial.

CONVENTIONAL VS

ORGANIC FARMING

Pollute rivers, lakes and water sources.Poor soil structure; easily erodedDependency on fertilizers to produce

crop.Pesticides enter the food- health

problems.Chemicals destroy soil micro-organismsDevelopment of Pests and diseases

resistance to artificial pesticides.The numbers of natural enemies

decrease because of pesticide use and habitat loss.

PROBLEMS WITH CONVENTIONAL FARMING

The farmer would use a range of organic methods at the same time to allow them to work together for the maximum benefit.

These techniques aiming at: Maintain and build good soil structure and fertility Control pests, diseases and weeds Careful use of water resources Good animal husbandry

TECHNIQUES IN ORGANIC FARMING


Activities to maintain and build good soil structure and fertility:

Recycled and composted crop wastes and animal manures (organic fertilizers)The right soil cultivation at the right timeCrop rotation Green manuresMulching on the soil surface and cover crops.


Composting

Compost improves soil structure, allows more air into the soil, improves drainage and reduces erosion.

Compost improves soil fertility by adding nutrients and by making it easier for plants to take up the nutrients already in the soil.

It improves the soil’s ability to hold water thus prevent drying out during drought.


Crop Rotations

The practice of growing a series of dissimilar types of crops in the same area in sequential seasons.

Mitigates the build-up of pathogens, weeds and pests that often occurs when one species is continuously cropped.


Green manures

In agriculture, green manure refers to crops which have already been uprooted (and have often already been stuffed under the soil). The then dying plants are of a type of cover crop.

Increase and recycle plant nutrients and organic matter

Improve soil fertility & soil structureImprove the ability of the soil to hold

waterControl soil erosion


Mulching

Covering the ground with a layer of loose material such as straw, dry grass, leaves or crop residues.

Decreasing water loss due to evaporationSuppressing weed growthPreventing soil erosionAdd nutrients and improving soil

The use of terracing and careful irrigation- decrease erosion and surface runoffThe addition of organic matter to the soil to improve its ability to hold waterThe use of mulches to hold water in the soil by stopping the soil surface from drying out.

Careful use of water:


The term can refer to the practice of selectively breeding and raising livestock to promote desirable traits in animals for utility, sport, pleasure, or research Animals should not be kept in confined spaces where they cannot carry out their natural behavior such as standing and moving around in an inadequate amount of space. Breeds should be chosen to suit local needs and local conditions and resources.
