Organic Manure : An Overview

1. Organic Manure : An Overview

2. Organic Manure : An Overview Introduction Organic manure is defined as the product resulting from the controlled biological decomposition of organic matter. • Manure can be prepared from : • yard trimmings • bio-solids (sewage sludge) • wood by-products • animals manures • crop residues • biodegradable packing • food scraps

3. Characteristics of Organic Matter Organic Manure : An Overview Organic matter is the key constituent of cultivated soils. It has profound influence on the physico-chemical and biological characteristics of soil.

4. Chemical Composition of Organic Matter Organic Manure : An Overview Carbohydrates (sugar, starch, hemi-cellulose, pectins gums, mucilages, etc.) Proteins, amino acids, amines, etc. Fats, oils, waxes, resins, etc. Alcohols, aldehydes, ketones, etc. Lignins Compounds containing ring structure (phenol, tennis, hydrocarbon) Alkaloids and compounds with organic base- pyrimidine and purines Miscellaneous substances like antibiotics, auxins, vitamins, enzymes and pigments

8. Animal manure Organic Manure : An Overview Farm yard manure (FYM) Farm slurry or Liquid manure (Agricultural manure in liquid form known as slurry Manure formed of cattle excreta mixed with straw, used as a fertilizer Click here Click here

9. A. Farm Yard Manure Organic Manure : An Overview Farm Yard Manure can be prepared by : • Cow dung, • Cow urine, • Waste straw and • Dairy waste, etc. NEXT

10. Cow dung Manure Organic Manure : An Overview This is a type of Farm Yard Manure Cow manure is rich in humus, the bulky and fibrous material that comes from undigested plant matter. Cow manure is composted by putting it into a bin or pile and letting it decompose It contains about 3 percent nitrogen, 2 percent phosphorous, and 1 percent potassium NEXT

11. Method of preparation of FYM Organic Manure : An Overview Dig a pit (4×6×10) near cattle shed above the level of soil. Spread the excavated soil on the surface. Fill the pit with grass and other material of cake shed and soil upto 10-15cm. Spread cow dung manure up to 15-20 cm leave it for one to two month. NEXT

13. B. Farm Slurry Organic Manure : An Overview A mixture of water and animal waste used as fertilizer. Farm slurry is produced at dairy farm at larger scale in rainy season. It is highly nutritive for the plants. Click here to go back at slide 8

14. 2. Green Manures Organic Manure : An Overview Green manure is a type of cover crop grown primarily to add nutrients and organic matter to the soil. They are grown for the purpose of plowing them, thus increasing fertility through the incorporation of nutrients and organic matter into the soil.

15. Benefits of Green Manure Crops Organic Manure : An Overview Green manure crops provide a habitat for pollinators and other beneficial insects. Green manures, in the case of legumes, fix nitrogen and contribute to farm nitrogen needs. It protect and enhance the soil’s biological activity by providing nutrition for the soil organism. It aerates the soil, consequently improving the soil structure. Green manure crops cover the soil in between successive grain crops, thus protecting the soil against wind and water erosion. Green manure crops reduce soil compaction. Click here to go back
