What is farm yard manure ?????? Explain briefly
Answers
Answer:
Manures are plant and animal wastes that are used as sources of plant nutrients. They release nutrients after their decomposition. The art of collecting and using wastes from animal, human and vegetable sources for improving crop productivity is as old as agriculture. Manures are the organic materials derived from animal, human and plant residues which contain plant nutrients in complex organic forms. Naturally occurring or synthetic chemicals containing plant nutrients are called fertilizers. Manures with low nutrient, content per unit quantity have longer residual effect besides improving soil physical properties compared to fertilizer with high nutrient content. Major sources of manures are:
Cattle shed wastes-dung, urine and slurry from biogas plants
Human habitation wastes-night soil, human urine, town refuse, sewage, sludge and sullage
Poultry Jitter, droppings of sheep and goat
Slaughterhouse wastes-bone meal, meat meal, blood meal, horn and hoof meal, Fish wastes
Byproducts of agro industries-oil cakes, bagasse and press mud, fruit and vegetable processing wastes etc
Crop wastes-sugarcane trash, stubbles and other related material
Water hyacinth, weeds and tank silt, and
Green manure crops and green leaf manuring material

Answer:
Farmyard manure refers to the decomposed mixture of dung and urine of farm animals along with litter and left over material from roughages or fodder fed to the cattle.
Farmyard manure is a fertilizer composed of waste products, typically dung and urine, produced by farm animals, most commonly cows. The waste products contain a wealth of nutrients, including the extremely important element that plants need—nitrogen.
There isn't an involved process to prepare farmyard manure. All you have to do is collect the cow dung and urine into a layer of even thickness under a simple roof to keep it from getting excessively wet and exposed to pure sunlight. More dung and urine are added along with some water if it gets too dry. The farmyard manure is ready to use on fields as fertilizer in roughly six months.
