Agriculture is a vital sector that sustains human life and ensures food security. In recent years, however, there has been a growing concern about the impact of industrial farming practices on the environment, including soil degradation and pollution. As a result, there has been a renewed interest in sustainable agriculture practices promoting soil health and fertility while reducing synthetic fertilizers and pesticides. One such practice is the use of farmyard manure.
Farmyard manure, also known as barnyard manure or simply manure, is a type of organic fertilizer used for centuries in agriculture. It is made up of animal waste such as cow dung, horse manure, poultry litter, pig manure, and plant residues such as straw and hay. The organic matter in farmyard manure decomposes slowly, releasing essential nutrients such as nitrogen, phosphorus, and potassium into the soil. This makes it an excellent source of plant nutrients and a natural way to improve soil fertility.
