Understanding variability in crop response to fertilizer and amendments in sub-S
A chemical fertilizer is defined as any inorganic material of wholly or partially synthetic origin that is added to soil to sustain plant growth. Manure is an organic matter derived from the solid animal wastes, used to improve the soil quality and increase the yield of healthy crops. Most of the manure within the irrigation scheme comes from decomposed livestock and crop waste. Manure is used because its cost effective and rich in minerals like nitrogen, phosphorus, and potassium. Manure is also rich in organic matter and humus and thus improves the soil fertility for plant production. Manure improve soil fertility and allow chemical fertilizers reduction.
