Fertilizer is a man-made inorganic salt whereas manure is a natural substance obtained by decomposition.

Manure is a natural substance obtained by decomposition, and it is different from fertilizers, which are typically synthetic and inorganic compounds. Manure is the organic matter that results from the decomposition of animal waste, plant residues, or both. It contains various nutrients like nitrogen, phosphorus, and potassium, which are essential for plant growth. Additionally, manure helps to improve soil structure, water-holding capacity, and soil fertility.

On the other hand, fertilizers are chemical compounds manufactured by industrial processes, and they are not derived from natural sources. They usually contain high concentrations of nitrogen, phosphorus, and potassium, which are essential nutrients for plants, but they lack other beneficial organic compounds and micronutrients that are present in manure. While fertilizers can provide plants with essential nutrients to enhance growth, overuse can lead to soil degradation, reduced soil fertility, and pollution of groundwater and surface water resources.
