Organic (natural) fertilizers have many benefits for the soil and crop production. unlike chemical (inorganic) fertilizers, organic fertilizers reduce acidity in the soil and do not cause leaching. they do not kill beneficial microorganisms in the soil. organic fertilizers also help improve the structure of the soil including the circulation of air, which sustains beneficial microorganisms that help release nutrients to the soil.
the major nutrient that crops such as maize require is nitrogen (n), phosphorus (p) and potassium (k). apart from these, growing crops also require micro-nutrients such as copper (cu), manganese (mn), magnesium (mg), iron (fe), calcium (ca) and sulphur (s).
natural (organic) fertilizers have immense benefits for the soil and crop production. they add soil organic matter, improve soil structure and preserve essential nutrients that crops need in order to grow well
