A Review of Impact on Organic Manures, Fertilizers and their Incorporation on Soil Chemical Properties, NPK Fractions, Soil Enzymes, and Crop Productivity

Continuous indiscriminate use of chemical fertilizers alone can lead to plant uptake nutritional imbalances in soil. This method of handling non-judicious nutrients may also have detrimental impacts on soil's physical, chemical and microbiological properties. Only when the soil has a favorable physical, chemical, and microbiological condition is sustainable crop production possible. In this context, this paper provides a brief overview of the literature on the impact of organic manure, chemical fertilizers and their incorporation on soil chemical properties, soil nutrient distribution, microbiological properties and crop productivity.
