ABSTRACT

The Effects of Chemical Fertilizers and organic manure on soil fertility focuses primarily on the behavior of nitrogen (N) and phosphorus (P) in soil because these two nutrients are the main nutrients that limit crop yields and they are also the nutrients of particular concern for environmental quality. Besides, potassium (K), sulfur (S), macronutrients (primary and secondary), micronutrient and other elements, salts, and sodium, soil pH, EC. CEC and organic matter are covered. Organic fertilizer improves physical and biological activities of soil but they have comparatively low in nutrient content, so larger quantity is required for plant growth. However, inorganic fertilizer is usually immediately and fast containing all necessary nutrients that are directly accessible for plants. But continuous use of inorganic fertilizers alone causes soil organic matter degradation, soil acidity, and environmental pollution. So the combined application of inorganic fertilizer and organic manure has an alternative system for the sustainable and cost-effective management of soil fertility. The objective of the present review is to assess the effect of long-term chemical fertilizers and organic manure on soil fertility. The study revealed that the appropriate application of inorganic fertilizers along with organic manure increases soil fertility than the values obtained by organic or inorganic fertilizers separately.
