Nutrient reclamation in a few districts of Rajasthan through organic farming

Urbanization and Industrialization have led to a considerable increase in the contaminants in the soil. Soil can bind various chemicals, so it is a major reservoir for such contaminants. In this study, focus is made on the techniques through which we can reduce the concentration of pollutants, improve soil health, and reduce the toxicity of the Alluvial/Black soils found in Jaipur, Kota, Bundi districts of Rajasthan. Geographically, Rajasthan is the largest state in the country having varied topography where soils differ in quality depending on the organic matter present, physical structure, local climatic variations, the crop rotation cycle i.e., followed, availability of moisture etc. The soil’s capacity to carry nutrients varies not only within the district but also from village to village and even farm to farm. Soils in Rajasthan have low microbial activities and poor soil organic carbon content and because of that, about 75% of soils of the state are not in good health. Nitrogen, Phosphorous, Sulphur, Zinc, and Iron etc. are quite deficient. Several key issues of soil degradation with practical methods to improve soil quality and rehabilitation by assessing the toxicity are emphasized.
