TL;DR: In this article, the authors survey the Si status of agriculturally important soils of different parts of the country and develop region-specific integrated nutrient management systems that include the Si element.

TL;DR: In this article, the potential of sugar industry by-products, their availability, and use in agricultural production is reviewed, and a large number of research experiments and literatures have been surveyed and critically analyzed for the effect of sugarcane byproducts on crop productivity and soil properties.

TL;DR: Soil and groundwater from long-term (>50 years) tannery effluent irrigated areas of Kanpur were analyzed and significant buildup of heavy metals such as Cr, Ni, Cd, Pb, Zn, and As in the range of 252–972, 23–30, 2.3–14.8, 138–338 and 6.8–11 mg kg−1, respectively in soil was found.

TL;DR: Pigeon pea biochar has the potential to increase spinach yield and reduce cadmium mobility in contaminated sandy soil, and there was a reduction in the diethylene triamine pentaacetic acid (DTPA)-extractable Cadmium in the soil and in transfer coefficient values (soil to plant), as well as its concentrations in spinach leaf and root, indicating that cad mium mobility was decreased.

TL;DR: In this paper, graded doses of hexavalent chromium were applied to a clay loam soil to investigate the impact on carbon (C) mineralization rate and enzymatic activities at various time intervals.
