Chemical Assessment of Soil Quality of Madhepura District (Bihar): A Review

This review summarises existing knowledge of soil chemical properties in regions geographically and geologically proximate to Madhepura District in Bihar, India. In the fertile Indo-Gangetic Plain, Madhepura shares common soil characteristics with neighboring districts such as Purnea, Samastipur, Muzaffarpur, and Katihar. Studies indicate that these soils are predominantly sandy loam to loam, mildly acidic to slightly alkaline, with low to medium organic carbon and macronutrient levels, particularly nitrogen (N), phosphorus (P), and potassium (K). Given this, it is plausible that soils in Madhepura exhibit similar deficiencies, affecting fertility and crop productivity. This review collates physico-chemical analyses from neighbouring districts, extrapolates potential soil chemistry trends for Madhepura, and outlines strategies for improved soil management tailored to the region. The data collected in this review paper will be used as secondary data, which will be helpful to complete my research work and is also related to the soil quality of Madhepura District, Bihar.
