Understanding phosphorus dynamics and uptake in diverse soils of Indo-Gangetic Plains of India.

ABSTRACT: Phosphorus (P) is a critical macronutrient governing crop productivity, yet its availability in soils is limited by soil physico-chemical properties and interactions with other nutrients. The present study investigated phosphorus dynamics and uptake by wheat grown on twenty-five soils collected from different locations across the Indo-Gangetic Plains (IGP) of India. The soils exhibited wide variation in texture, pH (4.3-9.1), organic carbon (0.14-0.9%), and available macro and micro nutrients. Phosphate ion concentration and phosphate potential varied significantly (p < 0.05), reflecting contrasting P-supplying capacities. A pot experiment was conducted with wheat under control (no P) and 100% recommended P fertilizer application. Significant variation (p < 0.05) was observed in dry matter
