dc.description.abstractA field experiment was conducted on “Study of physico-chemical and nutrient stoichiometry of soil under Agri-horti system” during the year 2021-22 at agroforestry farm, , RGSC, Banaras Hindu University, Mirjapur. The experiment was executed with two agroforestry systems viz. custard apple based Agri-horti system and guava based Agri-horti system with three times replicated in a Randomized Block Design (RBD) factorial. For the estimation of soil physicochemical properties (BD, PD, pH, EC, SOC, available N, P, K, Fe, Zn), soil samples were collected from 0-15 cm, 15-30 cm, 30-45 cm, 45-60 cm and 60-75 cm depth. The C sequestration, C credit and stoichiometry of NPK was calculated at different soil depths. Above and below-ground biomass of trees was recorded in the two Agri-horti systems.Physico-chemical proparties of soil varied with agri-horti system and depth of soil the maximum bulk density, partical density pH was recorded with guava based agri-horti system, however porosity, EC and soil organic carbon was recorded maximum with custard apple based agri-horti system. Bulk density, particle density,pH, increases with increasing depth of soil.HoweverEC and soil organic carbon decreases with depth.Nutrient content was recorded maximum with guava based agri-horti system. Further, the nutrient content was decreased with depth of soil at each agri-horti system.The N:P:K stoichiometry recorded higher with custard apple based agri-horti system. Further, regardless of system, the N:P:K ratio decreases with depth of soil.en_US
