Studies on Depth Wise Distribution of Available Nutrients of Soil under Different Land Use Planning of Kanpur Nagar (U. P.), India

Abstract

An investigation was carried out during 2021-22 at various land use planning of Kanpur Nagar (U.P.) to evaluate the availability of nutrients effect of various land use planning on soil. The 504 representative soil samples with 3 depths viz. 0-15, 15-30, and 30-60 cm soil samples were taken with manually driven post hole auger and processed for soil analysis from different land use planning of Kanpur Nagar. Available nitrogen, phosphorus, potassium, Sulphur, micro nutrients (Fe, Cu, Mn and Zn) and notable available Nitrogen in different lands low in ranged from 112.4 – 199.3 kg ha-1. The Phosphorus availability was found in ranged from 8.40 - 19.90 kg ha-1, while Potassium was found in ranged from 111.30 - 192.10 kg ha-1. However the availability of Sulphur, was found in ranged from 7.40 - 23.80 mg kg-1 and the availability of micro nutrients like - available Iron ranged from 4.34- 16.9 mg kg-1, available Manganese ranged from 1.10- 10.9 mg kg-1, available Copper ranged from 0.47 – 3.76 mg kg-1, and available Zinc ranged from 0.33- 2.54 mg kg-1.
