The present study was undertaken during Kharif 2017-18 to assess chemical properties of soil under different land use systems in a Mollisol. The study area was located at Norman E. Borlaug Crop Research Centre, G. B. Pant University of Agriculture and Technology, Pantnagar. The land use systems selected for study were rice–wheat–green gram, rice–pea(vegetable)-maize, rice-potato –okra, rice–berseem + oat + mustard(fodder)-maize + cowpea(fodder), maize–wheat–cowpea, sorghum(fodder)-yellow sarson-black gram, guava + lemon, poplar + turmeric, eucalyptus + turmeric and fallow(uncultivated land). Soil samples were taken from 0-20cm depth and analyzed for the various chemical properties. Soil pH (H2O) varied from 7.38 to 7.49, electrical conductivity varied from 0.249 to 0.326 dSm-1 and CEC varied from 22.21 to 36.51 C mol(p+) kg-1 soil. Soil organic carbon content ranged from 0.54 to 1.52 percent. Available soil nitrogen content varied from 148.02 to 311.09 kg ha-1, available soil phosphorus from 14.29 to 25.97 kg ha-1 and available soil potassium from 153.66 to 259.62 kg ha-1. Available sulphur varied from 16.99 to 32.03 mg kg-1. Among micronutrients, available zinc content in soil varied from 0.77 to 2.16 mg kg-1, available copper content in soil from 3.83 to 5.89 mg kg-1, available iron content in soil from 14.07 to 33.84 mg kg-1 and available Mn content in soil from 5.93 to 7.89 mg kg-1. Results indicated that with respect to chemical properties of soil agroforestry based systems were found superior followed by field crops, horticultural crops and the fallow (uncultivated land).
