The present study was focused on the analysis of physical and chemical properties of soil, under different agroforestry models. The study was conducted during 2016-2017 in the field of Indira Gandhi National Tribal University, Amarkantak, MP and during the study the soil sample was collected from different agroforestry model at the depth of 0-20 cm and 20-40 cm with the help of soil auger. Result reveals that the status of pH and EC ranged from 5.79 to 6.12 and 108.5µs to 233 µs, respectively, at 0-20 cm depth and at 20-40 cm depth, from all the Agroforestry Models. The Total Dissolving Salt (TDS) concentration ranged between 142 ppm to 166 ppm at 0-20 cm and 77.3 ppm to 162 ppm at 20-40 cm and salt concentration value varies from 57.1 ppm to 115 ppm in various Agroforestry Models. The Nitrogen and Phosphorus contents was observed in Agroforestry Model I (D. Sisso + Aonla + Wheat) that is 420 and 22.5kg ha-1 at the depth of 0-20 cm and the highest Potassium was observed in Agroforestry Model II (Teak + Guava + Soybean ) at the depth of 20-40 cm. The status of Nitrogen, Phosphorus and Potassium show mixed trends regarding the cultivation practices and depth of soil in case of model I and model II but in case of model III it was shows a significant difference between the model I and model II. The present study recommended that incorporation of at least one component belonging to leguminous family in agroforestry practices are highly preferable and beneficial which show better result regarding the health and fertility status of soil.
