Status and distribution of soil fertility under different domains of central India

Abstract

In present study GPS based 531 soils samples were collected, analysed in the lab of Department of Soil Science and Agricultural Chemistry Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur during 2018-2020. Data obtained were statistically interpreted. Results suggested that the soils of the domains were found neutral to slightly alkaline in soil reaction, safe in electrical conductivity, high, low, medium and low in Bhopal, Jabalpur Vidisha and Hoshnagabd domains in organic carbon content and non-calcareous nature. Result revealed that the N, P, K and S denoted as low-L medium-M, high-H, and found to be (M-L-H-M); (L-M-H-M); (L-M-H-M); (L-M-M-M); and (L-H-M-M) in Bhopal, Jabalpur Vidisha and Hoshnagabad domains, respectively. However, in AESR10.1 as whole, revealed that organic carbon was found to be medium and macronutrients were analyzed to be L-M-M-M hence the severity of deficiency occurred in the order of N > S > P > K. The results could be used as a basis for site specific fertilization in order to supply the optimum requirements for plant growth.
