Study GPS based soil fertility status of Tendukheda block of Narsinghpur district in central India

Abstract

Study was undertaken to assess the soil nutrients status of Tendukheda Block of Narsinghpur District in Central India using GPS technique. In this study, spatial variability in properties that influence soil fertility such of eight villages of Tendukheda block was studied. Forty Eight (48nos.) soil samples were drawn from 0-20 cm depth. Six soil samples from each village selecting farmers randomly on the basis of land holding having low ( 3 ha) farmer categories applying GPS, and only two soil samples were taken from each category. Soil samples were analyzed for different parameters viz pH, EC, O.C., available N, P, K, S and micronutrients like Zn, Cu, Fe and Mn. The soils of the area are characterized by neutral to alkaline in pH and medium to high in organic carbon content that was ranged from 0.51 to 0.96% with an average of 0.59 percent. The available NPK and S ranged low to medium (202-396 kg ha-1), 9.26-23.44 kg ha-1, 282-759 kg ha-1 and 5.45 to 14.41 mg kg-1 respectively. While micronutrients were reported from 0.19.to 0.69 mg kg-1 Zn, 1.24 to 2.5 mg kg-1 Cu, 4.00 to 6.13 mg kg-1 Fe and 7.70 to 11.75 mg kg-1 Mn. The nutrient index was with organic carbon, nitrogen and zinc while medium with phosphorus sulphur and Iron however, high N.I. was recorded with Cu and Mn content in the surface soil.
