Assessment of Soil Fertility Status in Palghar District of Maharashtra through Geospatial Techniques

Abstract

Georeferenced surface soil samples from Six (06) tehsils were delineated using stratified random soil sampling method by using (GPS) and analyze at AICRP of Micro and Secondary Nutrients and Pollutant Elements in Soils and Plant under Department of Soil Science, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra to assess the chemical properties, major and micronutrients status in soils of Palghar district in the year 2021-2022 of one hundred and seventy nine (179) samples at the depth of (0-20 cm) were collected across the Palghar district of Maharashtra at 5 kms grid and analysed in the laboratory. The results revealed that pH, EC, CaCO3 and organic carbon of soils collected across different tehsils of Palghar district varies from 5.49 to 8.16,0.05 to 1.29 dS m-1,0.63 to 13.25 % and 2.20 to 10.7 g kg-1. Whereas available S in soils ranging 7.26 to 31.89 mg Kg-1. The DTPA -Zn, Fe, Cu and Mn in soil of Palghar district ranged from 0.35 to 7.14 mg Kg-1 ,5.42 to 77.32 mg Kg-1 ,0.88 to 14.88 mg Kg-1 and 8.53 to 79.84 mg Kg-1 respectively. The CaCl2-B in soils of all tehsils ranging 0.23 to 0.69 mg Kg-1. The results were clearly showed a large variation in physio-chemical properties of soil across the Palghar district with low nutrient indices to boron (1.39), medium for Sulphur (1.75) high for zinc (2.37), iron (2.81), copper (3.0) and manganese (3.0).
