Assessment of Soil Fertility Status in Paroo and Saraiyan Blocks of Muzaffarpur District of Bihar Using GPS and GIS

The experiment was conducted during 2019‒21 at Paroo and Saraiya blocks of Muzaffarpur district Bihar, India to identify the nutrients status for crop management. Soil fertility inventory research carried out in these two identified (Paroo Saraiyan) generation thematic soil map. For nutrient assessment altogether 40 (forty) geo-referenced composite samples were collected from various locations studied area using a hand-held GARMIN GPS device. processed used analysis parameters by prescribed standard methods. maps created ArcGIS 10.4.1 software employing Inverse Distance Weighted (IDW) interpolation techniques. results clearly indicated that soils pH alkaline nature ranges 7.4‒9.5. mean value organic matter (0.55%) potassium (150 250 kg ha-1) found be low medium whereas, available nitrogen (119.9 319.1 90% deficient, however, phosphorus (4.34 18.4 ha-1), sulphur recorded blocks. However, most sample micronutrients like copper (0.23 1.07 mg kg-1) Iron (1.64 13.2 ppm) showed above critical limits while manganese, zinc deficiency occurred wide area. intensive cropping system imbalanced use chemical fertilizer is degrading quality study
