Abstract:
Soil fertility is one of the crucial factors which maintain soil production and productivity. A special variability in nutrients through a field can be detected using tools such as soil testing. In order to do that, monitoring work regarding soil fertility inventory research was carried out in the Aurai and Katra block in the Muzaffarpur district of Bihar using GPS and Geographic Information Systems (GIS). A total of 40 (forty) geo-referenced composite soil samples from a depth of 0-20 cm were collected from the various locations of the blocks using a GPS instrument. These soil samples were processed in the laboratory and soil attributes were analyzed prescribed using standard methods of procedures. Based on obtained data regarding soil parameters, a soil map thematic layers were created for block boundaries. Soil fertility maps were created by superimposing block unit polygons and the base map using the standard ordinary Kriging interpolation method. The results indicated that the majority of the soils belong to moderately alkaline in reaction. Soil organic matter values also obtained low to medium in a majority of the soils whereas available nitrogen, phosphorus, and potassium were recorded low in the blocks. In the case of micronutrients, value showed below critical limits.
