SPATIAL VARIABILITY MAPPING OF MACRONUTRIENTS ACROSS AMRELI AND KACHCHH DISTRICT, GUJARAT

Kartik Thakor, Sujay Dutta

Abstract :

In the era of modern Indian agriculture macronutrients are important nutrient elements for growth and productivity of the crops. Soil macronutrients datasets of Amreli (265 samples) and Kachchh district (144 samples) were obtained in spreadsheet format from Anand Agriculture University, Gujarat. Further, generated spatial distribution maps of macronutrients (viz. phosphorus, potassium and sulphur) using IDW interpolation technique of GIS. Range and average variability status also estimated using Exploratory Spatial Data Analysis tool of ArcGIS10. Soil Nutrients Indices evaluate fertility class of soil. The results of SNI revealed low fertility class of phosphorus and sulphur across Amreli district while across Kachchh district SNI revealed medium fertility class of phosphorus &sulphur. Across Amreli district SNI revealed medium fertility class of available potassium while Across Kachchh district SNI revealed higher fertility class of available potassium. On the basis of spatial distribution maps and SNI recommended fertilizer doses for nutrients management.
