Soil Nutrient Variability Mapping Using Geospatial Techniques for Sustainable Agriculture in Chodavaram Mandal, Anakapalli District, A.P, India

Agricultural plays a vital role in a farming country's economic development of food security. However, the farming sector is going through a difficult phase due to a lack of awareness of farming activities in India. Sometimes, in most cases, the farmers are unaware of the suitable crops according to their soil quality and structure. The system considers various parameters such as weather forecast and soil condition and gives the best crop ideal for cultivation. Soil nutrient availability is a critical factor influencing crop productivity. This study aims to analyze the spatial distribution of soil nutrients potassium (K), nitrogen (N), phosphorus (P), pH, electrical conductivity (EC), and organic carbon (OC) using geospatial techniques. Spatial interpolation methods were applied to generate detailed nutrient maps and field soil sampling from 66 locations. The results provide insights into nutrient variability and recommend sustainable agricultural practices.
