Abstract

Understanding the spatial variability of soil fertility is crucial for effective site-specific nutrient management and making precise fertilizer recommendations. To assess and map the soil fertility status (focusing on NPK) across different blocks of Palwal District, Haryana, this study was conducted using advanced GIS technique. A total of 228 geo-referenced soil samples were collected from the district at a depth of 0-15 cm, using GPS for precise location data. These samples were analysed for nutrient content, and thematic maps were created based on nutrient ratings for available soil NPK. The results of the soil fertility mapping revealed that approximately 64 and 45 per cent of the studied area falls into the high fertility category (PK, respectively), while 3, 24 and 50 per cent is categorized as medium fertility (NPK, respectively). Not a single sample recorded a higher nitrogen status in the district. However, 97, 12 and 5 per cent of the area was identified as having low nutrient availability (NPK, respectively), indicating nutrient deficiency. Based on this comprehensive soil fertility appraisal, a nutrient management plan tailored to the needs of various crops can be developed for each village, ensuring that specific nutrient requirements are met and enabling optimized agricultural practices for improved productivity in the district.
