The role of GIS and GPS in precision fertilization: Optimizing nutrient management for sustainable cropping

Precision fertilization is a crucial aspect of modern agriculture, enhancing crop productivity while minimizing environmental impact. Geographic Information Systems (GIS) and Global Positioning Systems (GPS) play a vital role in optimizing nutrient management by enabling precise and data-driven decision-making. GPS facilitates accurate field mapping, soil sampling, and variable rate fertilizer application, while GIS integrates spatial data to assess soil variability and optimize fertilizer distribution. These technologies contribute to improved efficiency, cost savings, and sustainability by reducing over-application and nutrient runoff. Despite challenges such as high implementation costs and data complexity, advancements in artificial intelligence, remote sensing, and IoT are further revolutionizing precision fertilization. This article explores the integration of GIS and GPS in nutrient management and their potential to transform sustainable cropping systems.
