The Role of Digital Soil Information in Assisting Precision Soil Management

Soil information is the basis for site-specific management of soils. The study aimed to digitize soil and classify it into mapping units (SMUs) using geostatistics. area was grouped 12 SMUs, or zones. pH soils ranged from 7.3 in SMU2 8.6 SMU5. Most SMUs exhibited low total nitrogen (TN) that could be attributed very organic carbon (SOC) Available phosphorus (AvP) all units. exchangeable K varied between 0.12 cmol(+) kg?1 (SMU7) 0.95 (SMU10). SMU12 identified as marginally sodic at a high risk developing severe alkalinity unless possible measures are implemented. Our findings show lack causes an imbalance requirements external nutrient inputs, negatively affecting crop production. Therefore, high-resolution digital can assist application nutrients amendments based on spatial variability line with requirements.
