Spatial Analysis of Soil Available Potassium and Plant Brix Content for Site Specific Nutrient Management in Sugarcane

نویسندگان

چکیده

There has been a tendency of decreasing sugarcane productivity (Saccharum officinarum Linn) in Indonesia due to poor soil available potassium. also evidence that potassium relates directly condition. For this reason, the management engaging Site Specific Nutrient Management (SSNM) must be pursued. The first and most important stage SSNM is assessing variability, which can used recommend particular fertilizer. This research’s main aim assess variability Potassium Brix content for uses (K) fertilizer recommendation. methodology research collecting data field, analyzing with Geographical Information Systems (GIS) using Kriging techniques, developing site-specific K prescription map. results show (1) spatial analysis assisted map sugarcane; (2) spatially, area classified into three classes (low, medium, high) recommendation 300 kg/ha (low), 200 (medium) 0 (high) respectively. suggest provide whole specific picture studied, beneficial SSNM.
