Abstract
Nutrients available in the soil of rice fields are not always uniform. The study aims to determine the variability of Nitrogen, Phosphorus and Potassium (NPK) contain in the soil. Research was conducted in Wotan, Bener, Sragen regency. Determination of NPK was done using a modified device of soil test. A paddy field was set up into 50 plots measuring 10 x 6 m2, and soil samples were taken from each plot. The NPK test results were mapped. Map of NPK distribution status of rice field show that the availability of NPK in the soil were uniform. N level was low, P and K levels were high in the soil. Urea fertilizer recommendations were required at low N plot was 300 kg N / ha. SP-36 fertilizer recommendation for high P plot was 75 kg / ha. Plant height, number of leaves, number of tillers per hill, dry weight of plant per hill in applying NPK compound fertilizer in farmer dose with VRA was significantly higher than application of URA. Recommendations of KCl for high K plot was 75 kg / ha.
