Abstract

This study aims to recommend fertilization based on the nutrient status of N and K in rainfed rice fields; therefore, it is necessary to conduct a soil analysis to formulate fertilizer recommendations based on the nutrient status of N and K. This research was carried out in Bombanon Village, Mantoh District in July 2021. The chemical properties of the soil analyzed were N (Kjeldahl) and K (HCl25%). The result of soil analysis then matched with the PPT criteria for soil chemical properties status and Balitbangtan guidelines of N and P fertilization for rice crops. The results showed that the N contents at T1 and T3 were low, whereas T2 had a moderate N content. K content at the entire sampling sites were considered moderate. This study recommended N and K fertilization of 275 kg/ha and 50 kg/ha of urea and KCl, respectively, without returning straw.
