Abstract

Rice is one of the primary commodities cultivated by Indonesian farmers such as in the Tuban Regency. To increase rice productivity is critically important to evaluate the condition of soil fertility. Soil fertility assessment is needed to determine balanced fertilization. Balanced fertilization is critically essential in the production process. This research analysis method used the SOFIX database. The soil samples were carried out in rice fields based in one of the agriculture-integrated areas in the Tuban Regency. The results show that the soil had a deficient bacteria number and low nitrogen and phosphate circulation activities. On the other hand, all parameters such as total carbon, total potassium, total nitrogen, and total phosphorous also tend to be low. Therefore, applying balanced fertilization to recover soil fertility. Organic materials used to improve bacterial activities. The results suggest that paddy soil fertility status in Tuban Regency leads to recovery by adding organic materials.
