Land cultivated for agriculture has different levels of fertility. Proper soil management is an important factor in determining the growth and yield of plants to be cultivated. The purpose of this study is to identify the rice field fertility variables, conduct an evaluation, and study alternative management according to the soil fertility status. The assessment was carried out in January - March 2020, sampling was carried out in Tebing Kaning Village and soil analysis was carried out at the Bengkulu AIAT Testing Laboratory. The methodology used includes: preparation, implementation of soil sampling, laboratory analysis, and preparation of applicable technology recommendations. In practice, individual soil sampling is used as a composite soil sample, 1 composite soil sample consisting of 10-15 individual soil samples. The number of composite soil samples taken were 10 composite soil samples. Soil analysis data were assessed as CEC, C-Organic, Base Saturation, P-total, K-total, and pH H2O. Based on the results of the analysis, the rice fields of Tebing Kaning Village are divided into 2 fertility classes. Block I, III, and IV with 3 dividers (K-total, CEC, and KB), and Block II with 4 boundaries (C-Organic, K-total, CEC, and KB). The alternative management that needs to be done is to return the straw to the paddy fields in blocks I, III, and IV and the addition of organic matter in block II.
