Abstract
The soil fertility capability (SFM) classification system consists of three categories, namely Type (0-20 cm layer); Sub-type (20-50 cm layer) and Unit or condition modifiers related to soil physical characteristics, soil reactions and soil mineralogy. Soil fertility is the potential of soil to provide sufficient nutrients in an available and balanced form to ensure optimum plant growth and production. The purpose of the study was to identify the class and status of fertility in the land units in Wonosalam District. The study used the land survey method, soil samples were taken purposive sampling at depths of 0-20 and 20-40 obtained 10 sampling points, KKK Classification Table to classify soil based on fertility constraints. Using the matching method to determine soil fertility constraints and soil fertility status using technical guidelines for soil fertility evaluation. The results showed that the fertility constraints found were C which indicates that it has a clay texture and LC which indicates that it has a clay texture, LLk indicates that the soil in the topsoil and sub soil has a texture with clay content <35%, Ck indicates that it has a clay texture and has low potassium levels and low soil fertility at all sampling points due to limiting factors, namely. organic C concentration, Available P and Base Saturation. Key words: classification, fertility, soil, wonosalam
