Applications of pesticides on crop land have been used by soybean land farmer in Jombang, Lamongan and Probolinggo in order to control pest. Pesticide application of soybean land influence physic and chemistry soil, against growth of plant furthermore. This study aimed to identify soil physic and chemistry characteristic on pesticide application of soybean land. This study used sampling purposive method on soybean land in Jombang, Lamongan and Probolinggo District. The data were taken by purposive on pesticide application between pre and post soybean cultivation. Parameters included of soil physic (soil mass, soil porosity, water level, soil texture and determination of soil class), soil chemistry (composition of C-Organic, Total of N, Ratio C/N, P and organic matter). The data were analyzed quantitative and qualitative descriptive. Data analysis showed pesticide application of soybean land in Jombang, Lamongan and Probolinggo included intermediate category with composition 1,19-1,25 g cm and contain of particle type were 2,30-2,38 g cm , soil porosity accord to ideal land criteria 46,08-49,30%, water level were higher than free capacity limit (0,33 pF) with classification water available, soil texture on T2 class were slightly smooth, at every location C-Organic compositions included low category (0,58-0,94%), low total of N (0,090,15%), C/N ratio in low category up to 6-9, P total were varied, from low (J3 dan J2) were 11,90 mgkg and 11,94 mgkg, intermediate (J1, L3, P2 dan P3) up to 19,72-22,59 mgkg, another three locations L1, L2, and P1 included of high category, were 36,82-38,48 mgkg. Organic matters composition. Keywords— soil physic and chemistry characteristics, pesticide, soybean land, Jombang, Lamongan and Probolinggo.
