Abstract: The use of inorganic pesticides result in residues of pesticides in the environment. Mojogedang is an area that has implemented a system of organic farming but also there are farmers who apply chemical pesticides. Pesticides are commonly used by farmers in Mojogedang causing residues, such as organophosphate. Organophosphates contains the active ingredient with a relatively long persistence in the environment and dangerous that it needs a study to investigate the organophosphate residues. The aims of this research to study the level of organophosphate residue and their exposure to soil properties in a variety of land uses in Mojogedang (paddy field, dryland, community forest). This study to analize organic-C, pH, soil texture, total microbia and organophosphate residues including diazinon, parathion, profenofos, ethion, chlorpyrifos, malathion. Data was analized statistically using correlation analysis. Results of this study show that all residue consentration of organophosphate residues active ingredients in organic paddy field soil, inorganic paddy field soil, dryland soil, community forest soil less than maximum residue limits (MRL) 0,05 mg/kg. Residue levels of horticultural dryland with profenofos active ingredient more than MRL (62,060 mg/kg) while the other active ingredient less than MRL. Soil texture is a soil property which closely correlate with organophosphate residues in the soil (sand fraction r = -0,601, dust fraction r = -0,658, clay fraction = -0,509).
