Study on the effect of compost on the biochemical and physical changes for the first year of Mabbon soil series was conducted at Rayong Land Development Station, and soil and water conservation laboratory in 1984. The design of experiment was randomized complete block with 12 treatments and 3 replications. The treatments were 1) no corn planting+none of fertilizers 2) no corn planting+compost 2 tons/rai 3) no corn planting+compost 4 tons/rai 4) no corn planting+compost 6 tons/rai 5) corn planting+none of fertilizers 6) corn planting+compost 2 tons/rai 7) corn planting+compost 4 tons/rai 8) corn planting+compost 6 tons/rai 9) corn planting+chemical 50 kg/rai 10) corn planting+chemical 50 kg/rai+compost 2 tons/rai 11) corn planting+chemical 50 kg/rai+compost 4 tons/rai 12) corn planting+chemical 50 kg/rai+compost 6 tons/rai. The application of compost 2 tons/rai increased more the microbiological population than without compost. The compost enhanced the available nutrient form for crop production. Furthermore, percentage of organic matter, ion concentration and water holding capacity in soil were increased.
