Abstract
This research is a study of the effect of the release of nitrogen from compost using more rice. Sweet as, for example, the plants and the phot series Sentinel testing ground. In this test plan, test (Randomized Complete Block, RCB) divided into six series of experimental trials is 4 by soil samples analyzed storage from planting until the am 60 day collected the soil analyzed every 15 days to analyze, find the อินทรีย object in the soil (Organic meter, OM) as the acid-alkaline (pH) electrical values (Electrical conductivity, EC). Quantity aemmoniam (NH4 +) and Chennai (NO3-), in which the great Tequila from the test results, it was found that the third set of experiments is the ratio of 0.5 kg compost/soil more 10 kg.
