The organic acids, formic, acetic, protionic, and butyric acids when applied at 0.5 and at 1.0 mmole/100 g soil to neutral Philippine soils, retarded rice growth. Acids with higher molecular weight had more distinct retarding effects. Soil with fresh green manure temporarily produced fairly high amounts of acetic, propionic, and butyric acid, and in submerged soils they occurred within 2 weeks. Acetic acid was the major organic acid produced. The cause of the retardation of rice plant in the soil amended with green manure was considered to be due to the organic acids produced in the soil. The growth retardation of rice plant was prevented by the addition of ammonium sulfate but not by the addition of ammonium chloride. We found much less propionic and butyric acid in the soils with ammonium sulfate.
