Abstract
The effect of nitrogen compounds and moisture regimes on the inhibition of the biological hydrolysis of parathion in rice straw-amended soil under flooded conditions was studied. Single applications of rice straw, potassium nitrate or ammonium sulphate to the flooded soil, inoculated with parathion-hydrolysing enrichment culture, inhibited the hydrolysis of the insecticide; the inhibition was reversed, however, in combined applications of rice straw with potassium nitrate or with ammonium sulphate. Aqueous extracts of rice straw-amended soils incubated under flooded undisturbed conditions as well as at 100% moisture inhibited the hydrolysis. The inhibitory factor was not formed in rice straw-amended flooded soils incubated at 50 and 75% moisture levels.
