Abstract
To study metribuzin degradation in soil and the effects of manure amendment on its half life, an experiment was conducted in completely randomized design with factorial arrangement and three replications. Treatments included cattle manure amount at four levels (0, 1, 5 and 10 based on soil percentage weight), and soil incubation periods at 7 levels (0, 2, 4, 8, 16, 36, 64, 90 days). According to the results, average metribuzin degradation was 69.22% in soil without cattle manure amendments and increasing the 1, 5 and 10% manure decreased metribuzin residue by 64.69, 64.42 and 64.91% respectively. Soil incubation period had very significant effect (p
