Herbicide molecules must be free from binding to soil particles or organic matter for soil microorganisms to degrade. 3. Most herbicide molecules are more tightly adsorbed to soil particles in dry soils than moist soils. 4. Chemical degradation of herbicides in soil is affected by soil pH. Acid hydrolysis nearly ceases at soil pH above 6.8.
