In 1988 an experiment was established to stimulate the effect of windthrow on low- and high-productivity forest types in coastal British Columbia. It was hypothesized that site productivity may be improved by mixing the upper 1 m of the organic matter and mineral soil. Results of this study indicated that soil mixing slightly increased soil pH and temperature on both forest types after 2 and 5 years, decreased all soil nutrient availability indices on the high productivity type after 2 years, but resulted in no difference from the control after 5 years, and decreased microbial activity and cellulose loss rate and most soil nutrient availability indices on the low-productivity type after 2 an..View full abstract
