Research Abstract

The purpose of the study was to evaluate the soil-allelopathic activity in different soils under asparagus cultivation, while focusing on expression of injury by continuous cropping with the same cultivar. Moreover, this study was elucidated adsorption duration of activated carbon, which can easily absorb allelochemicals present in the soil, while associated with changes in the soil microflora. As a result, the effect of and degree of soil-allelopathic activity by application of activated carbon differs depending on the soil properties. When the application became collateral for the increase in soil microorganisms phase, the effect of adsorption duration of activated carbon would be sustained by desorption action of allelochemicals adsorbed to the activated carbon with the activity of soil microorganisms.
