Studies on the Relation of Crops and Cropping System to Soil Erosion : (VI) Effects of vegetative covers on erosion mechanism

Abstract

Experiments were carried out on the volcanic ash soil at Kuriyagawa under heavy rain, Sep. 18, 1954. (total rainfall-11.1 mm, maximum intensity-8.0 mm per 10 minutes) 1. Remarkable relations were found between the amount of soil loss and the foliage cover of crop canopies, between the foliage cover of crop canopies and the rate of control in splash soils, between the rate of splash soils and the amount of soil loss, and between the amount of water loss and the rate of rainfall interception, respectively. 2. On the other hand, there were found no clear relation beeween the amount of soil loss and the rate of rainfall interception, between the rate of rainfall interception and the foliage cover of crop canopies, and between the rate of control in splash soils and the amount of water loss.
