A Study of Erosion Control by means of Crop Management : I. Potato cropping affecting the water-and soil-losses : II. Asparagus cropping affecting the water-and soil-losses

Abstract

1. It was evidently showed that the contour albernative cropping of potato with sugar beet or oat and informal intercropping by oat and small ditch which is set with 5-10 meters interval along contour were all effective for erosion control on the field, potato harvested. 2. For asparagus field it was evident that the mulching by green harvested oat and intercropping by rape were effective for erosion control after harvesting and on the other hand, mulching by bamboo grass, grass and oat straw were effective during harvesting of asparagus.
