Abstract:Previously, horizontal-ridge system has been shown effective in reducing soil erosion. But, it could cause water logging, which is detrimental to crop growth and yield. To solve this problem, drainage canal establishment might be reasonable. However, the evidence remains scarce. In this study, effect of drainage canal intervals on the volume of runoff, soil loss, and nutrient loss (N-total and P-total) were investigated. There were 4 drainage canal intervals applied to the 12 targeted plots (each sized 3 m x 3… Show more
