| Research Abstract |
In the sloping upland, we spread the animal surrey, and investigated the movement of the soil water, runoff water and respective ions after the rain-fall.
The resulst have been summarized as follows.
(1) The rain-fall in the sloping upland, at fast, the soil water potential increased in the low regions, and secondly in the high regions.
(2) The runoff percentages were in range of 20-50 percentages.
(3) The movements of K ion was the most remarkable, Nitric acid was evident and ammonia nitrogen was apparent.
(4) All salts in the runoff of the rain were under one percentage.
