我们用1%和2%浓度的牛粪处理了印度北方邦六个不同地区的土样,并把它们培养15天和30天.在实验室里,我们测定了自然状态的及处理过的土壤侵蚀常数.当把牛粪在土壤中腐烂30天时,发现牛粪对控制土壤侵蚀是有效的.培养十五天时,提高了许多土壤的侵蚀,这可能是由于二氧化碳的产生以及由此造成土壤PH值的下降所致.在减慢土壤侵蚀上,发现2%浓度刚好优于1%浓度的.我们也观察到,牛粪对具有高侵蚀系数的轻质土壤有更大的效结.
We treated soil samples from six different areas of Uttar Pradesh in India at cow’s dung concentrations of 1% and 2% and cultured them for 15 days and 30 days. In the laboratory, we measured both natural and treated soil Erosion Constants Cow dung was found to be effective in controlling soil erosion when cow dung was decayed in soil for 30 days, and many soil erosion was increased after 15 days of cultivation, possibly due to the production of carbon dioxide and the resulting soil pH In the slowing down of soil erosion, 2% was found to be just above 1% concentration.We also observed that cow dung had greater effect on light soil with high erosion coefficient.
