土壤侵蚀在坦桑尼亚是全国性的问题.对侵蚀极为敏感是由于:(1)高地降雨极多并很经常.这些高地(其中基里曼加罗、南方高地、鸟山巴拉斯〕的人口稠密,也加重了侵蚀危害.(2) 中部高地广泛地过度放牧.侵蚀耗竭了肥沃的表土,带走了大量的有机质.在中部高源,几乎全靠有机质防上养分滤掉,而有机质本身也是养分的来源.几年前在坦桑尼亚西部对花岗岩母质生成土壤自由排水的研究,确定有机质与作物养分很高显著有关.
Soil erosion is a national problem in Tanzania, and is extremely sensitive to erosion due to: (1) very high and frequent rainfall in the highlands (densely populated in these highlands (Kirimanegal, Southern Highlands, (2) over-grazing extensively in the central highlands, erosion depleted the fertile topsoil and removed large amounts of organic matter, and in the central high source almost nutrient-rich organic matter was filtered out and the organic matter itself The source of nutrients. A few years ago in western Tanzania, granite parent material to generate free drainage of soil studies to determine the organic matter and crop nutrients are significantly higher.
