EROSION - ITS EFFECT ON SOIL PROPERTIES, PRODUCTIVITY AND PROFIT ISSUED: REVISED: L. W. Murdock and W.W. Frye Department of Agronomy Almost all people recognize that erosion is harmful, but few realize how harmful. Certainly, there are costs to society for clean-up and repair from soil and its constituents polluting the water and air. Soil erosion is a major environmental issue because it can lead to water pollution. But did you know that soil erosion also can seriously impair crop productivity? Most agriculture activities, especially on sloping landscapes, increase the potential for soil erosion. When soil erosion is severe, soil erodes faster than it can be renewed. For most areas of Iowa, the loss of 1 inch .   Abstract. Soil erosion and the effects of soil erosion on crop productivity have become emotional issues and have attracted the attention of agriculturists, environmentalists, and the public in general. In spite of heavy investments in research and development, the global rates of accelerated erosion are now presumbly higher than ever by: Soil erosion is the biggest threat to soil fertility and productivity, as it removes organic matter and important nutrients and prevents vegetation growth, which negatively affects overall.

Soil erosion is a gradual process that occurs when the impact of water or wind detaches and removes soil particles, causing the soil to deteriorate. Soil deterioration and low water quality due to erosion and surface runoff have become severe problems worldwide. The problem may become so severe that the land can no longer be cultivated and must be abandoned.   P. Crosson, Soil Erosion and Its On-farm Productivity Consequences: What Do We Know? (Resources for the Future, Washington, DC, ). S. J. The consequences of soil erosion are primarily centered on reduced agricultural productivity as well as soil quality. Water ways may also be blocked, and it may affect water quality. This means most of the environmental problems the world face today arises from soil erosion. The effects of soil erosion include. Effects of Soil Erosion. The major effects of soil erosion include: Loss of Arable Land. Soil erosion removes the top fertile layer of the soil. This layer is rich in the essential nutrients required by the plants and the soil. The degraded soil does not support crop production and leads to low crop productivity. Clogging of Waterways.

The agricultural plants that often replace the trees cannot hold onto the soil and many of these plants, such as coffee, cotton, palm oil, soybean and wheat, can actually worsen soil erosion. And as land loses its fertile soil, agricultural producers move on, clear more forest and continue the cycle of soil loss. Excessive (or accelerated) erosion causes both "on-site" and "off-site" problems. On-site impacts include decreases in agricultural productivity and (on natural landscapes) ecological collapse, both because of loss of the nutrient-rich upper soil layers. In some cases, the eventual end result is desertification. Soil erosion reduces cropland productivity and contributes to the pollution of adjacent watercourses, wetlands and lakes. Soil erosion can be a slow process that continues relatively unnoticed or can occur at an alarming rate, causing serious loss of topsoil. soil erosion, deforestation and rural livelihoods in thecentral rift valley area of ethiopia: a case study in the denku micro-watershed oromia region.
