Soil erosion: effect on soil productivity Integrated

2021-5-6  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 per acre of

"Impact of soil erosion on soil productivity" by Gerald

To understand the effect that soil characteristics have on soil productivity (and the impact of erosion on soil productivity), producers need a working knowledge of soil properties. Iowa's soils range in thickness from a few inches to several feet. Each soil has a unique combination of properties; however, some properties are common to all soils.

The global impact of soil erosion on productivity. II

soil erosion, crop yield, crop production Abstract: Soil is one of the most important natural resources and a major factor in global food production. Soil erosion is widely considered the most serious form of soil degradation, posing a significant threat to world' food production capacity and global food security.

Soil productivity is the capacity of a soil, in its normal environ- ment, to produce a particular plant or se- quence of plants under a specified manage- ment system (96). Because of the emphasis on a soil’s capacity to produce crops, pro- ductivity should be expressed in terms of yields. Soil erosion depletes soil

The Effect of Soil Erosion on Europe’s Crop Yields

2007-9-14  Soil erosion negatively affects crop yields and may have contributed to the collapse of ancient civilizations. Whether erosion may have such an impact on modern societies as well, is subject to debate. In this paper we quantify the relationship between crop yields and soil water available to plants, the most important yield-determining factor affected by erosion, at the European scale.
