Severe fires can lead to significant further erosion if followed by heavy rainfall.
It also reduces the speed of water flowing over the land. Soil Erodibility Soil erodibility is an estimate of the ability of soils to resist erosion, based on the physical characteristics of each soil.
Other methods of investigating the effects of erosion on crop productivity include greenhouse studies, intentional erosion plots in which erosion is promoted for study purposesstatistical methods such as factor analysis, and simulation models Olson et al.
Texture is the principal characteristic affecting erodibility, but structure, organic matter and permeability also contribute. Effect of past soil erosion on crop productivity in Indiana.
Vegetation and residue combinations that completely cover the soil and intercept all falling raindrops at and close to the surface are the most efficient in controlling soil erosion e.
Because of the potential seriousness of some of the off-site impacts, the control of "non-point" pollution from agricultural land is an important consideration. Surface soil degradation and soil productivity restoration and maintenance. It can be caused by natural hazards, mismanagement of land as well as unsuitable land use.
Soil erosion impact on agronomic productivity and environment quality. Soil degradation is a growing problem throughout the world, and an important topic for our times as it affects the food we eat every day. Natural erosional processes occur most intensively in mountainous regions Figure 2 and generate approximately 20 gigatons of sediment annually Wilkinson and McElroy
