Perfect penetration in hard soils. of the tines ensure plant residues remain on the surface thus keeping soil erosion to a minimum.
Land use/cover and soil erosion Soil erosion affects soil health and productivity by removing the highly fertile topsoil and exposing the remaining soil. It decreases agricultural productivity, degrades ecosystem functions and Sheet erosion is the second stage of the erosion where a thin layer of the soil is removed. This can occur when heavy rain occurs, or the shallow surface begins to runoff from water flow. This results in the loss of the organic matter and nutrients since the top layer of the finest soil particles are lost.
The top layer of soil is very light which is easily carried away by wind and water. The removal of topsoil by the natural forces is known as soil erosion. Causes of Soil Erosion Various agents, like wind, water, deforestation, overgrazing by cattle, etc., cause soil erosion.

A Handbook of Pollinator Diversity and Conservation in East Africa. Dino J Martins include water resources, fertility of soil, energy from biomass, control of soil erosion, and pollination.
8 Mar 2016 Every year, erosion causes loss of tons of topsoil which is high in nutrients and organic matter that can lead to reduced yield potential. Topsoil

Erosion is the removal or wearing away of topsoil. It often Soil erosion is a concern not only for its impacts on plant growth, but also for its impacts to water quality. Soil is a valuable natural resource that nourishes and Soil Properties Erosion removes a field's original topsoil, causing the subsoil to mix with the remaining topsoil during annual plowing. In mature soils (like many 26 Nov 2010 About one millimetre of top soil is being lost each year with a total loss of 5,334 million tonnes annually due to soil erosion, Minister of State for Soil erosion is the absolute loss of topsoil and nutrients carried away from the land by water or wind and transported to other surfaces.

Climate, vegetation cover, land use, topography and soil characteristics as well as conservation practice have a strong impact on soil erosion rates. Soil erosion reduces the ecological functions of soil over time. How to Prevent Seed and Soil Erosion on Slopes and Hills One of the most efficient and cost-effective ways to control erosion is with healthy, dense grasses. Planting grass seed on slopes and hills isn't difficult when you have the right seed for the job and know how to hold grass in place where it's planted.

This can occur when heavy rain occurs, or the shallow surface begins to runoff from water flow. This results in the loss of the organic matter and nutrients since the top layer of the finest soil particles are lost. At best, erosion is unsightly. Rainfall or excess irrigation causes runoff from our lawns, roads, parking lots and farm fields.
