This method is also known for preventing tillage erosion.

The risk of tillage erosion has, and still is, much higher than either wind or water erosion.

Limitations - Experimental data on tillage erosion is limited.

Tillage erosion Wind and water are the natural agents of erosion.

More uniform speed and depth of operation will lessen tillage erosion.

The risk of tillage erosion in Quebec remained relatively low and nearly constant over the 20-year period studied.

The tillage erosion risk indicator is subject to as yet unquantified level of uncertainty.

Consequently, changes in the area of potato crops greatly influence tillage erosion trends.

• Comprehensive experimental data on tillage erosion is lacking.

Tillage erosion is a measure of the amount of soil lost from these upper slope areas.

• tillage erosion on Canadian cropland dropped by 22%.

Models which consider tillage erosion are rare.

Tillage erosion is the soil movement and erosion by tilling a given plot of land.

Tillage erosion Displacement of soil by the action of tillage.

Tillage machinery causes tillage erosion and compaction of the soil.

As such, tillage erosion also contributes to the off-site environmental impacts of soil erosion.

Soil quality is assessed using indicators which measure the risk of soil degradation due to water, wind, and tillage erosion.

The model is simple, but very informative. The following equation is used to calculate tillage erosion rates:

The three Prairie Provinces exhibited the greatest change in tillage erosion risk and made the largest contribution to the changes observed nationally.

Implements that move less soil and move it over a shorter distance will generate less tillage erosion.

Many cropping systems, such as potatoes, will always entail some form of soil disturbance leading to soil movement and tillage erosion.

Data Sources For the calculation of tillage erosion rate (t ha-1 yr-1), information from two existing data bases were used: 1.

Assesses the change in the risk of soil degradation from tillage erosion on cultivated agricultural lands relative to changes in land management.

Tillage erosivity declined by 43% resulting in a 48% reduction in tillage erosion.

These changes, accompanied by a modest reduction in tillage intensity, spelled a 19% increase in tillage erosion.
