PRESENTATION OUTLINE
SOIL CONSERVATION METHODS!
CONTOUR PLOWING
In contour plowing, farmers plow their fields along the curves of a slope. This helps slow the runoff of excess rainfall and prevents it from washing the soil away.
CONSERVATION PLOWING
In conservation plowing, farmers disturb the soil and it's plant cover as little as possible. Dead weeds and stalks of the previous year's crop are left in the ground to help return soil nutrients, retain moisture, and hold soil in place.
CROP ROTATION
In crop rotation, a farmer plants different crops in a field each year. This enables farmers to increase soil organic matter content, soil structure, and rooting depth.
BUFFER STRIPS
Buffer strips are vegetive active areas that separate field boundaries from watercourses. These areas allow soil particles to settle out of the runoff water and they prevent soil and contaminants from entering watercourses by providing an area for field runoff to collect.
