According to the research, the correct option is contour farming. It is the agricultural technique which involves turning the soil over and parallel to the hill in order to prevent soil erosion.
<h3>What is contour farming?</h3>
This is a soil conservation practice and to reduce erosion, it consists of arranging crop rows across the slope, following the contour lines.
Specifically, this practice helps to reduce water runoff and soil drag, since when planting the rows of crops against the slope, the other tasks of the crop, such as cleaning and hilling, are done in the same way and each furrow or row of the crop oppose the passage of rainwater that fails to filter into the soil, slowing down its speed, and thus there is less soil and nutrient runoff.
Therefore, we can conclude that according to the research, the correct option is contour farming. It is the agricultural technique which involves turning the soil over and parallel to the hill in order to prevent soil erosion.
