Final answer:
Planting along the natural slope to reduce erosion is called contour farming, which enhances water infiltration and soil protection.
Step-by-step explanation:
The definition of planting along the natural slope of the land to reduce soil erosion is called contour farming. Contour farming involves planting crops in concentric circles or contour lines around a hill, which conforms to its natural shape and gradient. This agricultural practice capitalizes on the benefits of minimal or no tillage methods to protect soil organisms, promote water infiltration, and prevent topsoil erosion.
The adoption of such practices has become increasingly important for ecologically sustainable farming—an approach that aims to maintain the long-term productivity of food-producing ecosystems—while also aiding in soil fertility, diversified cropping, and reduced use of pesticides.
