Understand the concept of contour farming: Contour farming involves plowing along the natural contours of the land, especially on slopes, to create ridges and furrows that follow the land's elevation. This practice is primarily used in ecological management to address soil and water conservation issues.
Analyze the options provided: The question asks for the primary purpose of contour farming. Carefully evaluate each option to determine which aligns with the ecological benefits of this practice.
Option 1: 'To reduce soil erosion by plowing along the contours of hills' - This aligns with the purpose of contour farming, as the ridges created by plowing along contours slow down water runoff, reducing soil erosion.
Option 2: 'To increase the speed of water runoff on steep slopes' - This is incorrect because contour farming is designed to slow water runoff, not increase it, to prevent soil erosion.
Option 3: 'To maximize the use of chemical fertilizers on farmland' and Option 4: 'To promote monoculture by planting a single crop species' - These are unrelated to the primary purpose of contour farming, which focuses on soil and water conservation rather than chemical or crop management.
