Specific agricultural practices used to slow down water run-off include:
A. Contour tillage B. Strip cropping C. Terracing

Correct option is C

The correct answer is (C) All A, B and C

Explanation:
• Soil and water conservation practices are essential for reducing erosion and maintaining productivity. All three listed methods are mechanical or agronomic ways to slow down runoff.
• Contour Tillage: Plowing and planting across a slope following its elevation contour lines. This creates small ridges that act as barriers to water flowing straight down the hill.
• Strip Cropping: Growing different crops (e.g., a row crop and a cover crop) in alternating strips. The dense cover crop slows the velocity of runoff from the row crop strips.
• Terracing: Converting steep slopes into a series of broad, flat steps. This drastically reduces the slope length and gradient, allowing water to soak into the soil rather than rushing down the surface.

Information Booster:

• These practices are part of 'In-situ soil moisture conservation'.
• Reducing runoff velocity prevents the detachment and transport of topsoil particles (erosion).

Additional Knowledge:
• Mulching is another agronomic practice where crop residues are left on the surface to protect the soil from raindrop impact.
• Shelterbelts are rows of trees planted to reduce wind erosion.
