Solution

The correct option is B Soil is protected against loss

Soil conservation is a method of protecting soil from getting eroded either by wind or by water.

  • Few soil conservation methods include:
  • Graduated terrace steps which are commonly used to farm on hilly or mountainous terrain. Terraced fields decrease both erosion and surface runoff.
  • Wind breaks: Row of trees or a fence, wall, or screen that provides shelter or protection of soil from the wind.
  • Conservation tillage is a method of preparing soil from getting eroded. This technique involves leaving the previous year crop residues until the next crop is planted.
