Contour farming is a technology that helps manage soil resource by A detecting if soil is losing nutrients B keeping water in the soil C preventing pollution from getting into the soil D keeping air in the soil

Answer 1

Contour farming is primarily designed to help manage water and soil resources effectively. It involves plowing and planting across the slope of the land, which helps to slow down water runoff and reduces soil erosion. Therefore, the most accurate answer to how contour farming helps manage soil resources would be:

B keeping water in the soil

This practice helps maintain moisture in the soil and improves nutrient retention, contributing to healthier crops and better soil management overall.
