Question
Soil conservation measures are mainly aimed at protecting one of the following?
Options
Plants
Topsoil
Subsoil
Soil organisms
Solution
Topsoil
Explanation:
Topsoil is rich in humus which is dark brown in colour and consists of decaying remains of plants and animals. Humus improves the texture of the soil and provides nutrients for plant growth. So, it is the most fertile region and soil conservation measures are mainly aimed at protecting topsoil. If topsoil is protected or conserved then subsoil is also conserved because it lies below the topsoil.
