उत्तर
Top soil
Explanation:
Top soil is rich in humus which is dark brown in colour and consists of the 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 top soil. If top soil is protected or conserved then subsoil is also conserved because it lies below the top soil.
