Question

Which of the following is not a best practice for soil conservation?

Question 1 options:

Mulching—covering the soil with wood chips or other protective cover

Mechanical methods—building structures to improve drainage and decrease erosion

Crop management—changing planting patterns & planting cover crops

Bioresurfacing- increasing land and agriculture usage

Answer 1

The appropriate answer is d. Bioresurfacing by increasing land and agriculture usage. Expansion of agricultural practices means more tillage of the soil. Increasing tillage increases the risk of soil erosion and is therefore not a suitable conservation method. mulching reduces the negative impact of rain showers and helps to retain soil moisture.
Mechanical methods use man made structures to conserve the soil while crop management is a biological method of soil conservation.
