How does step farming prevent soil erosion?
The roots of the plants namely primary,secondary and tertiary roots while absorbing water from the soil, will hold the soil packets around them due to the sucking action. As the plant grows, the primary roots go deeper into the soil and the secondary and tertiary roots spread around it thus widening its base. With this the capacity of the roots to hold the soil around its periphery will increase.Thus the number of plants planted at a certain predetermined distance will help to prevent the soil erosion.
