How farmers can save their farmlands

Solution: Contour Plowing helped the farmers slow the runoff of excess rainfall and it prevents it from washing the soil away.The Conservation Plowing helped return soil nutrients,retain moisture, and hold soil in place and the farmers planted different kinds of crop rotation.Farmers can use peanut plants because they can help make soil fertility again.The peanuts plants are legumes that contain nitrogen-fixing bacteria.This bacteria makes nitrogen,an important nutrient,available in a form that plants can use.
