The benefits of intertillage include all except a greater yield.
In the case of one crop being unable to produce as much as expected, intercropping is a great insurance policy for farmers. In this way, they can grow a secondary crop that can supplement their primary crop or even provide a cash crop.
This type of cropping also helps in averting soil runoff and controls the growth of weeds. It also conserves the fertility of the soil and prevents its erosion by the wind. It also strengthens the roots of the crops and provides crop shade. It reduces production costs and uses water efficiently.
