Explain why sharecropping created a cycle of debt for farmers?

Sharecropping created a cycle of debt mainly because of the greed of the landowners. Many sharecroppers were once slaves and did not have any funds necessary for farming. So they rented the land. From their landowners they were also force to buy seeds and equipment that were overpriced with high interest rates. This kept farmers in a state of debt for many years as they on top of this signed very unfavorable contracts.
