Answer:
Plantations and/or sharecropping land.
Explanation:
In the south ( I assume you are referring to the American Southern States) there were many plantations to produce as much crop as possible. They used slaves to take care of and 'own' a patch of the owners land, (sharecropping) with the former taking up to 75% of the produced crop. the most common plantation consisted of a big farmhouse, and some small living spaces for slaves. The rest was all crop field, where the slaves where sent to work day in and day out. Sharecropping and Plantations was mostly found along the African American population, but it was not uncommon to see a poor Caucasian American sharecropping. (the latter would most likely receive better benefits due to being white). Plantations started in the 17th Century and went onto the late 1930s upon the New Deal contracts and the commission of Tractors and machines.
