Buying a farmland doesn’t make you a competent player in the agriculture business right away. Buying a farmland is actually the easiest step; sustaining what you just purchased is the harder part of the job.
You need to learn a land farm well before you consider monetizing it. How often does it rain? What kinds of pests are always on the land? What are the best crops to grow in the area? Will animals thrive in that kind of environment? Once you have the answers to these questions, only then will you know how much potential a land has.
Consider as well the people who will be running your farm. A farm is big and it is impossible to run it by yourself. Hire experienced and trained professionals to take care of your cattle and livestock, look over your crops, study the changes in the land and the like.
