I studied agriculture in college. Specifically, agricultural science.  I have plans to buy a farm and grow crops!
How long did you study it?
I took a 2 year course.  I learned about  agriculture, natural resources, and land management.
That is interesting, Do  you think it was worth it?
Sustainable agriculture
Sustainable agriculture is farming in sustainable ways (meeting society's food and textile needs in the present without compromising the ability of future generations to meet their own needs) based on an understanding of ecosystem services, the study of relationships between organisms and their environment. It is a long-term methodological structure that incorporates profit, environmental stewardship, fairness, health, business and familial aspects on a farm setting. It is defined by 3 integral aspects which are: economic profit, environmental stewardship and social responsibility. Sustainability
knowledge that it studies. Practical studies related to crop and livestock production and farm life gradually delved deeper as scientists strove to understand the underlying biological processes. Today the college generates new knowledge about agriculture, natural resources management and protection, human health and nutrition, community development and related topics. Faculty and staff in 19 academic departments and a number of interdisciplinary programs carry out these lines of study."
It has 12 associated research centers including the Marshfield Agricultural Research Station and research centers in Arlington among other locations in Wisconsin.
