The graph below was created using Google’s graph tool.
The line graph shows the total cost (variable and fixed) per acre, per year, to grow wheat, from 2000 to 2010. The cost data is an average cost across the United States.
The cost data was obtained from a US Department of Agriculture website. You can gain access to this data by clicking here. Costs for each expense that make up the variable (e.g. chemicals, seeds, etc.) and fixed (e.g. land, etc.) are itemized. This Department of Agriculture website has similar cost data for other commodities, e.g. corn, soybeans, etc. Also, the website presents other economic data relevant to agriculture.
The average cost to grow wheat on an acre increased approximately 5.9 % per year.
