Economists and educators at the University of Minnesota Extension have been researching the question of which costs have the largest impact on farm profits when it comes to crop production. A significant difference in profitability exists among farmers. A few categories of production costs, also known as inputs, vary significantly across levels of profitability, says David Bau, University of Minnesota Extension business management educator.

The farm profitability levels can be broken into five groups (bottom 20%, 20-40%, 40-60%, 60-80% and the top 20% profitability by crop).  The 2011 numbers were just made available through a farm income analysis carried out in partnership between Minnesota State Colleges and Universities (MnSCU) and the University of Minnesota.

The cost of production varies by group, starting at $5.36 per bushel of corn produced in 2011 in the bottom group, declining to $4.63 for the 20-40% group, $4.30 for the 40-60% group, $3.91 for the 60-80% group and $3.45 per bushel for the most profitable group.  There is a significant difference of $1.91 per bushel in cost of production between the top and bottom groups in profits, Bau explains.  

The most significant impact on this cost of production is the yield per acre produced, which ranged from 139 bushels per acre in bottom tier to 177 bushels per acre in the top group, a difference of 38 bushels per acre.  

One of the top five costs was seed, varying slightly among groups from $102 to $105 per acre.  Fertilizer is the second-highest cost and the bottom three tiers had similar costs at $154, $152 and $151, while the top 20% spent $118 per acre.

The highest cost was land rent, which varied, but did not vary significantly among groups.

Overall direct expenses varied significantly with the low group’s cost at $625, declining incrementally in each group with the top 20% spending $533 per acre, or $92 per acre less. Total expenses also varied significantly, with the low group at $745 and the top group at $611, a difference of $134 per acre. After accounting for direct expense variation of $92 per acre, overhead expenses varied by an additional $42 per acre. Other top expenses were repairs, fuel and oil in direct costs, and depreciation in overhead costs. Soybeans had similar results, except for fertilizer.

Bau suggests that the quality of land might be one factor resulting in better yields. Some farms may utilize manure, lowering their fertilizer costs.

Net return to labor and management income started at $63, increasing quite dramatically in each group until reaching $509 for the top 20%. The top 20% of farmers are managing much higher net returns to labor and management by $446 per acre over the bottom 20%.

Bau observes to be profitable, farmers must be the best at managing cost without hurting yields. Farmers can use the university’s Center for Farm Financial Management Web site at www.finbin.umn.edu to examine costs in any area of the state.
