Wouldn’t it be great if we could take every farm and fix all conservation concerns in one year? A landowner and operator would come to the table and address fertility, drainage and erosions and then make a plan to swiftly address all three immediately. When year two rolled around, we would see increased yields for the operator and increased value for the landowner.
Many variables make this unobtainable for a farm, and because of this, it could feel like a daunting task to even start.
Some landowners have concerns of improvement projects going over budget and/or not knowing the scope of needed work, feeling inadequate in the lingo to be on shared footing with contractors and/or their operator. The farm could be on an annual cash rent lease agreement where the operator does not feel secure enough to invest in improvements that would improve the farm over time. In this scenario, there is simply no incentive to think beyond the annual, one-year lease agreement. Or maybe the landowner-operator relationship has been long term and change on either side could be a difficult step. (Add current low corn/soybean prices to tighten margins and we’ve painted quite the dreary picture!)
The good news is that if we can solve the financial issues on a farm, there is almost always a positive environmental impact. With higher commodity prices in the past, we could have a more singular focus on maximizing yield and generate significant income. But in the last couple of years, we have needed to take a hard look at where inputs are not equating to commodity. Today’s technology allows us to run modeling on an acre-scale to identify opportunities for more prescriptive management. And if we can identify the acres that are losing money, we often find those same acres have conservation issues.
The following farm is a good example of a phased approach to conservation. As we first dug into this farm, there were several items at play:
In the early stages with the landowner, we ran a soil loss report on the full 160-acre farm. The results showed that a concentrated amount of soil loss was happening on the southwest 40 acres of the farm. The results showed:
By eliminating tillage after soybeans and introducing a cover crop, we reduced our soil loss per acre by more than half as well as reduced the cumulative erosion cost by half. Having these numbers at our fingertips was a powerful tool when meeting with the operator to discuss next steps. As could be expected, these 40 acres aligned with lower yields on the annual yield maps, as well as lower organic matter/fertility levels on the recent soil test.
The landowner paid $1,360 for soil testing and agreed to a $3,000 budget to repair a few of the major waterways on the farm. Data files from the soil test were shared with the operator to allow him to variable rate apply fertilizer and lime to apply the product where it was truly needed versus a flat rate across the full farm.
In their updated farm lease, the operator was required to reduce tillage on the full farm. He had smaller equipment of his own and was able to address several of the smaller waterways that needed reshaping. All of the waterway work addressed surface water drainage for improved planting conditions in the spring. The operator agreed to try cover crops on the 40 acres identified as the poorest acres on the soil loss report and was able to secure cost share dollars to pay for half of the seed/aerial application. As he gets more comfortable with cover crops, there is discussion about expanding cover crops on the full farm in the future.
