How can doing less earn you more?
Mark Licht discussed how you can do just that by making the transition to no-till soybean and adding a cover crop ahead of soybeans during our Iowa Learning Farms webinar yesterday.
Compared to conventional systems with a fall and spring tillage pass, no-till can lower input costs by about $30, while also saving the time not running the equipment. By lowering input costs overall profit per acre can be increased by nearly 17%, according to a 10 year research study at seven ISU research farms.
No-till can also significantly reduce soil erosion and phosphorus loss, compared to chisel plowing. That same 10 year study, showed a 90% reduction in phosphorus loss.
Cover crops also help reduce soil erosion and phosphorus loss, while also reducing nitrogen losses from the landscape. Mark noted that cover crops are an easy entry point for farmers and landowners to voluntarily help meet the Iowa Nutrient Reduction Strategy goals. If 75% of Iowa soybean acres were seeded to a cover crops, we would reach 60% of our nutrient reduction goal!
According to a nine year study by the Iowa Learning Farms and Practical Farmers of Iowa, the long-term use of winter cereal rye shows no yield impact on soybeans in most years. In fact, for eight sites there was an average 8 bu/ac increase following cereal rye.
