Cover Crops Are a Win-Win, and Ashland SWCD is here to help
Cover crops are a win-win for farmers: they reduce erosion, build organic matter, improve water quality and even help suppress weeds. But, unlike other long-term conservation practices, planting cover crops requires an annual commitment of getting another crop into the ground. Cover crops are like a field of mini super heroes. They can battle compaction by breaking through a plow pan, improve biodiversity and attract pollinators, and they can help counteract our changing weather patterns. They can increase soil’s organic matter to help hold and retain more water during intense rain events, and a mat of cover crops in the field can also help prevent the moisture that is in the soil from being lost to evaporation during drought events. All of these benefits combined with cover crops’ filtration powers can make significant impacts on water quality.
One of the challenges that are faced when adding cover crops into rotations is another pass in the field in the fall. Farmers are faced with tighter and tighter weather windows to get their crops harvested and cover crops in the ground with our changing weather patterns. More frequent, higher intensity rain events can lay waste to the best laid plans during harvest when it comes to getting a cover crop planted. We know farmers’ first priority is harvesting their cash crop, so we hope new strategies like interseeding can open up that seeding window and relieve the time crunch our farmers feel during harvest. Interseeders are designed to allow farmers to plant cover crops earlier in the growing season—about six weeks after the initial cash crop is planted. The cover crop starts to establish, but because the cash crop has a head start, its canopy shades out the cover crop, slowing its growth. The result is that when the cover crop is harvested in the fall, the cover crop is already established and in-place in the field, so farmers don’t have to battle unpredictable fall rains to get their cover crop seeded. When the canopy opens up at harvest, the cover crop really takes off, and the soil is never without cover and protection from erosion. Extensive research has been done through universities such as Penn State and Ohio State on the benefits and challenges faced when interseeding.
Are you interested in testing out interseeding on your farm without the investment of new equipment? Recently Ashland SWCD was awarded a Partners in Watershed Management grant through that Muskingum Watershed Conservancy District that has provided funds to add an interseeder to the rental program.
