Planting Green refers to no-till planting a primary crop into an actively growing cover crop before killing it mechanically or with an herbicide. This advanced soil health practice allows cover crops to grow longer, offering improved soil health and long-term agronomic outcomes. But for many farmers, the idea of planting through shoulder-high cover crops seems risky. All that cover crop biomass might result in poor crop stands and more slugs. Fortunately, a few farmers have been planting green now for many years, and their experience and research data show that great stands and yields can be achieved with proper planning and equipment adjustments. Research also suggests that planting green may increase soil water available to the crop during the heat of summer, and even reduce slug damage instead of exacerbating it.
That’s why we (a group of University of Maryland Researchers and Extension Educators) have partnered with pioneering farmers who have long-term experience and success in planting green on their own operations across a variety of farm enterprises and soil types. The team is planning to conduct field research, on-farm trials, and demonstration days to better support Maryland farmers interested in adopting this enhanced cover-crop management practice.
We are looking to collaborate with farmers who might host replicated on-farm trials comparing several treatments, or simple side-by-side strip demonstrations (farmers would choose specific cover crops and termination strategies) – all supported by the research team and a panel of experienced farmers. Data would be collected and aggregated to evaluate soil health, agronomic, and farm management outcomes. Farmers could choose to enroll in our farmer-to-farmer mentoring program to receive additional technical assistance from researchers and farmer-mentors experienced in planting green.
It’s definitely time to plan your next cover crop moves for the coming fall and spring. If you are interested in participating (especially if you have slug problems!) or just want to learn more about cover crops and planting green, please contact one of us as soon as possible!
