Gandy Cover Crop Seeders

Welcome to the Gandy Company Cover Crop Page. Our goal is to provide you with important information regarding the benefits of planting cover crops with Gandy’s OrbitAir® Seeder.





  1. Why plant Cover Crops? Cover crops have been around for a long time. While there are many reasons to plant them, some of the most popular reasons are to prevent erosion, improve soil organic matter, improve soil aeration, improve cash crop yield over time andprovidenutrients to the soil.
  2. What types of seed do you plant? The types of cover crop seeds varies dramatically by both region of the country and when you are planting. We strongly suggest you consult your local soil and water team or you university extension office for suggestions on what type of seeds work best in your area. Some farmers will plant one type of seed while others use “cocktail” mixtures of seeds. Some examples of cover crop seeds include: annual rye grass, cereal rye, crimson clover, winter peas, hairy vetch, turnips and radishes just to name a few.
  3. When do you plant cover crops? Again, the answer varies by region. Some of the most popular times to plant cover crops are after harvest using seeders mounted on some type of tillage equipment or harvesting equipment, interseeding cover crops into standing crops from June to August and at the time of planting cash crops. A lot depends on the type of seed and the equipment you are using.
  4. How do you terminate your cover crop prior to the next planting season? There are various ways depending on the seed variety you have planted. Some seeds will “winter kill”. Others will come back in the spring and can either be terminated by spraying, crimp rolling or spring tillage. Many farmers also choose to plant into the cover crop.
  5. What is the effect of herbicides on cover crops? Read the label on your herbicide to determine the residual holdover for the type of seeds you are planning to plant. You can access additional information from the suppliers of your herbicide and seed or your local university extension office.
