It is possible to plant grass seed with a no-till drill. In fact, it is one of the most common methods used for establishing native grass and forb mixtures. However, there are some challenges that can arise when using a no-till drill for seeding.
One of the main difficulties with using a no-till drill is achieving the correct seeding rate. This is because the bulk weight of dechaffed seed is reduced, and many common mixtures have lower seeding rates compared to traditional grass seed. The reduced weight of the seed can make it difficult to accurately measure and distribute the correct amount of seed with the drill.
To overcome this challenge, it is important to carefully calibrate the no-till drill before use. This involves adjusting the settings to ensure the correct amount of seed is being dispensed. It may also be necessary to make multiple passes with the drill to achieve the desired seeding rate.
Another consideration when using a no-till drill for grass seed is the type of seed mixture being used. Native warm-season grass (NWSG) mixtures are often recommended for their environmental benefits and suitability for specific regions. However, these mixtures can be more challenging to plant with a no-till drill due to their lower seeding rates and different seed characteristics.
In my personal experience, I have found that working with native grass seed mixtures requires extra care and attention when using a no-till drill. It is important to carefully read and follow the instructions provided by the seed supplier, as well as consult with local experts or extension services for specific guidance.
In addition to calibrating the drill and adjusting the settings, there are a few other tips that can help improve the success of planting grass seed with a no-till drill:
1. Prepare the seedbed: It is important to properly prepare the soil before using a no-till drill. This may involve removing any existing vegetation or weeds, loosening the soil, and ensuring it is well-drained.
2. Use a starter fertilizer: Applying a starter fertilizer can help promote healthy seedling growth and establishment. This can be done either before or after seeding, depending on the specific product and recommendations.
3. Monitor soil moisture: Adequate soil moisture is crucial for successful germination and establishment of grass seed. Regularly monitor soil moisture levels and irrigate as needed to keep the seedbed moist but not waterlogged.
4. Consider cover crops or mulch: Depending on the specific conditions and goals of the planting, using a cover crop or mulch can help protect the newly seeded area and promote germination. This can be especially beneficial in areas with high erosion risk or where weed competition may be a concern.
While planting grass seed with a no-till drill can present some challenges, it is a viable option for establishing native grass mixtures. With careful calibration, proper seedbed preparation, and attention to soil moisture and other factors, successful establishment can be achieved.
