FAQ - Pasture mixtures

We have listed the frequently asked questions on pasture mixtures for you and provided concise answers.

Until when can I seed in the autumn?

The timing for seeding in the autumn depends on the grass species included in the seed mixture. Italian ryegrass can be seeded until mid-November, thanks to its hardiness. However, clover must be well-established before winter, requiring seeding by mid-September to ensure adequate development. Ultimately, the winter hardiness of the grasses dictates the ideal seeding time. Refer to the product information of the specific mixture for detailed seeding schedules.

What is the ideal stubble height?

For optimal regrowth after mowing, maintain a stubble height of 5 to 6 cm. Cutting too heavily leaves behind yellowing undergrowth, which hampers regrowth and increases the likelihood of weed establishment. Conversely, mowing too low also slows regrowth. Ensuring the right stubble height and cut weight is crucial for maintaining healthy grass.

How much should I seed?

The seeding rate depends on the mixture and field conditions. For well-prepared fields, use the lower end of the recommended rate. If seeding later in the year or under less favorable conditions, apply the upper limit of the recommended rate. Always check the product information for specific seeding rates.

When can I seed in the spring?

Spring seeding is feasible when the field conditions are right—neither too wet nor too dry, and free from weeds. Early spring seeding is preferable as it allows for an earlier first cut. Ensure the field is suitable for machinery to operate without compacting the soil.

Why should I seed timothy?

Timothy grass is highly winter-hardy when seeded well before winter and has rapid spring growth, leading to early yields. It is resistant to crown rust, maintaining palatability throughout the autumn. Timothy is consistently flavorful year-round, making it a valuable addition to grass mixtures.

What are the advantages of clover in a grassland mixture?

Clover, a legume, fixes nitrogen from the air into the soil, reducing the need for nitrogen fertilization. This is beneficial for compliance with nitrogen regulations like Minas. Clover maintains grassland productivity and palatability by continuously releasing nitrogen, preventing rust, and promoting higher milk yields in cows compared to grass-only diets. Including clover helps meet regulatory standards while providing a tasty pasture year-round.

What is the importance of sward persistence?

Grass varieties scoring between 7.5 and 8.5 on persistence are recommended. While differences may seem minor on paper, they significantly impact field performance, especially in spring. Low persistence results in an open sward and higher weed pressure. With decreasing nitrogen application, grass must grow more independently, increasing weed competition. As fewer herbicides are available, selecting persistent varieties becomes crucial. A persistent sward, combined with robust soil, effectively suppresses weeds.

What is the difference between reseeding and overseeding?

Overseeding is commonly performed in spring on fields with uncertain yields. It introduces new, more productive grass into the sward without the costs of complete reseeding (spraying, tilling, plowing, and leveling). Due to competition from existing grass, use mixtures with Italian or perennial ryegrass for overseeding. Effective mixtures include BG 3 Superplus and Overseeding Mix.

What is the difference between tetraploid and diploid grasses?

Grass plants typically have diploid cells (two sets of chromosomes). Tetraploid grasses, developed through breeding, have four sets of chromosomes. Tetraploids generally yield higher, have more open swards, and are less susceptible to crown rust, making them more palatable. Diploid grasses form denser swards, have a higher dry matter content, and are more persistent. Grass seed mixtures often combine both types to leverage their respective advantages.
