Grassy corners and blocks are one of the simplest Sustainable Farming Incentive (SFI) options to implement, but to maximize benefits for the farm and the environment, it is important to go beyond the minimum requirements.
CAHL3 or AHL3 (depending on the year) pays £590/ha and must remain in place for the duration of the agreement. In 2024 agreements, they are part of the limited area actions and should not exceed 25% of the farm area.
Creating a grassy field corner or block with an intact grass sward throughout the year is the goal, providing habitat for wildlife and supporting integrated pest management. Choosing to sow specific species rather than relying on natural regeneration can lead to greater environmental and agricultural benefits.
Selecting deep-rooting species that form tussocky structures, such as cocksfoot, tall fescue, and meadow fescue, is key. A recommended mix includes 30% cocksfoot, 25% meadow fescue, 18% red fescue, 15% tall fescue, 10% timothy, and 2% tufted hair-grass.
Location plays a crucial role in maximizing benefits, with optimal spots including awkward corners, areas around telegraph poles, and odd shaped field boundaries. Spreading AHL3 refuge areas around the farm and incorporating them with other options like pollen and nectar flower mixes can enhance the overall impact.
Establishment involves sowing a fine, firm seed-bed, with seed rates of about 20kg/ha broadcast in either April or August. In the first year, mowing as needed is recommended, avoiding cutting the grass at the end of the season to preserve the tussock structure.
In year two, reducing cutting is advised unless necessary to address specific issues. Utilizing grassy strips to build beneficial insect populations can help in managing crop pests, but it is not a complete solution. Connecting strips to headlands or leaving a small percentage of grass structure in in-field strips can enhance effectiveness.
Overall, implementing grassy corners and blocks not only benefits wildlife and the environment but also contributes to more sustainable farming practices.
