How to establish a new grass ley

TO establish a new grass ley, lime the field if necessary, so that seed is sown into soil with a pH as close to 6.5 as possible.

Try to maintain a stable pH in the future.

Check the drainage status as undesirable weed grasses will invade waterlogged fields. Consider sward lifters, mole ploughs and other means of relieving compaction if you discover that this is a problem. Digging a few deep holes in the field to check soil structure is a worthwhile investment of your time and effort. Analyse the soil and correct any obvious nutrient imbalances. Prepare a fine, firm and weed free seedbed.

Timing of the sowing is important. Spring sowing from March to mid-May and from July until late September – depending on where you are located and the altitude.

Mixtures with clovers are best sown when soil temperatures are higher, from April through May and July and August. Clovers require soil temperatures of at least 5-10oC to germinate and higher temperatures to achieve satisfactory growth.

Ensure the seedbed is sufficiently moist and if possible, avoid midsummer seeding in drought-prone years.

Ring roll prior to seeding to close any gaps and again after sowing to ensure close contact between the seed and the soil.

Broadcast or cross drill and then roll or very lightly harrow. Ensure that the seed is placed no deeper than 6mm.

If you use a cover crop, make sure that it is suitable to establish a grass ley and that the seed rate is not too heavy as the grass may get crowded out.

Watch for any signs of pest attack and consult your agronomist if you see anything. (See separate section on Integrated Pest Management IPM).

Specify a Sinclair McGill mixture treated with HEADSTART® GOLD to improve establishment, increase plant stand and get your new ley off to a vigorous start.
