Disc the field in several directions to open up slits in the ground. Afterwards the ground should be rolled before rain to achieve good seed to soil contact, conserve moisture and ensure rapid germination. The technique has worked well for introducing clover into an existing sward. It would not be recommended for the introduction of grass seed. Hatzenbichler Vertikator - this uses a bank of 100 spring tines to tear the existing grass and loosen surface soil.
Seed is distributed between the tines and incorporated into the disturbed surface.
Early season - Set stocking with the use of buffer grazing to control grass. Late season - Avoid poaching. Use slurry and limited early nitrogen to boost grass growth in spring. Minimal cultivation techniques increase clover at low cost. Rest swards mid-season.
