The Clover Reporter with Peter Doyle, Derrypatrick Herd Grange
Peter Doyle, Derrypatrick Herd Grange is this week's Clover Reporter. We get an update on the management of the existing grass- clover swards for the summer, of 2022 oversown paddocks and of the 2022 reseeded paddocks on the Derrypatrick farm.

Management of existing grass- clover swards for the summer
Continue to graze covers of 1400 kg DM/ha down to 4 cm. Soil fertility will be corrected where necessary to optimise clover persistence.
Management of 2022 oversown paddocks
We are very happy with the oversown paddocks to date this year. However, the current soil moisture deficit is causing significant stress on this year’s oversown clover, so we are hoping for a good spell of rain to prevent any further damage. The newly established clover roots are strongly anchored into the ground at this stage so we are grazing the paddocks good and tight to maximise light exposure. On average we have applied 15 kg N/ha on ground since it was oversown. Currently we are fortunate to have a good grass supply on the farm so we are applying no chemical N on the oversown clover for July.
Management of 2022 reseeded paddocks
Clovermax was successfully applied to swards 5 weeks post reseeding and when rain was forecasted (to avoid spraying during heat stress). However, clovermax does not kill chickweed and if not controlled chickweed can smother out establishing clover. Therefore, we are currently grazing the reseeds to 4 cm and below to remove the chickweed from the sward. Fields reseeded in mid-May have been grazed twice to-date (see picture above).
The Management and establishment of grass-white clover swards booklet discusses and sets out the principles for the management and establishment of grass-white clover swards so that the benefits can be achieved at farm level.
