March is the time of year when many farmers start thinking about over-seeding tired or worn leys with grass and/or clover. This is an excellent - and economical - way of boosting forage yields.
However, do not be tempted to add N fertiliser when over-seeding as this will promote too much growth in the existing sward and reduce the chances of the new seed coming through.
N can be added but not until new seedlings are well established in late April.
Before over-seeding check that P and K levels are around ADAS Index 2 and the pH is between 6 - 8.
