Keep on track to meet your Autumn grazing targets

Yara UK Stand information: A410
The requirement to build grass from August starts to become clear by mid-September. Growth rates will have started dropping below demand on most farms by late September. The objective is to keep stock out grazing longer to lower costs, with Teagasc estimating that every day at grass is worth about €2 cow/day, which should be encouragement enough to work at managing autumn grass.

Average farm covers should be hitting 2,500 kg DM/ha by late September and most farms should be out to a 35-day rotation. This means a 35 ha milking platform would be grazing 1 ha per day. If the daily grass allowance based on this rotation length is not enough to meet demand, consider reducing stocking rate or introducing supplement. A minimum 30-day rotation needs to be maintained, to grow and utilise more grass.

Nitrogen applied now is required to grow grass for the last rotation. Applying nitrogen after early October may not be economical. Apply nitrogen to paddocks that will likely give the best response. Our Calcium Ammonium Nitrate based fertiliser YaraBela Nutri Booster with sulphur and selenium at 100 kg/ha is an appropriate rate for applications from mid-September to early October. If P & K needs topping up, then a quality NPKS such as YaraMila EXTRA GRASS at 90 kg/ha should be used.

When pre-grazing yields are high, use strip-wires to ensure grazing to 4cm. Try and graze paddocks with heavier, less free draining soil types earlier in the rotation to improve graze-outs.
