Spreading 30 units/acre of nitrogen across the grazing block in late August will boost grass growth for autumn. / Donal O' Leary

Grass growth has been strong throughout August, but it will start to tail off during September.
Applying 25 to 30 units per acre of nitrogen before the end of the month will help to extend the growing season, building grass covers for autumn grazing.
The earlier fertiliser is applied, the greater the growth response. Shorter days in September will limit the growth response to any nitrogen applied.

Using products such as CAN will suffice at this time of year. Compounds also work well, but just be mindful of using a high potash (K) fertiliser on swards grazed with cows and calves, as the risk of tetany is increased.
Slurry has a relatively low nitrogen availability when applied in autumn. It will help to replace any P and K loss from grazing or silage. However, it should be topped up with chemical nitrogen to boost growth rates.
The closed period for fertiliser applications on grassland kicks in on 15 September, so ensure all swards have been dressed before then.
