Spreading nitrogen and sulphur at the same time means more grass
Applying fertilisers containing nitrogen and sulphur means the grass uses nitrogen more effectively, you get more kgs of dry matter per kg of nitrogen that you apply

Extending the grazing period
If grass growth rates are running ahead of demand, then now is the time to focus on building grass covers on the grazing platform to increase the number of days at grass and animal performance. Teagasc estimate that on dairy farms, every extra day a cow spends out grazing is worth over €2/cow/day.
Because grass remains leafy now, rotation length can be extended from the 2nd week in August. The focus of this period is to gradually build pre-grazing covers, targeting covers of 3,500kg to 3,700kg DM/ha in mid-September. Be careful not allow covers build beyond 4,000kg DM/ha for grazing, as utilisation is poorer. We want to avoid taking paddocks out for silage after the start of September, as these paddocks won’t have enough time to re-grow to make a significant contribution to the last rotation.
Nitrogen should be spread in August and September to provide grass for later in the Autumn. The growth response to October applications is likely to be significantly lower and may not be economical. Our CAN based fertiliser YaraBela Nutri Booster with sulphur at 120 kg/ha is an appropriate rate for applications during August and into the first half of Septem-ber. If P & K needs topping up, then a quality NPKS such as YaraMila EXTRA GRASS at 110 kg/ha should be used.
Drier or ‘earlier’ paddocks should be grazed from mid-September and then closed off from October onwards. Regrowth on these parts can be carried over the winter months for grazing first in the spring.
