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

Don’t let potash hold your 3rd cut back

If you’re planning to fertilise 3rd cuts, then we should be aiming to apply between 70 – 80 kg/ha of N. If this is not the final cut, then stay at the lower end of this range, and for those taking only 3 cuts  - then aim for the higher end of the range, as the growing period is generally longer. Spread slurry as soon as is practical after the 2nd cut harvest, and then a week later follow up with the fertiliser.

From both a yield and silage quality perspective, a sulphur (S) containing fertiliser should be used. At optimum N rates, we see a 10% increase in dry matter yields on average where S is applied, rising to 20% on very responsive lighter soil types. During dry weather, sulphur availability to the grass plant becomes even more important.

Pay particular attention to potash (K) at this stage of the year. A 23 and 15 t/ha crop of 1st and 2nd cut respectively, will remove 310 kg/ha of K2O. A 3rd cut is likely to remove another 75 kg’s, so it’s worth calculating how much K has been applied. If slurry contains 2.5 kg of K2O per cubic metre, that’s 154 cubic metres of slurry needed to replenish the K offtake from 3 cuts.

If slurry can meet the P & K demands of the 3rd cut, then an N + S fertiliser - such as YaraBela Nutri Booster could be used. If not, YaraMila NK Sulphur is an option on 3rd cuts if P is not required.
