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

Turning stock out to grass

It might seem early but on many farms across the UK, stock will be going to grass in February. It’s worth identifying what paddocks are going to be grazed first and have your reels and pigtails ready to go. Animals should start grazing on grass covers of ideally 2,200 – 2,400 kg DM/ha to ease animals back into grazing. The first animal groups to turn out to grass should be young growing cattle or freshly calved dairy cows.

As animals are turned back out to grass, allocating the correct area can be difficult. For beef animals use 2% of body weight as a good guide for intakes. A 350 kg beef animal being turned to grass, allocate 7 kg DM/Ha per day. A crossbred dairy herd after calving with 20% heifers will start off at about 13 kg DM/Ha intake so factor this in when allocating grass. If feeding 3 kg meal and 3 kg silage, then allocate 7 – 8 kg of grass DM. You can increase this allocation by 20% twice per week. Aim to have the first rotation finished by early April and no sooner.

Prioritise slurry for silage ground or on grazing paddocks which have low soil P & K indices. Try and apply more dilute slurry on grazing (~ 20 m3/ha). If applying N fertiliser, soil conditions need to be good, with minimum soil temperatures of 5 – 6 degrees. Hold off spreading if heavy rain is forecasted. We recommend 80 – 120 kg/ha of YaraBela Nutri Booster (20 – 30 kg N/ha) for this first application on paddocks that haven’t received slurry.
