Take every opportunity to get cows to grass. Good-quality grass will save up to €2.75/cow/day and cows will be healthier, with higher milk protein and lower SCCs. Cows will consume almost their full requirements in three hours of grazing after each milking. Leave about one week between applying nitrogen fertiliser and slurry.
Apply half a bag of urea per acre for both first and second grazing. Urea is the cheapest source of nitrogen, but do not apply it on soils that have been limed since last autumn. Less than half of our tested soils had adequate lime, P and K for optimum grass growth. If you don’t know the nutrient status of different parts of your farm, test them now, before you apply P, K or lime.
This will save money and increase farm output. There is a poor return from applying nitrogen to pasture with low levels of ryegrass or low in P, K or lime. If in doubt about soil fertility, use a high-N compound rather than straight-N. risk of ketosis, milk fever and other diseases.
