As spring approaches, tackling grassland weeds early, at establishment of a new grass ley, will help improve sward palatability, productivity and reduce costs.
High levels of weeds in grass swards not only reduce pasture’s nutritional value, but restrict grazing areas, says Mark Ballingall from SRUC. Most weeds reduce the nutrition of the sward and provide excessive competition for valuable grasses, particularly in newly sown leys.
Nettles, thistles and ragwort discourage grazing and can make hay and silage unpalatable. A number of weeds are listed in the Injurious Weeds Act: common ragwort, spear thistle, creeping or field thistle, broad-leaved and curled dock. These weeds require management to prevent their spread. Poisonous weeds must also be a priority.
