Slurry spreading is normally restricted to grassland designated for cutting because of a risk of rejection of contaminated herbage by grazing cattle. Spreading on both cut and grazed areas would allow greater flexibility in time and rate of application and reduce the risk of water pollution. Shallow injection, a technique in which slurry is pumped into slots cut into the sward to a depth of ca. 60mm, reduces herbage contamination so may allow earlier subsequent use for grazing without detriment to animal intake.
