Trials completed in Canterbury, Waikato and Southland have found that:
- cereals were more effective than grass species following winter grazing
- the earlier the crop is planted, the greater the opportunity to reduce nitrate leaching
- catch crops can increase total annual yield of a paddock.
Bare ground continues to be a risk for overland flow of nutrients and soil from the paddocks after grazing has finished.
- Minimise the time that the land is fallow. The establishment of new pasture or a catch crop will reduce overland flow risk.
- Consider planting a catch crop to take up some of the urinary nitrogen left from the previous winter grazing.
- Maintain the grass buffers to ensure sediment is not lost from the paddock.
