For pasture damage during winter, research carried out in Taranaki during the 1980s found that oversowing and undersowing ryegrass seed into damaged pastures increased dry matter production by 1-2t/ha in year one and year two following sowing.
A DairyNZ led industry group comprising researchers, seed industry and contractors have agreed on an approach for farmers faced with this situation. This group recommends farmers carry out a paddock by paddock assessment of the damage by ranking paddocks one to five based on the extent of damage. They should then use the tools suggested actions to establish a plan for each paddock.
