Maize is one of the most important crops, especially on dairy farms. Because dairy farms are so nutrient-rich, they are often associated with nitrate leaching. To avoid N leaching during the winter period, the implementation of catch crops is important. In the new DiverIMPACTS factsheet, practical recommendation show how combination of catch crops and organic root fertilization stabilizes yields, reduces costs for mineral fertilizers and reduces necessary storage for slurry or manure.
