The response of celeriac yield, quality and soil nitrate residue to nitrogen fertilization and supply Instituut voor Landbouw-, Visserij- en Voedingsonderzoek
Despite major efforts to reduce nitrogen (N) losses, nitrate (NO3-) concentrations in surface and groundwater remain too high, especially in field grown vegetable production regions. Stringent N fertilization rates stay the best strategy to increase N efficiency. We collected data from 4 Flemish celeriac fields where crop and soil measurements were done during the cropping period. We also re-analyzed 9 celeriac field experiments with various N ...
