YR, PdSB, MC, GAvK and BV contributed to the conception of the study and the writing of the manuscript.
YR- was involved in designing and coordinating the study, collected the qualitative data, conducted the first analysis of qualitative data, drafted the initial report and contributed to the drafting of the manuscript.
In addition, nitrogen and phosphorous loads to Køge Bay are estimated to be reduced by approx. 63 t yr.− 1 and 9 t yr.− 1, respectively, contributing to the achievement of more than 70% of the nutrient reduction target set for Køge Bay in the first WFD river basin management plan.
However, the LOD peaks for the FH and FP QTL over the 2 yr are sufficiently far apart to suggest that there may be multiple linked loci contributing to the effects for each trait.
