Field-scale spatial variation in yields and nitrogen fixation of clover-grass leys and in soil nutrients	2008	18	.pdf	application/pdf	10507	508	70	In those cuts with low Ndfa, a negative correlation was found between Ndfa and Ntot content of grasses, which is in line with the findings of Hansen and Vinther (2001) and might indicate higher soil N. The higher amounts of BNF have been ex- plained in many cases by higher clover dry matter production, not by higher Ndfa (Väisänen et al. 2000, Huss-Danell et al. 2007).
