“…In contrast to these relatively low yields at the Swedish sites, ryegrass biomass production at the Sultan site was 4.65 Mg DM ha − 1 yr − 1 . As a plausibility check, we compared these values with ryegrass cover crop yield data taken from 16 previous studies (including different ryegrass varieties) and tried to evaluate the impact of environmental variables on ryegrass yields (Askegaard and Eriksen, 2008;Caporali et al, 2004;Dapaah and Vyn, 1998;Jensen, 1992;Kramberger et al, 2009;Kruidhof et al, 2008;Kumar and Goh, 2002;Känkänen and Eriksson, 2007;Martinez and Guiraud, 1990;McLenaghen et al, 1996;Munkholm and Hansen, 2012;Reddy, 2001;Restovich et al, 2012;Sapkota et al, 2012;Thorup-Kristensen, 2001;Zhou et al, 2000). As expected, in those studies mean annual temperature (MAT) had a significant influence on ryegrass yield (Fig.…”

“…Additional variation of published FNUE rates for mineral N and slurry is due to field site history, N management, and cropping system (Xue et al 2005;Nissen and Wander 2003;Muñoz et al 2004;Stevens et al 2005;Cusick et al 2006). FNUE 15N values found for mineral N fertiliser range from 18 to 49% (Timmons and Cruse 1990;Khanif et al 1984;Zhou et al 2000;Stevens et al 2005;Vesterager et al 2008), while FNUE diff vary between 22 and 94% (Ma et al 1999;Schröder 1999;Stevens et al 2005;Nissen and Wander 2003;Halvorson et al 2005;Montemurro et al 2006). Some studies even reported FNUE diff values up to 145% (Maidl et al 1999).…”

The stable isotope technique and the difference method are common approaches for estimating fertiliser N uptake efficiency. Both methods, however, have limitations and their suitability may depend on N management and environmental conditions. A field experiment was conducted on a humus sandy soil in northern Germany to estimate fertiliser N uptake efficiency of silage maize in the year of application (Zea mays L.) by the stable isotope and the difference method as influenced by the type of N fertiliser (mineral vs. cattle slurry), the application mode (separate or combined application), and N rate. Seven N treatments were included (0, 50, 100 and 150 kg mineral N ha -1 ; 20, 40 m 3 cattle slurry ha -1 ; 50 kg mineral N ha -1 plus 40 m 3 slurry ha -1 ), where either mineral N or slurry N was labelled, and mineral N was split into two dressings. In addition, 4.1 kg ha -1 labelled mineral N was incorporated into otherwise unlabelled treatments (0, 20, 40 m 3 ha -1 , and 50 kg mineral N ha -1 plus 40 m 3 ha -1 ) to estimate N uptake from the upper soil layer. Uptake of 15 N was followed in leaves, stalk, ear, and the whole crop. Fertiliser N uptake efficiency (FNUE 15N ) of mineral fertiliser N obtained by the isotope technique ranged between 51 and 61%. Recovered fertiliser N was mainly found in the ear, while less labelled N remained in leaves and the stalk. The nitrogen rate tended to increase the amount of recovered N, but the effect was not consistent among plant parts and the whole crop. Plant N uptake from non-fertiliser N was found to increase N input up to 100 kg N ha -1 . Nitrogen recoveries of the two mineral N dressings were similar for the different plant parts as well as for the whole crop. Fertiliser N uptake efficiency (FNUE diff ) of mineral N estimated by the difference method resulted in substantially higher values compared to FNUE 15N , varying between 56 and 98%. More N was taken up from the upper soil layer with increasing N supply, which is regarded as a major error source of the difference method. Slurry N was taken up less efficient in the year of application than mineral fertiliser N as indicated by recovery rates of 21-22% (FNUE 15N ) and 39-62% (FNUE diff ), respectively. When mineral N and slurry were applied together, the difference method estimated significantly lower N uptake efficiencies for both mineral and slurry N compared to a single application, while values obtained by the isotope method were not affected.

“…Intercropping faba bean with oats or spring wheat could reduce the nitrate accumulation in soil profiles (Stuelpnagel, 1993). Intercropping maize with ryegrass is also an effective way for increasing N uptake under conditions of high N application (Zhou et al, 2000).…”
