Grain legumes in crop rotations cause significant increases in yield for succeeding non-
legumes, which cannot be explained simply by the small effect that legumes have on the soil …

Correct assessment of the rhizodeposition of N in grassland is essential for the evaluation of
biological N2-fixation of legumes, for the total N balance of agro-ecosystems, and for the pre …

The residual N contribution from faba bean (Vicia faba L.), pea (Pisum sativum L.) and white
lupin (Lupinus albus L.) to microbial biomass and subsequent wheat (Triticum aestivum L.) …

Nitrogen (N) transfer from one species to another is important for the N cycling in low-input
grassland. In the present work, estimates obtained by an indirect 15 N dilution technique …

The interactions occurring between biochemical composition and N content of crop residues
while decomposing in soil, and the associated N dynamics were assessed by studying the …

In situ 15 N-labelling was used to provide a quantitative assessment of the total contribution
of lupin (Lupinus angustifolius) to below-ground (BG) N accumulation during a growing …
