Green manuring effect of pure and mixed barley – hairy vetch winter cover crops on maize and processing tomato N nutrition

Nitrogen use efficiency and fertiliser fate in a long-term experiment with winter cover crops

“…In the barley treatment, soil available N at cover crop sowing was lower than in the vetch treatment, reducing the biomass production in the grass with respect to the legume in 2012/13 and the N content at cover crop killing date in both seasons. This is in agreement with the studies of Tosti et al (2012), who observed larger production of biomass for legume than grass cover crops under low soil N availability conditions. In the study of Gabriel and Quemada (2011) in the same plots, the soil N availability at cover crop sowing was never a limiting factor for cover crops, and therefore, the barley produced more biomass than the legume.…”

“…nutrition of high demand vegetable crops) or, conversely, they may seed pure grasses in case of low N requirement of the next crop and/or, in climatic conditions with high potential risk of NO 3 -leaching. Moreover, sowing a combination (a mixture) of different proportions (i.e 50/50 or 30/70) of legume and non-legume ASC can determine a range of intermediate scenarios, useful for "fine-tuning" N dynamic in the soil-plant system (Tosti et al, 2012).…”

Effect of Orychophragmus violaceus incorporation on nitrogen uptake in succeeding maize

“…Different kinds of cover crops and their N effects on succeeding maize production were examined (Vyn et al 1999, Astier et al 2006, Tosti et al 2012. For the complex interaction between the characteristics of cover crop, the soil, and the climate etc., cover crop could increase or decrease the N supply for a succeeding crop (Thorup-Kristensen et al 2003, and references therein), thus playing an important role in subsequent crop nitrogen uptake, yield increase and stability.…”
