Moreover, NT soil under legume cover crops behaved as a net sink for GHG (GWP ranged from 971 to 2818kg CO2 eq ha1 year1) [8]. In addition to serving as fundamental, worldwide source of high-quality food and feed, legumes contribute to reduce the emission of greenhouse gases, as they release 57 times less GHG per unit area compared with other crops; allow the sequestration of carbon in soils with values estimated from 7.21gkg1 DM, 23.6 versus 21.8gCkg1 year; and induce a saving of fossil energy inputs in the system thanks to N fertilizer reduction, corresponding to 277kgha1 of CO2 per year.

Reckling M, Schlfke N, Hecker J-M, Bachinger J, Zander P, Bergkvist G, et al. Most cultivars of birdsfoot trefoil grow to a height of two to three feet and produce stems that are not quite as big around as alfalfa. The nitrogen effect component is a result of the N provision from BNF [77], which is highest in situations of low N fertilization to subsequent crop cycles [82]. Most legumes also develop tap roots that allow them to obtain moisture from deep within the soil. Conversely, yield benefits are lower in Mediterranean climates where water availability is the limiting factor to cereal yields [46, 61, 62].

Article The low diffusion of legumes cultivation is also due to reduced and unstable yields and susceptibility to biotic and abiotic stress conditions; the average yields for unit area have increased (soybean +86%, lentil +77%, groundnut +75%, chickpea +70%) less than cereal crops (+104%, on average) (Table1). 0000004721 00000 n Rotation strictly defined, refers to a recurring sequence of crops, forages and fallows, or more loosely defined, to a cropping sequence that contains fallows, or crops and forages in addition to the locally dominant species.

The impact of humans on the nitrogen cycle, with focus on temperate agriculture. Indeed, legumes are pivotal in many intercropping systems, and of the top 10 most frequently used intercrop species listed by Hauggaard-Nielsen and Jensen [32], seven are legumes One of the basic spatial arrangements used in intercropping is strip intercropping, in which two or more crops grow together in strips wide enough to permit separate crop production using inputs but close enough for the crops to interact. However, the P uptake and the changes in rhizosphere soil P pools seem to depend also on legume species. Clover can cause bloating when the clover/grass ratio is too high. 2013;112:20722. In Denmark, nitrogen uptake in crops that follow legume crops has been reported to increase by 2359% after field pea and narrow-leafed lupin on different soil types [40], but only 1415% for durum wheat following vetch in a semi-arid Mediterranean environment [28].
