Faba bean in cropping systems Organic Eprints
Jensen, Erik Steen; Peoples, Mark B.; Hauggaard-Nielsen, Henrik.
The grain legume/pulse faba bean (Vicia faba L.) is grown world-wide as protein source for food and feed and simultaneously faba bean offers ecosystem services such as N2 fixation and diversification of cropping systems. Even though the global average grain yield has almost doubled during the recent 50 years the area of faba beans has declined with 56% in the same period. This is especially the case for some of the former big producer countries such as China and Egypt. The yield season-to-season of faba bean and development of an industrialized agriculture based on fossil fuels (= N fertilizers, heavy mechanization) are some of the explanations for this development. Studies of faba bean in cropping systems have focussed on the effect of faba bean as a...

Legumes for mitigation of climate change and feedstock in a bio-based economy - a review Organic Eprints
Jensen, Erik S.; Peoples, Mark B.; Boddey, Robert M.; Gresshoff, Peter M.; Hauggaard-Nielsen, Henrik; Alves, Bruno J.R.; Morrison, Malcolm J..
Legumes are unique plants which contribute with several functions and services of great value for agriculture and society. Including legume food, forage and tree crops in farming systems is one approach to mitigate climate change. We have shown that the ability of the legumes to fix there own N via the symbiosis with rhizobia will reduce CO2 and N2O emissions compared to crops fertilized with industrial N. There is, however, a requirement to better understand the potential residual effects of legumes on N2O emissions. We have similarly shown that legumes have a key role in soilC sequestration and that the inclusion of legumes as sole crops, cover crops or intercrops usually enhances the rate of soil C accumulation even within relative short time periods....

Pea-barley intercrop N dynamics in farmers fields Organic Eprints
Hauggaard-Nielsen, Henrik; Peoples, Mark B.; Andersen, Mette K.; Nielsen, Anders H.; Jensen, Erik S..
Knowledge about crop performances in farmers’ fields provides a link between on-farm practice and re-search. Thereby scientists may improve their ability to understand and suggest solutions for the problems facing those who have the responsibility of making sound agricultural decisions. Nitrogen (N) availability is known to be highly heterogeneous in terrestrial plant communities (Stevenson and van Kessel, 1997), a heterogeneity that in natural systems is often associated with variation in the distri-bution of plant species. In intercropping systems the relative proportion of component crops is influenced by the distribution of growth factors such as N in both time and space (Jensen, 1996). In pea-barley intercrops, an increase in the N supply promotes...

The potential environmental benefits and risks derived from legumes in rotations Organic Eprints
Peoples, Mark B.; Hauggaard-Nielsen, Henrik; Jensen, Erik Steen.
Humans have approximately doubled the rate at which nitrogen (N) is entering the earth’s ecosystems compared to pre-industrial times (Vitousek et al. 1997, Smil 1999). The two most important sources of anthropogenic N are synthetic fertilizers and symbiotic N2 fixation by cultivated legumes (Vitousek et al. 1997). The ability of the legume-rhizobia symbiosis to improve the availability of N for other crops has been utilized for thousands of years in traditional farming systems and modern crop rotations. Before the advent of N fertilizers 25-50% of a farm was typically maintained in a legume-rich pasture or cover crop, and it has been estimated that in some farming systems in the 1950’s as much as 50% of all available N may have originated directly from...

The Use of Legumes for Agro-Energy and Non-Food Purposes Organic Eprints
Jensen, Erik Steen; Hauggaard-Nielsen, Henrik; Peoples, Mark B.; Gresshoff, Peter M.; Vance, Carroll P..
The vision of a more “bio-based economy” will mitigate global climate change by substituting fossil resources for energy and industrial raw materials by sustainable biomass resources, potentially refined to high value chemicals, materials and fuels in biorefinery concepts. Legume-based cropping systems can play a significant role for such paradigm shift, also when taking into account a potential adoption of less meat-intensive diets. The aim of this review is to evaluate the current knowledge and potential of legume use for agro-energy and other non-food purposes. Legumes contribute protein rich food and feed but also many other interesting compounds, which can be refined for pharmaceuticals, surfactants or food additives (e.g. saponins, isoflavonoids,...
