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...

Kalium til økologiske afgrøder Organic Eprints
Tersbøl, Michael.
Korn kan selv ved lave kaliumtal dyrkes uden udbyttetab, mens bælgplanterne markært og hestebønne, er mere følsomme overfor kaliummangel. På grovsandet jord er der ingen grund til at opretholde et højt kaliumtal, da det giver større tab ved udvaskning. Men visse afgrøder som ært, hestebønne og kartofler kræver tilførsel af kalium om foråret, hvis kaliumtallet er lavt. Disse resultater kommer fra forskning på FØJO's værkstedsarealer.

Up-scaling organic by default agriculture- a hope spot for drylands Organic Eprints
Sharma, Arun K.
A workable model of upscaling of organic agriculture in drylands has been developed. The traditional default organic system have been improved with modern ecotechnologies. Outcome in term of soil and biodiversity improvement, resilience in crops to climate change are visible that convince farmers for adoption. Continuous customised advice further enhances adoption. This approach can be the way to conserve time tested and ecofriendly heritage agriculture that is otherwise vanishihg due to intensive chemical agriculture.
