| I markforsøg blev det undersøgt hvorvidt samtidig såning af ærter og vinterkorn kunne øge kerneudbytter i kornet. Princippet i dyrkningsmetoden er at ærterne i løbet af efteråret via biologisk N-binding optager luftens kvælstof, som efter ærternes udvintring friggives til kornafgrøden i det tidlige forår. Sammenfattende kunne det konkluderes, at såfremt der ikke er større udgifter forbundet med anskaffelse af ærteudsæd (evt. ærter af egen avl), kan dyrkningssystemet med fordel anvendes. Specielt i år hvor de klimatiske forhold gør det vanskeligt at udbringe gødning tidligt, vil ”ærte-kvælstof” kunne sikre at kornafgrøden kommer godt i gang. |

| Wheat (Triticum aestivum L.) cultivars may have differential effects on soil microbial communities and the breadmaking quality of harvested grain. We compared six Canadian spring wheat cultivars under organic and conventional management systems for yield, breadmaking quality and soil phospholipid fatty acid analysis (PLFA) profile. Yields were lower, but protein levels were higher in the organic system. Cultivars differed for quality traits, but all cultivars had acceptable levels for processing. There were small differences in PLFA profiles for cultivars in the conventional system, but none in the organic system. More significant correlations between grain quality and PLFA measures were present in the organic system. Protein levels and breadmaking quality... |

| Abstract - Six cropping systems, ranging from conventional arable without livestock to organic livestock farming dominated by ley, have been compared since 1990 in SE Norway. Earthworm density (ED), earthworm biomass (EB), channel density (CD) and species of worms were measured in the topsoil (0-25 cm) in 1994 and 2004. Ley in the crop rotation increased EB, ED and CD in both organic and conventional systems, but a ley proportion higher than 25 % only increased CD. Among the arable systems, the organic system hosted more individuals (ED) and a higher biomass (EB) of earthworms as compared to the conventional systems. The conventional arable systems had low values in 2004, and only minor changes in EB and ED during the period compared with the other... |
