| Moyer gjestet nylig Norge, med foredrag om økologisk landbruk med lite jordarbeiding og hovedfokus på vekstskifte og dekkvekster, kalt «organic no-till farming». Ved det økologiske senteret Rodale i Pennsylvania har de drevet feltforsøk og utprøvinger i over 30 år. De mener det er viktig at jorda er plantedekket hele tiden, dette for å hindre erosjon, holde på næringsstoffene og for å holde jordlivet aktivt og bedre jordstrukturen. Jeff Moyer sammenliknet jordlivet med en gjeng idrettsutøvere. For å kunne omdanne mye organisk materiale nytter det ikke å ligge på sofaen mesteparten av året, for så å skulle prestere maksimalt i en kort periode om våren. Derfor er plantedekke og jevnlig tilgang på organisk materiale (røtter og roteksudater) viktig for å... |

| Utilizing animal slurry to produce biogas may reduce fossil fuel usage and emissions of greenhouse gases. However, there is limited information on how the recycling of digested slurry as a fertilizer impacts soil fertility in the long run. This is of concern because organic matter in the slurry is converted to methane, which escapes the on-farm carbon cycle. In 2010, a study of this question was initiated on the organic research farm in Tingvoll, Norway. So far, a biogas plant has been built, producing anaerobically digested slurry to be compared with undigested slurry in perennial ley and arable crops. Effects on crop yields, soil fauna, microbial communities, soil structure, organic matter and nutrient concentrations are measured. |

| Little is known about Collembola in arable soil, at least in Norway. Recently, a study including this group has been initiated in a Norwegian field experiment Soileffects). Collembola (springtails) are a group of small animals (1-3 mm) living in vegetation,litter and in the pores and caves in the soil to a depth of ca 15 cm. They are important decomposers of dead plant material, eating fungi, algae and microorganisms in soil and on organic debris. Their grazing and decomposing activity contribute significantly to the nutrient circulation in the soil. The name springtail refers to a furca on their back, usually folded in under the body, but released in need of a rapid escape. In one jump, Collembola can jump more than 50 times their own body length. In... |

| The diversity and density of springtails (Collembola) were studied in an organically managed grass-clover ley at Tingvoll experimental farm in NW Norway during 2011–2012. In total after one sampling in 2011 and 3 samplings in 2012, 42 species were identified. Our results included a new species for the Norwegian fauna, Onychiurus edinensis (Bagnall, 1935) and one species very unusual to agricultural soils, Oligaphorura ursi (Fjellberg, 1984). The most abundant species was Parisotoma notabilis (Schäffer, 1896), followed by three species of Mesaphorura Börner, 1901, two species of Protaphorura Absolon, 1901 and Isotomurus graminis Fjellberg, 2007. A high number of P. notabilis has also been found in pastures in Iceland (Gudleifsson & Bjarnadottir 2008),... |

| In repeatedly mown and mulched green manure leys, the mulched herbage contains substantial amounts of nitrogen (N), which may only slightly contribute to the following crops’ nutrient demand. The objective of the present work was to evaluate the effect of alternative strategies for green manure management on the yield and N recovery of a subsequent spring barley crop, and their short term effects on soil structure and earthworm populations. A field trial was run from 2008 to 2011 at four sites with contrasting soils under cold climate conditions. We compared several options for on-site herbage management and the application of anaerobically digested green manure herbage. Depending on the site, removal of green manure herbage reduced the barley grain yield... |

| In controlled indoor experiments, and a field experiment at Tingvoll farm in 2016, we studied the effect of mixing finely ground calcium carbonate made from marble into animal manure slurries, and digestates. In field, 6% higher yields of dry matter were achieved at the second harvest by such addition to the manure. For the first harvest, no effects were found of marble application. This may be due to the manure being stored for a longer time for the application in spring, whereas manure applied after the first harvest was freshly collected. In open containers, slurry from pigs and dairy cows, digested dairy cow slurry and digestate from a biogas plant (Ecopro) treating sewage sludge, household waste and fish waste was studied. Substrates with or without... |

| Litterbag were used to study the effects of different ploughing depths on decomposition rate of barley straw with different ploughing depths. The burying depth of the litter (13 vs 25 cm) affected the decomposition rate of barely straw more than the different ploughing depths (13 vs 25 cm). From our results we suggest that slowly decomposable organic matter, such as leached barley straw, may be incorporated deeply by ploughing in organic cereal production systems, in order to regulate perennial weeds. In soils with good structure and porosity, the decomposition rate of straw can even be larger with deep ploughing. In dense, clayey soils it is important to be very accurate in ploughing time in order to secure that the ploughing is in fact loosening the... |
