| Der weltweit einmalige Langzeitversuch „DOK“, der die drei Ackerbausysteme biologisch-dynamisch, organisch-biologisch und konventionell vergleicht, feiert Geburtstag. Paul Mäder, Hans-Martin-Krause und Andreas Fliessbach fassen die spannendsten Ergebnisse zu Boden, Artenvielfalt, Klimawirkung, Ertrag und Effizienz aus 40 Jahren DOK zusammen. |

| The aim of the present study was to examine decomposition of plant material (maize straw, green and rooibos tea) in stratified soils of the long-term tillage experiment, established in 1999 and shifted from conventional to organic farming system in 2015. The plowing in conventional tillage (CT) has been done by moldboard plow 20 cm deep, while in minimum tillage (MT), soil disturbance has been up to 10 cm deep by a Special disc harrow. More than 15 years of long term Minimum tillage, with reduced soil disturbances and improved residue management, resulted in stratification of soil organic carbon and nutrients with highest concentrations in the very topsoil. |

| P. fluorescens is used in agriculture and horticulture as a plant growth promoting rhizobacterium. It colonizes root surfaces effectively and excretes compounds that are influencing plant nutrient uptake and plant health. Soils with different initial biological fertility were analysed 18 and 60 days after inoculating the freshly sown wheat plants with a suspension of a rifampicine tolerant strain of P. fluorescens CHA0, in order to evaluate its survival and lasting effect on soil microbial biomass. P. fluorescens had a lasting effect in soils with low initial biomass, but no lasting effects were found in biologically active soils. |

| Viie katseaasta (2012–2016) keskmised tulemused näitavad, et võrreldes tavasüsteemidega on maheviljelussüsteemidel eelised kestlikuks taimekasvatuseks. Viljelussüsteemi mitmekesistamine vahekultuuride ja lisaks veel kompostitud veisesõnnikuga, võimaldab oluliselt parandada mulla omadusi. Tõusis mulla mikroobide aktiivsus, mulla orgaanilise süsiniku ja üldlämmastiku sisaldus. Mulla mikroobide aktiivsuse ja üldlämmastiku sisalduse vahelised seosed aga vajavad jätkuvaid uuringuid. |

| In 1974, the Swiss Federal Office of Agriculture (BLW) charged the former Federal Research Station for Agricultural Chemistry and Hygiene of Environment (FAC, Bern-Liebefeld) to set up a field trial in collaboration with the FiBL in order to compare the performance of organic farming systems.When FAC-Liebefeld was shut down, the Swiss Federal Research Station for Agroecology and Agriculture (FAL-Reckenholz) took over the responsibility for the DOK trial in close cooperation with FiBL. The DOK-long term trial - unique in its conception - compares the consequences of bio-organic, bio-dynamic and conventional farming systems in a randomised plot trial that has no other equivalent. Experimental samples are used by many other laboratories to develop new... |

| Models for simulating nitrogen leaching are often based on simulations of a number of individual processes in the soil, such as turnover of organic matter, nitrogen mineralisation and immobilisation, nitrification, denitrification etc. It has been found that the models used under Danish conditions (DAISY and/or FASSET) have some limitations especially concerning the turnover of organic matter with implications on e.g. soil respiration. Therefore, the models are being modified and for calibration of the model measurements of in situ soil respiration using a portable CO2-analyser, nitrogen mineralization using a field incubation technique and N2O emission using a static chamber method, were carried out during the growing season 2001. The measurements were... |

| Fungal entomopathogens are seemingly ubiquitous in soils. An increasing number of surveys around the world have shown that ascomycete fungi from the Hypocreales can be isolated from soils of many habitats. Based on morphological characteristics of the fungi some patterns of distribution have emerged. However, recent developments in molecular characterization of entomopathogenic fungi have revealed significant new insights into the distribution of genetic groups of some taxa, including Beauveria spp, and possible restrictions to certain habitats. I will present and discuss some of these distribution patterns and include new findings which indicate that some fungi are restricted to underground lifestyles while others cycle between below- and aboveground... |

| The effect of different organic fertilisers (farm yard manure [FYM]; vermicompost [VC]; plant compost [PC] and integrated compost [INT], i.e. a combination of FYM, VC and PC in a 1:1:1 ratio) on the population and diversity of soil fungi was investigated in a maize-French bean trial. Fungal populations were much higher in organically fertilised plots as compared to the control (CTRL) and showed a decreasing trend in the order FYM>PC>INT>VC>CTRL. Altogether, 122 fungal species and two sterile mycelia were isolated from all the plots of which 25 fungal genera belonged to Deuteromycotina, seven to Ascomycotina, four to Zygomycotina and one to Mastigomycotina. The most common genera isolated from all the plots include Penicillium, Aspergillus,... |

| En tung og knoldet jord er vanskelig at bearbejde. Det kan medføre et dårligt såbed og dårlig fremspiring. Og da en sådan jord også har få porer begrænses transporten af vand og ilt til planternes rødder. Herved forringes leveforholdene smådyr og mikroorganismer og der bliver en dårligere forsyning med næringsstoffer til planterne. For at få et godt såbed skal jorden have en god struktur – den skal gerne danne krummer (aggregater). De bygges op af jordens grunddele eller 'primærpartikler' ler og sand. Til at binde primærpartiklerne sammen kræves bindemidler. I danske jorde er biologiske bindemidler de vigtigste. Der findes to slags. Det ene er klisterstoffer, der dannes af planterødder, bakteri-er og svampe. Det andet er svampetråde (hyfer), der... |

| Organic farms without or with a too low animal livestock try to replace farmyard manure by using plant based organic fertilizers, e.g. legume biomass as green meal or grain meal. When applying such fertilizers, it is necessary to know their nitrogen mineralisation intensity in relation to farmyard manure. In an incubation test over three weeks (25 °C, 45% maximum water holding capacity) alfalfa meal showed a lower and faba bean meal a much higher nitrate N mineralisation than farmyard manure (15 and 69 ug g-1 dry matter, respectively, compared to 25).The largest amount was released from castor meal (99 ug g-1). After one week farmyard manure had the largest N release with 28 ug g-1. |

| Learning how to manage beneficial soil biological processes may be a key step towards developing sustainable agricultural systems. We designed a conceptual framework linking soil management practices to important soil-life groups and soil fertility services like nutrient cycling, soil structure and disease suppression. We selected a necessary parameter set to gain insight between management, soil life and soil support services. The findings help to develop management practices that optimise yields, soil fertility and biodiversity in organic farming. |

| Le projet européen Resolve vise à restaurer un fonctionnement du sol optimal dans des parcelles de vigne en AB souffrant de problèmes de vigueur. Une première étape est de caractériser des zones de faible vigueur ou zones dégradées dans des parcelles à travers différents paramètres relatifs à la vigne, au sol et à son fonctionnement. Les variations de stress hydrique supporté par la vigne ainsi que les rendements et la qualité des baies sont les premiers indicateurs qui ont été mesurés. Dans un second temps, des analyses de sol approfondies et conduites dans les différents horizons permettent d'apporter un premier éclairage sur les facteurs responsables de la dégradation du sol. Enfin, la biodiversité du sol, en particulier les êtres vivants associés au... |
