| In order to acquire more information about green manure practices in the Mediterranean environment, green-manure crops from two seasons (2003/2004 and 2004/2005) were compared and evaluated in two agroecosystems (“Old Organic” and “Young Organic”) of the Montepaldi Long Term Organic Experiment in Tuscany. Data collection included green manure crop (biomass, weeds competition capacity, N and C content), weed biodiversity on maize, and soil fertility characteristics over three periods (in October before sowing the green manure, in April before the incorporation of the green-manure in the soil, and in September at the maize harvest). The different green manure species produced no significant effects on the weeds and N% and C% in the soil. Weeds... |

| Both winter wheat and spring wheat have the potential for producing grain of bread wheat quality under North European conditions. The two crops may due to their different growth length respond differently to previous use of green manure and to the soil organic matter content. To compare winter wheat and spring wheat for their ability to produce quality grain for bread production, both crops are included in a long-term experiment (LTE) at Askov Experimental Station. The LTE provides a unique platform for such comparison, as the two crops can be grown under identical conditions regarding previous management, soil and climate. The bread wheat experiment is part of the project AGronomical and TEChnological methods to improve ORGanic wheat quality (AGTEC-Org)... |

| In Nordic conditions, soils are frozen during winter, affecting the decomposition rates of crop residues. Hence, the decomposition rates of above- and underground biomass and the dynamics of the N and C released into the soil were studied in trials focused on green manure crops. The decomposition of the residue and N release from the residue varied among the five species of legume tested. There was a marked difference in decomposition rates between shoots and roots, which may also be explained by the differences in the chemical composition of the residue. The shoot residue decomposes rapidly and it serves as a source of N for the subsequent crop. The root residue decomposes more slowly and this had a positive effect in a crop rotation in the second year.... |

| Introduction: Grass-clover mixtures show many benefits for sustainable agriculture. In the Netherlands, organic arable and livestock farmers often work together in a so-called partner farm concept: the arable farms grow one-year grass-clover leys to widen their crop rotation and as fodder for a livestock farm in exchange for manure. The aim of this research was to investigate the effect of different grass-clover mixtures and monocultures in a one-year ley on both aboveground and belowground parameters in light of the benefits of the ley for livestock farms, arable farms and biodiversity |

| Die Nitrogeneffektivität im Jahr 2010 wird auf zehn ökologisch wirtschaftenden Milchviehbetrieben und zehn konventionellen untersucht. Vorläufige Resultate werden präsentiert und die verwendete Methode diskutiert. Die Effektivität wird aus Netto-Ex- durch Netto-Import berechnet. Die Nitrogenfixierung durch Klee hatte großen Einfluss auf die berechnete Nitrogen-Effektivität. Da es große Variation von Jahr zu Jahr und Unsicherheit bei dem Anschlag für die Nitrogenfixierung (durch Estimierung der Rauhfuttererträge, des Kleeanteils und wie viel Nitrogen pro Kilogramm geerntetem Klee fixiert wurde), sollten die angegebenen Werte für die berechnete Nitrogen-Effektivität nicht als absolut angesehen werden. Die Unterschiede in der Flächenausstattung, dem... |

| Prosjektet “Forsøk med fermentering av husdyrgjødsel» (2016-2018) prøver ut tilsetning av effektive mikroorganismer (EM) i dyrerom og gjødsellagre på noen gårder i Norge. Et kontrollert forsøk ble gjennomført på Tingvoll vinteren 2017-18. Uttrykket «effektive mikroorganismer» ble først brukt i Japan, der forskere isolerte og dyrket opp stammer av ulike jordboende sopp og bakterier, og prøvde dem ut i ulike kombinasjoner som tilsetning til dyrka jord. Ideen var å utkonkurrere den stedlige mikrofloraen og få sunnere planter og bedre avlinger. Metoden har fått vid anvendelse i Asia, og knyttes ofte til begrepet «nature farming» eller «Kyusei nature farming». Også i Europa er det nå mange produkter på markedet som inneholder EM. Det selges midler for å... |

| Nitrate leaching losses from arable cropping systems cause severe damages to the environmental services worldwide. There is a considerable need for methods that allow rapid, easy and area covering detection of nitrate leaching to guide N management. We used three years of data from the 5th cycle of a long-term crop rotation experiment in Denmark to quantify the relationships between nitrate leaching in autumn and winter and field conditions in autumn as defined by three vegetation indices [VIs; Ratio Vegetation Index (RVI), Normalized Difference Vegetation Index (NDVI), Ratio Red Edge (RRE)] in autumn. Following cereal crops, catch crops significantly reduced nitrate leaching in autumn and winter, whereas this was only the case for one out of the three... |

| In recents years, organic farming is expanding in Southern Italy and in the Mediterranean area, due to interest of consumers and EU agricultural policies. Evaluation of organic farming system introduction on soil quality and fertility status should be taken into account in order to define medium-long term environmental and agricultural strategies, on both locol and national scale. Soil physical, chemical and biological parameters represent effective tools to evaluate soil quality and changes in soil fertility status, as a consequence of different agronomic management (i.e. organic vs coventional). The aim of this work was to compare soil fertility of conventional and organic managed citrus Orchards, using specific soil system descriptors. The research was... |

| • Deep roots may be important for uptake of NO3- by annual crops. A field experiment with the deep rooted crop curly kale (Brassica oleracea L. convar. acephala (DC.) Alef. var. sabellica L.) was performed to investigate root distribution and N uptake in deep soil layers. • Root distribution was investigated by use of minirhizotrons and root extractions to 2.4 m depth. The capacity for crop N uptake was studied by deep 15NO3- placement followed by analysis of plant 15N content after 3-30 days. • The atom percent 15N excess (APE) of plant samples was of similar size after uptake of 15N placed at depths in the range of 0.4-2 m. Root colonisation and start of 15N uptake were synchronized in 2.4 m depth. • The deep roots had higher inflow of 15N compared... |

| Maintaining sufficient soil phosphorus (P) levels for non-limiting crop growth is challenging in organic systems since off-farm inputs of P are restricted. This study assessed the status of P on organic farms in Europe using soil test results for extractable P. Data was obtained from published literature, unpublished theses, and various national and regional databases of soil test values. Most of the data (15,506 observations) came from field scale soil tests, but in some cases (1272 observations) values had been averaged across a farm. Farm scale and field scale data were analysed separately and the impact of farm type (arable, dairy, grassland, horticulture, mixed, poultry, unknown) was assessed. Soil test results were assigned to P classes from very low... |

| The effectiveness of ‘Effective Microorganisms’ (EM) was investigated in a four years field experiment (2003-2006) at Zurich, Switzerland. The experiment was designed to enable clear differentiation between effects of the microorganisms in the EM treatments (Bokashi and EMA) and its substrate (sterilized treatments). Crop yields and soil microbiological parameters as soil respiration and microbial biomass were determined. The EM treatments showed no effect on yield and soil microorganisms which were caused by the EM microorganisms. Observed effects could be related to the effect of the carrier substrate of the EM products. The sampling time showed stronger effects on soil microbial biomass and soil respiration compared to the effect of the treatments.... |
