| Ikke noget eller ikke for meget vil det mest nærliggende svar vel være for de fleste økologiske planteavleres vedkommende. For den konventionelle husdyrproducents vedkommende vil svaret formentlig være lige det modsatte. - nemlig at han sidder på en guldgrube. Alle svar kan på den ene side være fuldstændigt rigtige, men de kan på den anden side også være helt forkerte. Jeg vil i det efterfølgende prøve at forklare hvad jeg mener med ovenstående tvetydige svar på spørgsmålet i overskriften. |

| Çalışma 2001-2010 yıllarında Ege Üniversitesi Ziraat Fakültesi Menemen Araştırma Uygulama ve Üretim Çiftliğinin “organik” sertifikalı alanında yürütülmüştür. Ana bitki olarak Yalova Yağlık 28 kapya biber çeşidi, ön bitki olarak da fiğ, kırmızı lahana, marul, bakla, brokkoli, kereviz, karnabahar ve bezelye kullanılmıştır. Organik tarım yönetmeliğine uygun yürütülen çalışmada 9 yıllık süre içerisinde ön bitkilere göre elde edilen biber verim değerleri ile bazı kalite özellikleri belirlenmiştir. Her ön bitki üretiminden sonra alınan toprak örneğinde de organik madde ve bitki besin elementlerindeki değişim incelenmiştir. Çalışmadan elde edilen verilere göre, fiğ ön bitkisi desteğindeki geçiş sürecinde yüksek oranlarda (4352 kg da-1) elde edilen biber toplam... |

| Die integrierte Biogaserzeugung in Ökobetrieben zieht vielerlei agronomische Auswirkungen auf das gesamte Betriebssystem nach sich. Herkömmliche Wirtschaftlichkeitsanalysen vernachlässigen jedoch das ökonomische Potential dieser Effekte. Dieser Beitrag verfolgt daher einen ganzheitlichen Bewertungsansatz, der diese monetären Zusatzleistungen mit einbezieht. Modellsimulationen ökologischer Fruchtfolgesysteme, die insbesondere eine veränderte Stickstoff-Effizienz berücksichtigen, zeigen mögliche Ertragssteigerungen der Marktfrüchte und eine verbesserte Wirtschaftlichkeit des Ackerbaus durch die integrierte anaerobe Vergärung sowohl in viehlosen als auch in viehhaltenden Ökobetrieben auf. |

| This report was presented at the UK Organic Research 2002 Conference. Farmgate nutrient budgets have been calculated for Cu, Co and Mo for six farms in NE Scotland. All five livestock farms studied had a positive balance for Co, one showed a negative balance for Cu and two showed negative balances for Mo. The stockless farm studied showed a positive balance for Cu but negative balances for Co and Mo. These balances were calculated for a one-year period only and may thus have been strongly influenced by one-off purchases e.g. calcified seaweed. Future work will calculate budgets over whole rotations to provide a clearer picture of the long-term sustainability of trace element use on organic farms. |

| Organic farming systems with restricted access to animal manure often experience decline in soil P concentrations. Nutrients should be cycled in society to maintain the long-term fertility of agricultural soil. One option for this may be precipitation of struvite (magnesium-ammonium phosphate) from sewage treatment plants, to be Applied as fertiliser. Struvite produced in a Norwegian sewage plant (Hias IKS)significantly increased yield levels and soil P concentrations, when applied in one season (2018) in a long-term experiment comparing two levels of manure application at Tingvoll research farm, NW Norway. Struvite has been proposed by the Expert Group EGTOP to be included in Annex 1, listing permitted fertiliser inputs in organic farming. However, a... |

| The Biodynamic Research Institute in Järna developed a two-phase on-farm biogas plant. The plant digests manure of dairy cattle and organic residues originating from the farm and the surrounding food processing units containing 17.7-19.6 % total solids. A new technology for continuously filling and discharging the hydrolysis reactor was developed and implemented. The output of the hydrolysis reactor is separated into a solid and liquid fraction. The solid fraction is composted. The liquid fraction is further digested in a methane reactor and the effluent used as liquid fertiliser. Initial results show that anaerobic digestion followed by aerobic composting of the solid fraction improves the nutrient balance of the farm compared to mere aerobic composting.... |

| During 2003 and 2005, plant growth promoting effects of two Bacillus strains OSU-142 (N2-fixing) and M3 (N2-fixing and phosphate solubilizing) were tested alone or in combinations on organically grown primocane fruiting raspberry (cv. Heritage) plants in terms of yield, growth, nutrient composition of leaves and variation of soil nutrient element composition in the province of Erzurum, Turkey. The results showed that Bacillus M3 treatment stimulated plant growth and resulted in significant yield increase. Inoculation of raspberry plant roots and rhizosphere with M3 and/or OSU-142 + M3, significantly increased yield (33.9% and 74.9%), cane length (13.6% and 15.0%), number of cluster per cane (25.4% and 28.7%) and number of berries per cane (25.1% and... |

| Det övergripande målet med forskningsprojektet är att skapa en bas för utveckling av odlingssystem, för att bl.a. finna lösningar på kväveproblematiken i lerjordssystem. Målet är att uppnå ett lönsamt och uthålligt jordbruk på dessa jordar. Detta ska göras genom att kvantifiera och följa upp olika förlustvägar för växtnäring i några olika odlingssystem på lerjord och bestämma förhållanden i mark och gröda som påverkar omsättningen av växtnäring, främst kväve. Projektet ska visa på möjligheter att i dessa system styra växtnäringstillgänglighet och förluster, på möjligheter att förbättra odlingsbetingelser på struktursvag lerjord samt visa på lösningar av vattenfrågor i odlingslandskapet och genomförs på lerjord som ska täckdikas.

| A study was carried out in nineteen vineyards of five countries, well representative of major viticultural districts, which showed areas with fertility problems, consequence of strong soil erosion occurred during either pre-planting or ordinary cultivation. The comparison between degraded and non-degraded areas highlighted that the soil features limiting water nutrition and enhancing potential water stress were the most frequent discriminant soil conditions. Low nitrogen availability was the second most important cause of soil malfunctioning, together with low organic matter content. The degradation was also reflected in the very low values of the C/N ratio, pointing to a difficulty of microbiota in synthetizing humus. Other limiting factor were excessive... |

| Usage of organic fertilizers and agricultural service crops (ASC) are the main tools to ensure soil fertility to obtain high quality organic vegetables. The most popular used ASCs are green manure, catch-crop, and living mulch. Efficiency of ASC crops under Latvia agro-ecological conditions for vegetable growing has not been investigated till now. Field trials where established in the Institute of Agricultural Resources and Economics during the season of 2015/2016 in Dižstende, Latvia with the aim to clarify the influence of ASC application on cabbage and onion crops yield and compare with traditional soil management systems: (i) green manure - in which ASC biomass of winter rye (Secale cereale L.) and winter rape (Brassica napus L.) was incorporated in... |

| Nowadays only eight percent of the cultivated field area is used for organic farming. The Ministry of Agriculture and Forestry has published the guidelines for the program of organic farming to diversify the supply and the consumption of organic food. The aim is to increase organically arable land to 20% by the year 2020.The demand of organic fertilizer products is strongly increasing. Interest in forestry by-products (ash, bark, zero fiber, etc.) for use in organic production has recently been exceptionally high. For example, development of pelleted fertilizers with zero fiber, ash and a nitrogen-containing fertilizer material is in progress.The ash fertilizer contains many valuable nutrients in fairly optimal ratios: these include phosphorus, potassium,... |

| The effectivity of Inhana Rational Farming (IRF) Technology towards energization of plant physiological functioning was evaluated in comparison to other organic packages of Practice under FAO-CFC-TBI Project at Maud Tea Estate, Dibrugarh, Assam, India during 2008 to 2013. The study area lies in 27.26. N latitude and 95.12 E longitude covering a total area of 154.58 ha area with level to nearly level landscape. The experiment was laid down as per randomized block design (RBD) with 8 treatments replicated 3 times. The treatments included available two organic methods viz. Biodynamic Farming (BD) and Inhana Rational Farming (IRF) (developed by Dr. P. Das Biswas, Founder, Inhana Biosciences, Kolkata) as well as organic inputs viz. vermicompost,... |
