| Hoe kunnen veetelers met minder input meer resultaten halen bij snijmaïsteelt? Dat is de centrale vraag van het project “Duurzaam bodembeheer maïs” (BO-31.03-001-003). Veel melkveehouderijbedrijven telen snijmaïs, een gemakkelijk te telen ruwvoergewas met een goede productie van constante hoge kwaliteit. Als zetmeelbron met een ruime energie/eiwitverhouding past het goed in het runderdieet, naast gras en graskuil. De maïsteelt kan echter nadelige effecten hebben voor de bodem door gewasbeschermingsmiddelen en het uit- en afspoelen van nutriënten. Wageningen UR en het Louis Bolk Instituut onderzoeken in opdracht van het ministerie van EZ duurzame en praktisch haalbare verbeteringen en vernieuwingen. Teeltsystemen die zorgen voor een gezonde bodem worden... |

| Pour remédier à la pauvreté des sols maraîchers en matière organique, il est d’usage en cas de reconversion en l’agriculture biologique de faire des apports importants de composts. Aux produits du commerce traditionnellement utilisés s’ajoutent aujourd’hui les gisements nouveaux des composts de déchets verts, économiquement très intéressants mais de composition très différente. L’expérimentation conduite vise à mieux connaître l’évolution de ces apports afin d’optimiser ces pratiques dans un double objectif : améliorer les états du sol et prendre en compte la minéralisation azotée afin de mieux alimenter les plantes, notamment les cultures longues d’été sur lesquelles se posent des problèmes de gestion avec les engrais organiques usuels. L’objectif... |

| Potato seed tubers are usually cut into blocks to reduce seed cost, break dormancy and induce dominance. In chemical farming, the cut surface is usually treated with fungicides to avoid infection. In the present research, the cut surface of the seed tuber blocks was treated with a microbial inoculum mixed into bamboo charcoal powder and dried for a moment. Inoculating and drying the cut trace of seed tuber blocks induced activation of the antioxidant enzymes SOD and POD. Properly drying the cut trace induced osmotic adjustment, leaf turgor improvement, disease resistance and yield increase in the potato crop. The treatments were more effective in the soil with compost applied onto the surface. The treatments with sterilized inoculum were more effective... |

| Pratiche di agricoltura intensiva hanno condotto alla degradazione della risorsa suolo, vale a dire ne hanno diminuito la qualità. Più precisamente, la degradazione riguarda la riduzione della sostanza organica, della stabilità strutturale e della disponibilità di nutrienti nel suolo, con conseguente decremento della produttività. All’interno di un progetto di ricerca in corso, relativo a produzione e impiego di compost in agricoltura biologica, sono previste analisi di fitotossicità su sansa umida denocciolata (SD) poi impiegata in una rotazione farro-cece. L’obiettivo della ricerca è quello di verificare come l’incorporazione al suolo di matrici organiche (M), anche tal quali, può concorrere a mantenere o incrementare la fertilità del suolo ed a... |

| Deze brochure schetst de mogelijkheden voor verbetering van de afzet van pluimveemest in de biologische productieketen. Basis hiervoor vormt het project Kippenmest en Kringloop dat in de periode 2007 - 2011 door het Louis Bolk Instituut is uitgevoerd. Pluimveehouders in Nederland zijn vaak weinig grondgebonden. Daarom moet de mest worden afgevoerd. Afzet is echter niet altijd eenvoudig. Dit komt omdat de samenstelling van pluimveemest niet optimaal is. Vooral de relatief lage N/P- verhouding speelt een goede afzet naar de akker- en tuinbouw parten. Kansen voor Pluimveemest toont dat er goede mogelijkheden zijn om tot een gunstiger N/P-verhouding te komen via de voersamenstelling. Ook via andere wegen kan de afzet van pluimveemest worden verbeterd. Dat kan... |

Es sollten dann pflanzliche Düngemittel bevorzugt werden. Hierzu die Gegenthese: Auf Dauer müssen Nährstoffe aus Abfällen zurück auf den Acker, nicht hochwertige Eiweiße, die auch zur Tierfütterung eingesetzt werden können. Die Suche nach Alternativen zu den Abfällen aus der konventionellen Agrarindustrie sollte in den Gemüsebau-Versuchsbetrieben, Bamberg... |

| The majority of soil organic nitrogen (N) is bound in protein-like compounds and therefore its proteolysis in peptides and amino acids is considered the initial and rate limiting step of N mineralization. Proteolysis of N bound in organic fertilizer and subsequent provisioning for crops is a central element in agro-ecological intensification. Long-term farming system effects on N provisioning from organic fertilizer to crops and its underlying functional microbial communities were analyzed in experiments conducted in soils from the “DOK” system comparison trial (bio-Dynamic, bio-Organic, and “Konventionell”) subjected to optimal and future projected drought scenarios. A plant nutrition experiment using 15N labeled lupine as a fertilizer (green manure)... |

| Adopting measures to increment soil levels of organic matter and biological activity is key when an agrosystem is going to be converted to organic management. Nutrient reserves are increased and more easily mobilized, and soil suppresivity is enhanced. This last aspect is particularly relevant in replantations where chemical disinfection treatments can not be used and plantlets are very sensitive. A field trial is therefore being carried out to study the effects on soil biochemical and microbiological properties of different techniques(disinfectant vegetal cover, organic amendment and biofumigation, with untreated and solarized controls) to prepare the soil for replanting in a citrus orchard in convertion to organic management. This work discusses the... |

| Description and assessment of soil organic matter are usually based on either stock parameters (e.g. Corg, carbon soluble in hot water, particulate organic matter fractions, humic acids, humins etc.) or activity parameters like soil respiration, microbial biomass (CFE, SIR), enzyme activities, Biolog® analysis, incubation tests. Each parameter describes a specific part of soil organic carbon and specific turnover processes in the complex action of carbon mobilization / immobilization. With 3 selected parameters: organic carbon content (Corg), particulate organic matter content (POM) and carbon dioxide development after re-wetting of air-dried soil samples (CO2 flush in 24 h) and their results obtained in a long-term fertilization trial the pros and cons of... |

| In a 22-year-old experiment in Southwest Germany, the effects of different fertilization systems (organic and mineral fertilizers) on permanent grassland were investigated. The effects were investigated under cutting and mown pasture with two grazing periods per year. The experiment had 8 fertilizer treatments and 3 replications, the size of field plots were 25 m2 in area. Dry matter (DM) yields and mineral contents in soil and forage (P, K) were measured. The botanical composition was investigated each second year. Maximum DM yields were obtained by mineral NPK fertilization and a treatment called ‘alternating fertilizer’, with yearly alternating use of farmyard manure, liquid manure and mineral NPK. The application of composted farmyard manure... |

| The aim of this work was to obtain a number of complete soluble compost extracts rich in micronutrients, which can safely be used for fertigation through modern irrigation systems in organic farming system. Evaluation of their effects was conducted on potato crop var. Draga and soil fertility. During the extraction experiment two different composts (Farm compost and Commercial compost) were treated with water to obtain following dilution ratios: 1:5, 1:10, 1:20. Most chemical parameters of the compost extracts generally reflect the chemical composition of the starting material. These six dilutions were applied during the growing season. The control shows the highest tuber yield (22.1 tons/ha) followed by FC20 treatment (21.03 tons/ha). The number of tubers... |

| It is well-known that compost and manure applications to all kinds of soils if these organic materials are mature and composted under favorable conditions result in improved soil fertility and crop production in terms of yield and quality, but because manure is expensive in our region and the application of in-farm production compost for organic lands and farms of Turkey is limited, there is a great and urgent need for demonstrate compost using advantages to soil fertility, plant yield-quality and food safety (Kir 2006). Vegetables account for only approximately 2% of total organic production in Turkey, but there is great potential for growth of organic production for both export and domestic consumption of organic products in our country. Lettuce (Lactuca... |

| Im ökologischen Gemüsebau werden hohe Nährstoffmengen benötigt, um qualitativ hochwertiges Gemüse zu produzieren. Der Nährstoffbedarf kann bisher nicht ausreichend durch ökologisch erzeugte Düngemittel gedeckt werden. Zum Einsatz kommen überwiegend organische Reststoffe aus der konventionellen Landwirtschaft. An dieser Stelle setzte das Forschungsvorhaben mit dem Ziel an, ein stickstoffreiches Düngemittel aus Futterleguminosenschnittgut für den ökologischen Gemüsebau zu entwickeln und in Spinat und Rote Rübe zu erproben. Es sollte junges Schnittgut mit einem C/N-Verhältnis von ≤ 10 geerntet werden, welches nach Einarbeitung in den Boden schnell mineralisiert. Die Untersuchungen gliederten sich in vier Teile. Im ersten Teil der Arbeit wurden in... |

| Problemstellung/Ziele: Die Zusammensetzung mikrobieller Gemeinschaften und deren Funktionen im Boden kann mit Hilfe moderner Techniken beschrieben werden. Diese beruhen u.a. auf der Untersuchung der genetischen Eigenschaften mittels DNA-Analysen, molekularen Markern der Zellmembran oder physiologischer Eigenschaften der Organismen. Die Frage, ob die daraus ableitbare strukturelle und funktionelle Vielfalt von mikrobiellen Gemeinschaften ein Kriterium für Bodenqualität sein kann, ist Gegenstand wissenschaftlicher Diskussion. Der Nachweis eines Zusammenhangs von mikrobieller Diversität und wichtigen ökologischen Funktionen des Bodens, die auf mikrobiellen Prozessen basieren, steht noch aus. Das Ziel der vorliegenden Untersuchung war, drei Ansätze zur... |
