| Mikronährstoffe haben wesentliche Funktionen im pflanzlichen Stoffwechsel und sind vor allem für die Toleranz gegenüber abiotischen und biotischen Stressfaktoren von Bedeutung. Als Hinweis auf die Mikronährstoffversorgung im ökologischen Landbau wurden Boden- und Pflanzenproben des Langzeit-Düngungsversuches Darmstadt untersucht (Beginn: 1980; Sand-Braunerde, 9,5°C und 590 mm Jahresdurchschnitt, Varianten: Rottemistdüngung mit und ohne Anwendung der biol.-dyn. Präparate und Mineraldüngung in jeweils drei Stufen). Es wurden die Gesamtgehalte an Mn, Zn, Cu, und Fe des Bodens, die pflanzenverfügbaren Mengen sowie die Konzentrationen dieser Nährstoffe in Kartoffelblättern untersucht. Die organisch gedüngten Parzellen enthalten größere Mengen (5,8 mg Zn kg-1... |

| In der vorliegenden Arbeit wurde ein viehloses Anbausystem im Rahmen des Ökologischen Landbaus hinsichtlich des Einflusses der Fruchtfolgezusammensetzung und der Düngung auf die Stickstoffdynamik und -ernährung, die Pflanzenentwicklung und die Stickstoffverluste durch Nitratverlagerung im Boden untersucht. Untersuchungsgegenstand war der im Herbst 1991 am Fachgebiet Ökologischer Landbau der Universität Gesamthochschule Kassel angelegte Dauerversuch mit dem Thema Viehloser Ökologischer Landbau. Die Fruchtfolge dieses Versuchs bestand im Untersuchungszeitraum aus einer einjährigen Kleegras-Grünbrache und den drei nachfolgenden Marktfrüchten Kartoffeln, Winterweizen und Sommergerste. Nach Umbruch der Grünbrache im August und nach der Weizenernte erfolgte ein... |

| Die tägliche Vorlage von Raufutter in frischer, silierter oder getrockneter Form ist gemäß EG-Öko-Verordnung (EWG-Nr. 889/2008) für schweinehaltende Betriebe vorgeschrieben. Auf vielen Betrieben wird jedoch diese Vorgabe nicht oder nur partiell eingehalten. Damit bleibt auch das den Raufuttermitteln innewohnende Potential im Hinblick auf Nutzung betriebseigener Ressourcen, Verbesserung des Tierwohles durch Beschäftigung, Sättigung und Verminderung aversiven Verhaltens sowie hinsichtlich der Förderung der Tiergesundheit ungenutzt. Um den landwirtschaftlichen Betrieben die Einhaltung der gesetzlichen Vorgaben und die Nutzung der Potentiale zu erleichtern, soll die aus der Milchviehfütterung bekannte Totale Misch-Ration (TMR) als Fütterungstrategie für... |

| tEggs of Ascaris suum from pigs are highly resistant and commonly used as a conservativeindicator of pathogen inactivation during slurry storage. Eggs of Ascaridia galli, the poultryascarid, are also known to be highly resistant but the suitability as an indicator of pathogeninactivation has never been tested. Pig slurry has to be stored for several months to inac-tivate pathogens but chemical treatment of slurry may reduce this time. The suitability ofA. galli as an indicator of slurry sanitation was tested by comparing the survival of eggsof A. suum and A. galli in pig slurry. In addition, the effect of urea treatment on inactiva-tion of ascarid eggs in relation to storage time was also tested. Nylon bags with 10,000eggs of either species were placed in... |

| Kvickrot (Elytrigia repens (L.) Desv. ex Nevski) är ett flerårigt ogräs som är vanligt förekommande i svenska odlingsmarker. Innan kemisk totalbekämpning med glyfosat var kvickrot ett vanligt problem i lantbruket. Ogräset kontrollerades då med intensiv jordbearbetning. Idag är kvickrot ett viktigt ogräs i ekologisk odling och i system med reducerad jordbearbetning. Dock måste kvickrot fortfarande anses vara ett problem i konventionella system eftersom glyfosat måste användas återkommande för att slippa konkurrenseffekterna från kvickrot. Detta arbete är ett delprojekt som ingår i ett större projekt som syftar till att utveckla ekologiska odlingssystem som inte är lika beroende av jordbearbetning för att kontrollera kvickrot som dagens system. I arbetet... |

| Dette projekt har fokuseret på direkte bekæmpelse af tre skadegørere i økologisk ribs og solbær, nemlig den lille frostmåler Operophtera brumata, L. (Lepidoptera: Geometridae), viklere, primært hækvikler Archips rosana (L.) (Lepidoptera; Tortricidae) og ribsbredvingemøl Lampronia capitella (Clerck) (Lepidoptera; Prodoxidae). Behandlinger blev testet i en mark på 0,78 ha opdelt mellem solbærsorterne Ben Hope og Titania og i ribssorten Rovada. Vi anvendte et randomiseret blok design. I 2011 sammenlignede vi behandlinger med insektsæbe, rapsolie og Bacillus thuringiensis i Rovada og Titania. I Ben Hope sammenlignede vi blandinger af disse midler samt blanding med pyrethrum. I 2012 fortsatte undersøgelserne. Dette år indgik neem, sammen med B thuringiensis og... |

| Underutilised crops are offering opportunities to diversify and improve farming and food systems as a response both to climate change and to social changes in food culture and uses. The choice of seed greatly determines farming practices and all stages of the food supply chain right up to the consumers’ plate. Based on DIVERSFOOD outcomes, this Booklet #6 proposes a number of thought-provoking concepts, methods and tools. It aims to inspire stakeholders who wish to develop diversity in food systems, presenting 10 novel ideas and approaches that support innovation embedding diversity in food systems from the field to the plate. |

| In the area of potato production, targeted research solving concrete and actual problems of potato producers runs on Czech University of Life Sciences in Prague. In the last few years, we were focused on the production of new potatoes designated for early harvest, and we were focused on capitalization of yielding and qualitative characteristics of colored potato variety. These findings were further utilized and transferred to the system of organic farming. Firstly, we watched the influence of organic farming on yield and quality of tubers. Ecological ways of cultivation had strong negative influences on yield (decrease of 36%). From qualitative characteristics, organic farming increased the content of polyphenols by 10.2%, decreased the content of nitrates... |

| The application of sewage sludge to agricultural land, a common practice to recycle nutrients in the past, is currently prohibited in organic farming due to the risk of soil contamination from pollutants (e.g. toxic and potentially toxic elements, persistent organic pollutants, etc.). Incineration or disposal to landfill of dewatered sludge is costly, leads to greenhouse gas emissions, and eliminates the possibility of nutrient recovery, especially phosphorus. Options to treat dry organic matter are combustion and gasification, among other technologies to produce ashes or chars and to recover the residues for nutrient recycling. Dependent on the technology applied as well as the input material, nutrient concentrations and concentration of contaminants vary... |

| Background and objectives Two pathogens growing on the same leaf compete for the same resources, i.e. space and plant nutrients. This may lead to density dependent disease development. The pathogens may also influence each other directly such that the influence of one on the other is more complex than a simple function of the area of the other pathogen. Different interaction types are, for example, competition, mutualism and exploitation. The importance of such interactions for epidemics of simultaneously occurring pathogens has received little attention. The objective of this study is to investigate the simultaneous epidemic development of Rhynchosporium secalis (causing scald) and Drechslera teres (causing net blotch) on spring barley under field... |

| Das Umbrechen einer Wiese auf maximal 10 cm Tiefe ist eine grosse Herausforderung. An einer Maschinenvorführung des FiBL wurden zwei Pflugmodelle (Överum Variflex, Rumpstad Stoppelploeg), zwei Flachgrubber (Treffler TG 300, Horsch Terrano 3 FX) sowie zwei zapfwellengetriebene Geräte (Rath Geohobel 230, Howard Rotavator 500) im Einsatz verglichen. Alle Maschinen konnten unter den gegebenen Bedingungen die Kunstwiese auf einer Tiefe von maximal 10 cm umbrechen, lieferten jedoch unterschiedliche Resultate. Der Film zeigt, wie die verschiedenen Geräte die Aufgabe bewältigen. Welche Maschine auf welchen Betrieb passt, hängt stark von den Bodenverhältnissen, dem Unkrautdruck und den angebauten Kulturen ab und muss gut überlegt sein. Technische Daten zu den... |

| In many countries, cotton is traditionally intercropped with other plants in order to increase yields and to control pests. We tested the effects of intercropping cotton (Gossypium barbadense L.) and basil (Ocimum basilicum L.) during one field season on pest infestation, yields, and economical parameters in the Governorate of Fayoum, Egypt. Basil, which is known for its repellent effect on various insect pests, was mixed with cotton in three different intercropping rates (no, medium and high basil area fraction) and two row distances (60 and 90 cm) using a substitutive design with four replicates. Compared with the non-intercropped plots, cotton-basil intercropping significantly reduced total pest infestation and led to a 50% reduced abundance of the pink... |
