| Im ökologischen Landbau stellen der Beikrautdruck, die N- und Humusversorgung zentrale Probleme der Fruchtfolge dar. Ertrag, Ertragssicherheit und der Pflegeaufwand werden davon direkt bestimmt. Leguminosenhaltige Grünbrachen in der Fruchtfolge mindern besonders den Unkrautdruck und verbessern die Humusbilanz. Ihre N-Wirkung fällt dagegen bisher unbefriedigend aus, da der oft kurzfristig hohe N-Bedarf der Gemüsepflanzen nicht gedeckt werden kann. Auch über Winter abfrierende Gründüngungspflanzen zeigen oftmals nur eine schwache Düngerwirkung, weil die Gemüsepflanzen nur ein geringes Wurzelsystem haben, das keinen Zugang zu dem tiefer im Boden verlagerten Stickstoff hat. Es soll deshalb untersucht werden, ob durch den Anbau einer Gründüngung in Verbindung... |

| A five-year experiment results, have shown that fertilizer amendments are needed for preserving the nutrient balance in the soil. A combination of cattle and green manure, crop rotation and other organic farming practices, with chemical fertilizer amendments could suppose a sustainable solution for maintaining a correct nutrient balance in the soil in long term, better than both farming systems, conventional and organic, by separate. |

| In het kader van het project Minder en Anders Bemesten is op het bedrijf van Jan en Hans van Lierop vervolgonderzoek uitgevoerd. In een veldexperiment in herhalingen is getracht de productie van courgette gelijkmatiger in het seizoen te verdelen door op twee peilers te steunen: een bescheiden bemesting om de productie in het begin van het seizoen te verhogen, en grasklaver als voorvrucht om de productie verderop in het seizoen te verhogen. De resultaten tonen dat deze aanpak werkt: met een relatief kleine bemesting is er geen sprake van een verlaagde opbrengst in de eerste helft van de productieperiode. Verder is de bodemstructuur verbeterd door de grasklaver en is de mestgift lager dan anders het geval zou zijn geweest. |

| 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... |

| In this project, located at Winklhof, a comparison between organic and conventional farming is done. The field trial combines a crop rotation with two levels of fertilisation intensities (one is 1.0 LU ha- and the other is 1.8 LU ha-1). The fertilisation-systems are stable-manure and liquid manure, the treatments were done organically. The aim of this project is to find out which production system is better for the environment in spite of crop yield, product quality and leaching losses. The last parameter was measured in lysimeters. A high amount of yearly precipitation could account the high amount of seepage water. Consequently the leaching losses of both production systems could be compared. |

| Sob manejo orgânico, foram avaliados, em Seropédica, RJ, os sistemas de plantio direto da berinjela(Solanum melongena) nas palhadas de Crotalaria juncea (crotalária), Pennisetum glaucum (milheto, cv. BRS 1501)e vegetação espontânea (pousio), em comparação com o plantio convencional (aração e gradagem ou enxada rotativa). Simultaneamente, foram avaliados três tipos de cultivo: berinjela em monocultura, em consórcio com crotalária e em consórcio com caupi (Vigna unguiculata, cv. Mauá). Não houve diferença entre os sistemas de plantio direto e convencional quanto à produção comercial da berinjela. A palhada da crotalária foi mais eficiente que a do milheto e do pousio para cobertura morta do solo e conseqüentemente o controle de plantas espontâneas foi maior.... |

| Zur Erzeugung von ökologischem Gemüse ist in den meist viehlos wirtschaftenden Betrieben zusätzlich zur Stickstoffgewinnung durch regelmäßige Leguminoseneinsaaten eine weitere Zufuhr stickstoffhaltiger Dünger erforderlich. Dabei wird aufgrund der BSE-Krise vermehrt auf Dünger vegetabiler Herkunft zurückgegriffen, wobei sich die Verwendung pflanzlicher Stoffe mit hinreichend hohem Stickstoffgehalt anbietet. Jedoch stellt sich auch hier - vor allem vor dem Hintergrund der durch die Richtlinien der Anbauverbände begrenzten organischen Düngerzufuhr (110 kg/ha) - die Frage des Abbauverhaltens dieser Dünger in Abhängigkeit von Standort und Witterung und dem damit verbundenen Nährstofffluss. Denn gerade im zeitigen Frühjahr und im Herbst sind aufgrund der... |

| Biodynamic farming is the oldest organic farming movement in Germany. Since Dr. Rudolf Steiner’s “Course on Agriculture” held in 1924, the number of biodynamic farmers in Germany has grown continuously, with 1,317 farmers currently producing on 47,592 ha. One of the most distinctive aspects of biodynamic farming is the use of the so-called biodynamic preparations, which are applied in homeopathic doses. Biodynamic preparations are supposed to improve plant growth and food quality, minimising natural variations. This paper deals with investigations of influences of these preparations and increased manure application on potato yield and tuber quality. The results are drawn from extensive research on organic potato production carried out by several institutes... |
