| The total ash content is usually considered to be fairly constant during the composting period, apart from addition of minerals by precipitation and losses by seepage. However, our field trials with farmyard manure have shown that the ash fraction insoluble in hydrochloric acid increased much more than the soluble fraction in the same time. If changes are merely caused by composting intensity (e.g. organic matter degradation), both fractions should be accumulated in the same degree. It is hypothesized that the higher rise of the HCl-insoluble fraction indicates a higher amount of soil material in the heaps at the end compared to the beginning of composting, as the insoluble fraction originates mainly in soil-borne silicates while the soluble fraction is... |

| In 2009 heeft het Louis Bolk Instituut onderzoek verricht naar het gebruik van versgemaaide en ingekuilde maaimeststoffen voor de bemesting van najaarspinazie op het bedrijf van Joost van Strien in Ens in de Noord Oost Polder. Maaimeststoffen zijn een innovatief teeltsysteem (het zgn. “cut-and-carry” systeem) waarbij gemaaide grasklaver of luzerne, gewassen die als bodemverbeteraar een essentiële rol in de gewasrotatie vormen, direct op eigen bedrijf worden ingezet als hulpmest stof i.pv. deze te verkopen als veevoer. Wij concluderen dat door gebruik van het systeem dat op het bedrijf van Joost van Strien is ontwikkeld, doelgericht gebruik kan worden gemaakt van meerjarige vlinderbloemige gewassen. Hierdoor worden zowel het bodemleven en bodemkwaliteit... |

| The aim of the work was to verify the potential of citrus by-products for the production of a quality compost to be used in both conventional and organic farming. Two different composts were produced utilizing Pastazzo (mixture of citrus pulp and skins). One of them, to be used in conventional farming, was prepared adding sludges obtained from citrus industry waste water treatment to pastazzo. The other one, whose final destination was organic farming, was produced without the addition of sludge as starting raw material. Chemical parameters were used to evaluate the characteristics of the final product. Results obtained demonstrated that organic residues from citrus-processing industry could be considered as raw materials for the production of quality... |

| Ce travail a été mené à la ferme expérimentale du Complexe Horticole d’Agadir. Son objectif est d’étudier d’une part le comportement de trois variétés du haricot vert associées à une culture de courgette et d’autre part l’effet d’une fumure organique à base de farine de poisson sur le rendement de la courgette (variété ROBERTA) dans un système biologique. L’essai s’est déroulé sous serre de type delta 9. Pour le premier essai, l’effet de l’association a été testé dans un dispositif qui permet de placer une ligne simple de courgette entre deux lignes de haricot, et de façon à ce que chaque plant de courgette soit entouré par six plants de haricot vert. La densité était de 5000 plants par hectare pour la courgette et de 33333 plants par hectare pour le... |

| Im Ökologischen Landbau ist weicherdiges Rohphosphat als Phospatdüngemittel zugelassen. Die Effizienz von Rohphosphatdüngemitteln wird insbesondere durch den pH-Wert des Bodens sowie die Phosphat- und Ca-Konzentration der Bodenlösung beeinflusst. Zur Förderung und Stabilisierung der Bodenfruchtbarkeit werden die Böden gekalkt, so dass der pH-Wert mineralischer Böden meistens über 6 liegt. Kalkung dient nicht nur der pH-Wert-Stabilisierung, sondern durch die Zufuhr von Ca2+ wird auch die Bodenstruktur gefördert und stabilisiert. Darüber hinaus wirkt die Kalkung aber einer höheren chemischen Löslichkeit der Rohphosphate entgegen. Die daher auf mit Rohphosphat gedüngten Flächen (mit pH über 6) niedrigere Phosphatfreisetzung kann für die Phosphaternährung... |

| Am Sächsischen Landesamt für Umwelt, Landwirtschaft und Geologie (LfULG) in Dresden-Pillnitz wurde im Winter 2017/2018 ein Brutversuch durchgeführt, bei dem der Einfluss der vorherigen Bodenbewirtschaftung auf das N- und S-Mineralisationsverhalten von Hornmehl untersucht werden sollte. Gleichzeitig wurden zwei pelletierte Düngemittel auf Schafwollbasis sowie ein pelletierter Dünger auf Weißkleebasis getestet. Die von einem Schlag, aber 0 (= Freiland), 8 bzw. 17 Jahre unter Gewächshaus-Bewirtschaftung gestandenen Böden zeigten deutliche Unterschiede im Ct-, Nt- und St-Gehalt sowie Nmin-Ausgangs-Gehalt. Überraschender Weise zeigte der Freilandboden im Brutversuch (15 °C) mit umgerechnet knapp 13 kg N/ha pro Woche eine deutlich höhere N-Nachlieferung als... |

| 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. |

| The effect of different organic fertilisers (farm yard manure [FYM]; vermicompost [VC]; plant compost [PC] and integrated compost [INT], i.e. a combination of FYM, VC and PC in a 1:1:1 ratio) on the population and diversity of soil fungi was investigated in a maize-French bean trial. Fungal populations were much higher in organically fertilised plots as compared to the control (CTRL) and showed a decreasing trend in the order FYM>PC>INT>VC>CTRL. Altogether, 122 fungal species and two sterile mycelia were isolated from all the plots of which 25 fungal genera belonged to Deuteromycotina, seven to Ascomycotina, four to Zygomycotina and one to Mastigomycotina. The most common genera isolated from all the plots include Penicillium, Aspergillus,... |

| 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... |

| Organic farms without or with a too low animal livestock try to replace farmyard manure by using plant based organic fertilizers, e.g. legume biomass as green meal or grain meal. When applying such fertilizers, it is necessary to know their nitrogen mineralisation intensity in relation to farmyard manure. In an incubation test over three weeks (25 °C, 45% maximum water holding capacity) alfalfa meal showed a lower and faba bean meal a much higher nitrate N mineralisation than farmyard manure (15 and 69 ug g-1 dry matter, respectively, compared to 25).The largest amount was released from castor meal (99 ug g-1). After one week farmyard manure had the largest N release with 28 ug g-1. |
