O sistema de manejo pode afetar a disponibilidade de nutrientes para as plantas, em decorrência do sistema de rotação de culturas e da quantidade de resíduo vegetal presente na superfície do solo. O objetivo deste trabalho foi avaliar a quantidade de nitrogênio (N) e fósforo (P) acumulados no tecido vegetal de aveia preta, trigo, centeio, ervilhaca, nabo e tremoço azul, além de verificar seu estado nutricional de N e P. O experimento esta instalado no Instituto Agronômico do Paraná (IAPAR) em Pato Branco, Paraná, em um Latossolo Vermelho aluminoférrico. Em maio de 2011 os tratamentos foram semeados, sendo seis plantas de cobertura: trigo, aveia preta, centeio, ervilhaca, nabo forrageiro e tremoço azul cultivados sob Sistema Plantio Direto (SPD) e Sistema... |

The soil management systems cause changes to the aggregation and the stock of soil organic matter (SOM). The aim was to evaluate the influence of the winter cover crops and the tillage systems in aggregation and carbon (C) stock in soil and SOM fractions. The experiment started in 1986 at the Agronomic Institute of Paraná, in Pato Branco, in an Oxisol. The treatments are a combination of winter cover crops: black oat, rye, hairy vetch, common vetch, oilseed radish, blue lupine, wheat and fallow, and tillage systems: no tillage (NT) and conventional tillage (CT), in split plot design with three replications. Soil samples were collected in November 2012, in layers 0-5, 5-10 and 10-20 cm. In study 1, the aggregate stability were performed through wet sieving... |

O fósforo (P) orgânico é importante fonte de fosfato para as plantas, tanto em ambientes naturais quanto em solos cultivados. O cultivo de plantas com alta capacidade de reciclagem de P pode aumentar a importância das formas orgânicas na disponibilização de fosfato, especialmente quando o solo não é revolvido O presente estudo objetivou avaliar em um solo muito argiloso sob longo período de cultivo (i) o efeito de diferentes preparos de solo e (ii) o efeito do cultivo de diferentes espécies de plantas de inverno, no teor de carbono e fósforo orgânico do solo. Em 1986 foi estabelecido o experimento com seis tratamentos de inverno (tremoço azul, ervilhaca peluda, aveia preta, nabo forrageiro, trigo e pousio) implantados num Latossolo Vermelho Aluminoférrico... |

Die Nachfrage nach frischem vielfältigem und regionalem Gemüse steigt. Der Großteil des Gemüses wird im Winter entweder importiert oder in geheizten Gewächshäusern angebaut und ist durch einen hohen Energieverbrauch charakterisiert. Im Versuchszentrum Gartenbau der Landwirtschaftskammer NRW in Köln Auweiler wurde zur Erweiterung der Angebotspalette eine Salatmischung aus kältetoleranten Arten untersucht. Die Mischung umfasste Asia-Salate (z. B. Blattsenf, Mizuna, Pak-choi), Sauerampfer, Hirschhornwegerich, Endivie und Speisechrysantheme. Der Anbau im Versuch und in Praxisbetrieben und erwies sich in drei Jahren als unproblematisch. Die Mischung wurde sowohl optisch als auch geschmacklich sehr gut von den Verbrauchern angenommen. Besonders für direkt... |

Die Winterzeit war traditionell die Zeit des Kohlgemüses, da sich dieses gut lagern lässt und Vitamine und Nährstoffe zur Verfügung stellt. Dieser Trend ist jedoch in den letzten Jahren sowohl im ökologischen wie im konventionellen Anbau rückläufig, während die Nachfrage nach frischem Gemüse stetig zunimmt. Im Winterhalbjahr wird dieses entweder importiert oder in beheizten Gewächshäusern produziert. Beide Verfahren sind mit einem hohen Energieverbrauch verbunden, der unter dem Gesichtspunkt der immer weiter steigenden Energiepreise und des ökologischen Fingerabdrucks im ökologischen Landbau als ungünstig zu bezeichnen ist. Ziel des Projekts ist es daher, ein alternatives Frischgemüsesortiment für Produzenten zu entwickeln, mit dem diese ihre... |

Good quality transplants are vital to growers for a number of reasons. Their ability to better tolerate pest, disease and weed problems and their capacity to make better use of newly incorporated green manures (compared to direct drilling) make them all the more so in organic systems. The availability of high quality growing media is essential to producing healthy vigorous plants, but the organic standards restrict the choice of products available and many growers do not feel they have sufficient information to base their choices. OCW, with support from Farming Connect, coordinated a project to assess the certified products and looked at a green waste based product under development to help address this problem. Growers were supplied with samples of... |

In 2009 en 2010 is een praktijkproef uitgevoerd met een alternatief teeltsysteem in de biologische glastuinbouw. Het doel van het alternatieve systeem is het verbeteren van de bodemgezondheid, door verbreding van de vruchtwisseling. Dit moet gebeuren op een manier die economisch rendabe is. In het zogenaamde Köver systeem, worden de plantbedden ondergronds door middel van folie in compartimenten verdeeld. Op de ene helft van het plantbed worden vruchtgroenten geteeld, en op de andere helft van het plantbed kunnen antagonistische gewassen worden geteeld, of kan de gron braak worden gelegd. Paprika blijkt in het systeem veel last te hebben van de antagonistische gewassen, die veel licht wegvangen. Door de rijke grondsoort (locatie Tinte) en hoge temperatuur... |

Bodemkwaliteit is een containerbegrip dat biologische, chemische en fysische componenten omvat. Bodemgezondheid is een nauwer begrip dat beschreven kan worden vanuit een ecosysteem benadering. De begrippen stabiliteit en zelfregulatie, vitaliteit, ecologische veerkracht, organisatiegraad en biodiversiteit worden ten opzichte van elkaar gepositioneerd. Ziektewerendheid is een weer nauwere invulling van het begrip bodemkwaliteit en heeft uitsluitend betrekking op het vermogen van gronden om, ondanks de aanwezigheid van pathogenen, de expressie van de pathogeen in het gewas laag te houden. Negen mechanismen waarop de ziektewerendheid gebaseerd kan zijn worden beschreven. Het feitelijk vaststellen (meten) van ziektewerendheid gebeurt in biotoetsen met... |

In dit tweede deel van dit literatuuronderzoek naar bodemgezondheid in de biologische glastuinbouw is informatie verzameld over 6 belangrijke schimmelpathogenen die in de biologische vruchtgroententeelt van belang zijn: Fusarium, Phomopsis (zwartwortelrot), Pyrenochaeta (kurkwortel), Pythium, Sclerotinia (rattenkeutelziekte) en Verticillium. Behalve aan het herkennen van de ziekte en de ecol ogie van de pathogenen, is specifiek aandacht besteed aan mogelijkheden die biologisch werkende glastuinders hebben om met teeltmaatregelen de ziekten te bestrijden. Afhankelijk van het soort pathogeen zal de keuze op een andere set maatregelen vallen. • Algemene maatregelen zijn het gebruik van compost of andere organische toevoegingen, en de introductie van... |

The effect of two different roofing systems in comparison to the open field (closed tunnel, rain shelter - open field) were investigated in a field experiment during the seasons 2009 to 2011 at the Chamber of Agriculture North-Rhine Westfalia, Station Cologne-Auweiler, Germany. Four shortday varieties ('Clery', 'Darselet', 'Elsanta' and 'Sonata') were used. Considered quality features were yield, behaviour of the fruit during storage, fruit quality such as fruit firmness and sugar- and acid contents. The yield of the shortday strawberries was highest in the tunnel for normal and cold temperatures; under hot conditions the yield was reduced. The rain shelter protects against freezing during cold periods and at high temperatures it reduces heat stress, so... |
