    Groenekennis - Informatie voor professionals in voedsel en groen

    Groenekennis bevat artikelen uit vaktijdschriften, rapporten, video’s, presentaties, posters en websites op het gebied van landbouw, visserij, groene ruimte en voeding. Groenekennis wordt dagelijks bijgewerkt en bevat ongeveer 500.000 bronnen.

    Groenekennis is de globale view over diverse deelbestanden. Groenekennis is gevuld met alle informatie uit Groen Kennisnet, de Hydrotheek, Tuinpad, IB archief, ARTIK, bioKennis, Kennisbank Plantaardige bronnen, Kennisbank Zeldzame landbouwhuisdieren en afgesloten documentatiebestanden zoals Land Bodem Water en Consumenten- en huishoudstudies.

    Groen Kennisnet is een zeer belangrijk onderdeel van Groenekennis. De doelstelling van Groen Kennisnet is kennis delen op het gebied van Voedsel en Groen te bevorderen en te faciliteren voor een breed publiek.

    Bronnen in Groenekennis kunnen direct opgevraagd worden via een geavanceerde zoekmachine met een 'google-achtige' interface. Met filters kan ingezoomd worden op diverse aspecten, zoals Trefwoord, Collectie, Jaar en Auteur. Bovendien biedt Groenekennis gebruikers de mogelijkheid om via de E-mail geattendeerd te worden op aanvullingen in specifieke vakgebieden.
    De Tijdschriftenlijst biedt een overzicht van tijdschriften waaruit de artikelen voor Groenekennis worden geselecteerd. Door te klikken op een titel krijgt u alle artikelen uit dat tijdschrift in de Groenekennis database getoond.
    Zoeken op kaart biedt een geografische ingang op de beschikbare publicaties over de binnen dit bestand onderscheiden gebieden.

    Groenekennis is onderdeel van het bibliotheeksysteem van WUR. Praktijkgerichte publicaties en rapporten van WUR komen daardoor automatisch beschikbaar. Daarnaast wordt de database doorlopend gevuld met voor het groen onderwijs bruikbare bronnen en artikelen, video’s en websites. Het percentage online is de laatste jaren gegroeid tot tweederde van de totale aanwas per jaar. Dit percentage groeit nog steeds.

Effects of stockpiled and composted manures on germination and initial growth of cress (Lepidium sativum) \ Biological agriculture and horticulture : an international journal [Artikel]
Pare, T. \ Gregorich, E.G. \ Dinel, H. \ 1997
In cold areas, winter may delay the composting process and biomaturity when composting is carried out outdoors. Immature compost may lead to seed germination inhibition and plant injuries. In Canada, experiments were performed in which water extracts ...

Mineralization of composted 15N - labelled farmyard manure during soil incubations \ Biological agriculture and horticulture : an international journal [Artikel]
Cheneby, D. \ 1994
Fresh farmyard manure was labelled with 15N during composting in a bench-scale reactor to determine the C and N mineralization in two selected silty Belgian soils which had been cultivated under organic farming practices for many years

Determination of compost biomaturity. 3. Evaluation of a colorimetric test by 13C-NMR spectroscopy and Pyrolysis-Field Ionization Mass Spectrometry \ Biological agriculture and horticulture : an international journal [Artikel]
Schnitzer, M. \ 1993
In part 2 of this series on biomaturity of compost it was concluded that optical density at 665 nm might form the basis of a suitable biomaturity test. In this article the 665 nm colorimetric test is evaluated by characterizing the carbon and individ ...

Determination of compost biomaturity. II. Optical density of water extracts of composts as a reflection of their maturity \ Biological agriculture and horticulture : an international journal [Artikel]
Mathur, S.P. \ 1993
The purpose of this study was to determine whether the optical density of various attributes of water extracts of composts reflects biomaturity and can be the basis of simple reliable tests for determining the biomaturity of compost. From four types ...

Determination of compost biomaturity. I. Literature review \ Biological agriculture and horticulture : an international journal [Artikel]
Mathur, S.P. \ 1993
More than twenty-five tests that have been proposed for testing the biomaturity of composts are reviewed. According to this evaluation an experimental approach for evolving a single, facile and reliable test is discussed. In subsequent articles resul ...
