    'Staff publications' is the digital repository of Wageningen University & Research

    'Staff publications' contains references to publications authored by Wageningen University staff from 1976 onward.

    Publications authored by the staff of the Research Institutes are available from 1995 onwards.

    Full text documents are added when available. The database is updated daily and currently holds about 240,000 items, of which 72,000 in open access.

Increasing yield is one of the goals in the tropics. Traditional farming is replaced in many cases by agroindustrial production which often leads to environmental pollution due to the marked use of pesticides and fertilizers. In Tabasco, Amashito pepper (Capsicum annum var. glabriusculcum) is cultivated in the traditional way in backyards or cocoa fields with no chemical inputs. The germination of these kind of peppers is difficult to achieve, since wild peppers seeds have a large range of dormancy. Plant-growth-promoting rhizobacteria (PGPRs) are used as inoculants for biofertilization, phytostimulation and biocontrol. Soil fauna has an important function in regulating rhizosphere microbial processes and therefore significantly affects plant growth. Earthworms produce indirect effects through changes in the environment of the roots or via interactions with organisms that affect root growth and production. Our aim was to study the effects of different fresh organic matter, earthworms (P. corethrurus, oligochaeta) and rhizobacteria (A. brasiliensis) on plant growth, and yield production of amashito pepper (Capsicum annuum var. glabriusculum). We established a three factorial outdoors mesocosms experiment. We tested the effects of 3 substrates (dry cocoa husks (C), Panicum sp grass-cocoa husks vermicompost (V), cocoa husks with cow manure (CC) (type of germination substrate, factor 1), the presence (E) and absence of P. corethrurus (WE) (earthworm, factor 2) and the absence (WB) or presence (B) of A. brasiliensis (rizobacteria, factor 3). After 173 days, fruit production was significantly more in plants raised in vermicompost. Vermicompost significantly enhanced the highest weight (23.4g), height (26.7 cm) and production of leaves per plant (20.6 leaves per plant). Further studies are required in order to understand the interactions between vermicompost, plants, earthworms and rhizobacteria.
Een nieuw reactorconcept voor slibreductie met aquatische wormen
Hendrickx, T.L.G. ; Elissen, H.J.H. ; Temmink, B.G. ; Buisman, C.J.N. - \ 2007

De behandeling van afvalwater resulteert in de productie van enorme hoeveelheden zuiveringsslib. In Nederland wordt dit slib voornamelijk verbrand. Een biologische aanpak voor het verminderen van de hoeveelheid slib die moet worden getransporteerd en verwerkt is de predatie door aquatische wormen. Tim Hendrickx, Hellen Elissen, Hardy Temmink en Cees Buisman beschrijven experimenten waarin de toepasbaarheid werd getest van een nieuw reactorconcept voor de reductie van slib met behulp van de aquatische oligochaet Lumbriculus variegatus
Ecologische risico's van bodemverontreinigingen in toemaakdek in de gemeente De Ronde Venen

De gemeente De Ronde Venen ligt in het gebied de Venen in het Groene Hart. De veengronden in dit gebied zijn vanaf de achttiende eeuw regelmatig opgehoogd met stadsafval om hun draagkracht en vruchtbaarheid te verbeteren. De opgebrachte laag wordt toemaakdek genoemd. In dit toemaakdek komen hoge concentraties zware metalen en PAK voor. Om de ecologische risico's van deze verontreinigingen in kaart te brengen is onderzoek gedaan naar de concentraties van de afzonderlijke verontreinigingen en de effecten die deze verontreinigingen hebben op bodemorganismen en daarvan voor hun voedsel afhankelijke vogels en zoogdieren.
