PhD Soil Biology / Soil Fertility


Wageningen University, Department of Soil Quality


PhD Soil Biology / Soil Fertility
Wageningen, (Gelderland), 38 hours per week
Wageningen University, Department of Soil Quality

Job description

________________________________

In a concerted action, two PhD students and a post-doc will study how
plants, in particular genetically modified (GM) plants, can change their
own soil ecosystem. Plants can have profound effects on soil organisms,
because the great majority of carbon input in soils originates from
living plants (root exudates) and from dead plant material. It needs to
be tested if GM plants have such influence too, and if yes, if this
influence is different from non-GM plants. Crops with e.g. GM-increased
resistance against pathogens and herbivores, can have side-effects on
beneficial rhizosphere-inhabiting organisms; residues of crops with
GM-altered tissue composition may have different decomposition rates,
and thereby affect soil decomposer communities. Given the importance of
the soil community for soil carbon and nitrogen cycles, effects of GM
plants on non-target soil organisms and processes have to be evaluated
properly prior to their admission. The research program aims to deliver
a tool for risk assessment of GM plants based on soil nematodes that
will enable evaluation of risks of these plants for soil fertility
functions.

The major research question for the PhD Soil Quality is: To what extent
do plants affect soil fertility functions, and is this affect mirrored
by nematode community shifts that can be measured easily? Initially, we
will use non-GM Brassica species because they produce glucosinolates
with a broad spectrum effect on soil life. Varieties that produce more
or less glucosinolates are used to test effects on nematodes and C and N
dynamics in soil. Nematodes are a species-rich soil fauna group with
great bioindicator potential. Changes in nematode community structure
will be experimentally linked to soil fertility functions such as
organic matter decomposition and nitrification. Results will be used to
develop an Ecological Risk Assessment guidance for GM crops.
