Developing methodologies for measuring the impact of root exudation on soil microbial processes
Plant roots release a diverse cocktail of compounds into soil. These root exudates interact with soil microbes, organic matter and minerals, with important implications for soil functions including soil carbon sequestration, nutri ...

Mitigating N2O emissions from grasslands during extreme weather events using a plant trait-based approach
Intensively managed grasslands are an ecologically and economically important agroecosystem, and are more than half of all agricultural land. Due to nitrogen fertilization, they are also large sources of the potent greenhouse gas  ...

Is it possible to measure soil respiration with a simple hand hold CO2 sensor?
Introduction: Measuring the activity of soil biota can provide important information on the functioning of the soil food web. One way to measure soil biota activity is to determine their respiration activity by monitoring the CO ...

The use of soil amendments to reduce cadmium availability and uptake in cacao.
Cacao production in South America is strongly promoted and linked to important environmental and rural development goals. However, important market-related challenges include new EU food safety regulation setting limits to cadmium ...

Soil bacteriophages in carbon and nutrient cycles
Nematodes and viruses (phages) are important predators of bacteria. Soil is a complex, spatially structured habitat that presents unique challenges for bacteria and their predators. Model experiments have shown that bacteria-feedi ...

Soil bacteriophages in carbon and nutrient cycles, thesis or internship
Soil microorganisms play important roles in carbon cycling, plant nutrition, and greenhouse gas production. Viruses that infect bacteria (phages) are abundant in soil, but their influence on these soil functions is not well known. ...

Impacts of antibiotic residues in manure on soil microorganisms, N-cycling &N2O emissions
Circular agriculture aims to close elemental cycles which increases reliance on animal manure. However, veterinary antibiotics are still commonly used in animal husbandry to treat bacterial infections. As antibiotics are not fully ...

Unlocking the secret of earthworm, root and mycorrhizal fungi interactions
Among the myriad of soil organisms, earthworms and plant roots are pillars for facilitating soil structure formation and improving soil quality. It is well known that roots use old earthworm burrows to expand in the soil, and eart ...

Insects for proteins what about soil fertility?
In a circular economy, diets will be increasingly less meat-based. One way to produce protein-rich products, is to grow insects on organic waste. But what does this mean for soil fertility? Is the manure produced by insects still  ...

From human waste to soil fertility
Current designs for a circularity in agricultural are underdeveloped in terms of their impact on soil fertility. At the same time, nutrients and organic matter from human excreta are under-used. The aim is to bring these two ends  ...
