Busy beavers capture carbon
Environmental scientists have proposed drawing carbon out of the air and burying it to reduce greenhouse gasses and the impact of climate change. Maybe we can take some tips from nature’s own eco-engineers – beavers – which  ...

Disentangling the role of earthworms in cycling soil phosphorus using an isotopic approach
Earthworms play a key role in the soil nutrient cycling and thus participate in maintaining soil fertility. It is widely recognized that the phosphorus availability is higher in earthworm affected soil compared with the surroundin ...

Effect of viruses on soil biogeochemical functions
Soil microorganisms play key roles in carbon cycling, plant nutrition, and greenhouse gas production (N2O and CH4). Viruses, by increasing microbial death rates, could strongly affect these processes. Viruses that infect bacteria  ...

Effects of fertilizer amendments and earthworm abundance on N2O and CO2 emissions from peat soils
Peat meadow soils in The Netherlands are of interest to different parties for divergent reasons. Livestock farmers benefit from relatively low groundwater tables, which make the soil stable enough grazing and equipment access. On  ...

How do moisture conditions affect the biological processes involved in peat decomposition?
It is well known that drainage of peat soils leads to decomposition of the organic matter in these carbon rich soils. This problem is increasingly being recognized recently, as is apparent from the goal in the Dutch climate agreem ...

Biological soil quality indicators for agricultural management and environmental impact
Soil quality indicators are important tools for assessing the state of agricultural soils as affected by management practices (e.g. tillage, farming system) or environmental impact (e.g. climate change ). The knowledge generated b ...

Is there a need to apply organic fertilizers to agricultural soils?
: Soil organic matter is highly relevant to multiple soil processes and functions. How much needs to be applied from which quality to supply specific functions, however, is not clear. A long term field experiment with plots that h ...

Moisture and temperature effects on peat soil respiration
Peat soils play an important role in the global carbon cycle, through their ability to sequester a large stock of carbon. In the Netherlands, about 60% of peat soils are used as grasslands. Intensive drainage of these peat meadows ...

Climate resilience in agroforestry systems.
Agroforestry is increasingly recognised as a potential mitigation and adaptation strategy against climate change. Agroforestry is often argued to increase soil carbon, improve nutrient cycling and promote soil biodiversity. Howeve ...
