Development of guidelines for soil function restoration at abandoned small-scale gold mining sites in Suriname
Artisanal and small-scale gold mining (ASGM) is a significant source of income in the inland areas of Suriname, which are located on the Guiana Shield, a region known for its abundant gold deposits. Unfortunately, ASGM activities  ...

Eliminating the competition: can Fe uptake by plants be improved by applying soil additives that bind elements that interfere with plant Fe acquisition strategies?
Iron (Fe) is an essential micronutrient to plants that is abundantly present in almost all soils. However, in alkaline and calcareous soils with a circumneutral pH (7 – 8.5), covering approximately one third of the earth’s land su ...

Towards a mechanistic basis for the DTPA/EDTA-extraction for establishing the micronutrient availability in soils
Poor availability of micronutrients like Fe, Zn, Cu and Mn can limit primary productivity and dramatically reduce crop yields. Micronutrient deficiency in crops is particularly (but not exclusively) observed on alkaline and calcar ...

High affinity adsorption to Fe-oxide nano particles. Does it occur and is sulfate involved?
Sulfate is an anion omnipresent in natural systems, where it is bound by metal (hydr)oxides. Ferrihydrite is the most reactive nano-Fe-oxide material in nature. Therefore, its ion adsorption properties are crucial for understandin ...

Long-term chemical losses of phosphorus fertilizer
Goal: Improve our understanding of long-term chemical losses of P fertilizer Background and why: Phosphate is one of the most important nutrients for crop growth. However, phosphate reacts strongly with various soil particles w ...

Help us to improve efficient P fertilization!
Goal: Acquire a better understanding of the effect of soil physical properties on phosphorus uptake. Why: Assessing soil P availability for crop growth is currently purely based upon the chemical P availability of soil. This i ...

Long-term trends in leachate contaminant concentrations of bioreactor landfills
Landfills pose a large threat to the human health & environment (HHE), both through gaseous emissions and through the release of contaminant-rich leachate to the underlying soil. Traditionally landfills are sealed to restrict thes ...

Effect of pH on organic matter concentrations and humic substance fractions
Nutrient and contaminant availability in soil systems is for a large part determined by their adsorption to reactive surfaces, i.e. clay, metal (hydr)oxides, and organic matter (OM). The “reactive” OM fraction is commonly oper ...

Selective removal of Cd from agricultural soils using chelating ligands
Contamination of agricultural soils with heavy metals is a global concern that threatens food safety and public health, as well as the livelihood of farmers. Heavy metal uptake from soil by crop plants and subsequent translocation ...

The effect of naturally occurring ligands on the weathering rate of stone meal
The application of stone meal (rock dust) in natural and agroecosystems has recently received a lot of attention for its great potential to concurrently improve soil quality and sequester carbon. For instance, it’s currently being ...
