Forest Soil Colloids Enhance Delivery of Phosphorus Into a Diffusive Gradient in Thin Films (DGT) Sink

open access: yesFrontiers in Forests and Global Change, 2021
Phosphorus (P) is preferentially bound to colloids in soil. On the one hand, colloids may facilitate soil P leaching leading to a decrease of plant available P, but on the other hand they can carry P to plant roots, thus supporting the P uptake of plants.

Total carbon content and humic substances quality in selected subtypes of Cambisols

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2009
Cambisols cover an estimated 45% of agricultural soils in the Czech Republic. We aimed our work at stabile forms of organic carbon and humic substances quality in Cambisols under different types of soil management (grassland and arable soil).

Biochar Enhances Nitrous Oxide Reduction in Acidic but Not in Near-Neutral pH Soil

open access: yesSoil Systems, 2019
We quantified nitrous oxide (N2O) fluxes and total denitrification (N2O + N2) in an acidic (Ferralsol) and a near-neutral pH soil (Cambisol) to determine whether biochar’s alkalinization effect could be the mechanism inducing potential reductions ...
