Summary
This 2024 laboratory investigation examined the fate and bioavailability of inorganic phosphorus in manufactured soils, a subject of growing importance as engineered substrates are increasingly used in horticulture, remediation, and constructed ecosystems. The authors characterised phosphorus sorption, desorption, and mobility mechanisms to inform better design and management of such soils. The findings contribute to understanding how phosphorus availability can be optimised or constrained in non-natural soil environments.
UK applicability
Results are directly relevant to UK horticulture and urban greening practices, where manufactured soils are widely used in container production, living walls, and remediated brownfield sites. Improved understanding of phosphorus availability in these substrates could support more efficient nutrient management and reduce environmental losses in high-input cultivation systems.
Key measures
Inorganic phosphorus speciation, adsorption–desorption dynamics, soil pore-water phosphorus concentration, phosphorus mobility indices, and bioavailability fractions (as suggested by journal scope and topic)
Outcomes reported
The study examined how inorganic phosphorus behaves in terms of its availability to plants and its mobility within manufactured soil substrates. As suggested by the title, the research characterised phosphorus fractionation, retention, and potential leaching pathways in engineered soil.
