Phosphorus removal in passive treatment technologies for tertiary wastewater treatment [PDF]

, 2014
The treatment of phosphorus at small sewage works requires alternative approaches to the traditional chemical precipitation and biological removal pathways, as such approaches do not align well to the requirements at such a scale in relation to the use

Effect of liming on the fate of applied superphosphate phosphorus in some mineral soils

Agricultural and Food Science, 1967
The effect of liming on the distribution of superphosphate phosphorus in various fractions of soil phosphorus was studied. Samples of four mineral soils (pH 3.9 to 5.1) were incubated at room temperature for eight months with 0, 0.5, or 1.0 per cent ...

Phosphorus Dynamics in Managed and Natural Soils: SEM-PLS Analysis of Vaccinium, Forest, and Grassland Ecosystems

Plants
Phosphorus (P) availability in soils is often constrained by its accumulation in non-labile phosphorus (NLP) forms, limiting its accessibility to plants.
