Farmyard manure improves phosphorus use efficiency in weathered P deficient soil [PDF]
, 2019 Crop production is limited by low soil fertility in sub-Saharan Africa (SSA), particularly by P deficiency due to strong fixation by Fe and Al oxyhydroxides.

Waste disposal criteria existing reactor expansion study [PDF]
, 1959 This document discusses waste disposal criteria were established on the basis that the occurrence of river flow rates which were 72 cents of normal would not cause the effects of waste disposal to exceed limits.

Cell Calcification Models and Their Implications for Medicine and Biomaterial Research
Advanced Healthcare Materials, Volume 15, Issue 6, 9 February 2026.Calcification, is the process by which the tissues containing minerals are formed, occurring during normal physiological processes, or in pathological conditions. Here, it is aimed to give a comprehensive overview of the range of cell models available, and the approaches taken by these models, highlighting when and how methodological divergences arise,

GeodermaStruvite (NH4MgPO4·6H2O) is a slow-release phosphorus (P) fertilizer hypothesized to reduce nutrient leaching losses relative to highly water-soluble counterparts such as monoammonium phosphate (MAP). We assessed the leaching fate of P from struvite relative to MAP using soil column experiments for two soils representative of the United States Maize ...

The effect of a shift from macrophyte to phytoplankton dominance on phosphorus forms and burial in the sediments of a shallow hard-water lake [PDF]
, 2019 In shallow lakes, increasing phosphorus (P) loading has often been accompanied by a shift from a clear-water, macrophyte-dominated state to a turbid state featuring phytoplankton dominance.

Agricultural & Environmental LettersAbstractManagement of phosphorus (P) inputs to agroecosystems is often evaluated by phosphorus use efficiency (PUE), but different calculation approaches may yield discrepancies in estimated PUE values. We evaluated PUE (i) indirectly calculated by difference in crop P uptake between a P‐fertilized versus a P‐unfertilized control (PUEdiff) and (ii ...
