A better understanding of the effectiveness of placed phosphorus fertilisation with struvite for silage maize: A pot experiment

Geoderma
Struvite is emerging as a circular, slow-release phosphorus (P) fertiliser. However, its effectiveness for crops and its impact on soil P tests still remain largely unclear.

Effect of Two Therapeutic Renal Diets on Hormonal and Regulatory Pathways Affecting Calcium Homeostasis in Cats With Early‐Stage Chronic Kidney Disease

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Chronic kidney disease (CKD) is a known risk factor for hypercalcemia in cats. Phosphate‐restricted diets have also been implicated in causing hypercalcemia, in part because phosphate restriction increases the Ca:P ratio. The primary objective of this study was to evaluate the impact of two different therapeutic renal foods on ionized (iCa ...

Recovery of phosphorus from stored urine using continuous flow reactor in decentralised level operations

Blue-Green Systems, 2020
Past studies have shown that phosphate recovery in the form of struvite is relatively a simple process, which can be achieved by adding a magnesium source in stored urine.

Women in space: A review of known physiological adaptations and health perspectives

Experimental Physiology, EarlyView.
Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

Potential Influences of Bacterial Cell Surfaces and Nano-Sized Cell Fragments on Struvite Biomineralization

Crystals, 2020
Struvite (MgNH4PO4·6H2O) calculi are formed as a result of urinary tract infections by Proteus mirabilis and other urease-producing bacteria. During struvite formation, the bacteria grow as biofilms, and thus crystals are formed in close association with

Quantitative Susceptibility Mapping of Kidney Stones: An Ex Vivo MRI Phantom Study

Magnetic Resonance in Medicine, Volume 96, Issue 4, Page 1846-1859, October 2026.
ABSTRACT Purpose To visualize and characterize the five most common kidney stone types based on their magnetic susceptibilities in MRI using QSM. Methods Three water‐based agar phantoms were constructed, containing a total of 53 ex vivo kidney stones of varying types and sizes.

Effect of Calcium Additive on the Crystallization of Struvite

MATEC Web of Conferences, 2016
Crystallization of struvite [MgNH4PO4.6H2O] may lead to the deposition of scale which may create significant problems in the process pipes, pumps and other industrial equipment.

Using P‐Mobilization Traits in Modern Maize Varieties for Optimizing the P Fertiliser Use Efficiency of Struvite Under P Limitation: First Evidence From a Pot and Field Trial

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 3, September 2026.
ABSTRACT Introduction Current recycling measures for closing the phosphorus (P) cycle are limited by the lower fertiliser use efficiencies of recycled products. Increasing P use efficiency (PUE) through maize genotype selection and management may offer a sustainable solution, but the potential of variety choice and its interaction with placed ...
