Soil P Status and Nitrogen Fixation on Organic Dairy Farms in Ontario and Nova Scotia [PDF]

open access: yes, 2010
Legumes are a key source of nitrogen (N) in organic production systems. However, there is evidence that reduced inputs may be leading to deficient soil phosphorus (P) on some organic dairy farms (Roberts et. al. 2008).

In vitro studies on the impact of Apple Cider Vinegar on the growth of struvite urinary crystals

open access: yesNext Materials
Struvite, often linked with some infections, is capable of forming “staghorn calculi” in a short span of time. Thus, the need for cure and prevention of recurrence is crucial. A curative strategy that partially replicates intricate biological systems can

Modelling crystal aggregation and deposition\ud in the catheterised lower urinary tract [PDF]

open access: yes, 2009
Urethral catheters often become encrusted with crystals of magnesium struvite and calcium phosphate. The encrustation can block the catheter, which can cause urine retention in the bladder and reflux into the kidneys.

Bioavailability of phosphorus from composts and struvite in acid soils. [PDF]

open access: yes, 2017
The objective of this study was to assess the type and fractions of phosphorus (P) forms in composts and struvite and how these P forms affect the bioavailability of P in the soil.

Electrochemically recovered struvite matches conventional fertilizers in soil nutrient supply

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract Phosphorus (P) is an essential macronutrient for agriculture, yet global reliance on finite phosphorite reserves raises concerns about long‐term food and nutrient security. Struvite (MgNH4PO4·6H2O), a mineral recovered from municipal wastewater, represents a sustainable and circular source of P, but uncertainty remains regarding its nutrient ...

Vitamin C inhibits crystallization of struvite from artificial urine in the presence of Pseudomonas aeruginosa

open access: yesInternational Brazilian Journal of Urology
Background: Formation of struvite stones is associated with urinary tract infection by urease-producing bacteria. Biogenic crystal growth in natural and synthetic materials is regulated by the action of inhibitors, ranging from small ions, molecules to ...

Ion Exchange for Nutrient Recovery Coupled with Biosolids-Derived Biochar Pretreatment to Remove Micropollutants [PDF]

open access: yes, 2018
Wastewater, especially anaerobic treatment effluent, contains high ammonia nitrogen (NH4-N) and inorganic orthophosphate (PO4-P), which necessitate additional treatment to meet stringent discharge regulations.

Identifying recurrent stone formers with machine learning: A single‐centre observational study

open access: yesBJUI Compass, Volume 7, Issue 3, March 2026.
Abstract Objectives Kidney stones affect 12% of the population over their lifetime. Recurrent kidney stones lead to repeated interventions and excessive healthcare costs. Despite progress in imaging and metabolic evaluations, models to accurately identify patients at high risk are missing.
