Recovering nutrients from urine – A golden opportunity for sustainable fertiliser production
PLANTS, PEOPLE, PLANET, Volume 8, Issue 3, Page 747-753, May 2026.Agricultural industrialisation has led to levels of nutrients in the environment that are well above safe operating limits, yet fertiliser use is necessary to feed a growing population. The recovery of nutrients from human urine in large, developed cities may offset some of the ecological and economic impacts associated with fertiliser production, as ...

Investigating Conductivity to Predict Magnesium Addition Requirements for Struvite Precipitation in Swine Manure Slurries [PDF]
, 2009 The goal of this project was to develop a system that identified magnesium demand for struvite formation by monitoring conductivity changes during continuous injection of magnesium chloride in several swine manure slurries. The conductivity of six manure

Water and Environment Journal, Volume 40, Issue 2, Page 290-300, May 2026.This study investigates the impact of calcium on the performance of a large‐scale internal circulation (IC) reactor treating calcium‐rich dairy wastewater. Excessive calcium concentrations (400‐600 mg L−1) resulted in calcification of the anaerobic sludge, reactor walls, and pipes, suggesting a 17% and 25% reduction in biogas and methane production ...

Management of struvite uroliths in dogs [PDF]
British Journal of Nutrition, 2011 Urolithiasis is a common clinical problem in dogs. Struvite and calcium oxalate are the predominant mineral types in dog urolithiasis. The aim of the present study was to compare the effect of two commercial dry foods formulated for the management of struvite urolithiasis with different anion–cation balance on urinary pH.

Influence of nutrition on feline calcium oxalate urolithiasis with emphasis on endogenous oxalate synthesis [PDF]
, 2011 The prevalence of calcium oxalate (CaOx) uroliths detected in cats with lower urinary tract disease has shown a sharp increase over the last decades with a concomitant reciprocal decrease in the occurrence of struvite (magnesium ammonium phosphate ...

Journal of Plant Nutrition and Soil Science, Volume 189, Issue 2, Page 276-286, April 2026.In a short‐term pot experiment, three legume‐based crop rotations are being tested for their effects on the P cycle and P use efficiency compared to maize monoculture. Legume‐based crop rotations stimulate the P cycle by increasing acid phosphatase activity and carboxylate exudation.
