K-struvite, the main hydrate of magnesium potassium phosphate (MKP) cements, dehydrates at ~50 °C, thus elevated temperatures service conditions could affect cement properties and durability. In this study, hydration MKP without with wollastonite were investigated 20 50 °C. hydrated pure K-struvite decomposes progressively over time to MgKPO4·H2O which leads a strong reduction solid volume seve...

The form and opener configuration used to apply phosphorus fertilizer can influence its effectiveness crop response. A growth chamber study was conducted examine the response of (canola, wheat, pea grown in rotation) soil P (monoammonium phosphate struvite), spread (narrow versus wide), rate treatments 0, 20, 40, 60 kg P2O5 ha−1 added canola (B. napus) seed-row, followed by wheat without fertil...

Environmental legislation on waste management coupled with the potential for nutrient recovery are key factors encouraging use of advanced treatment technologies to manage biosolids waste. In this context, phosphorus from sewage sludge treated by a wet oxidation (WO) process was carried out in work. High organic matter (up 85% COD) and total solids content 75%) removal values were achieved WO a...

Abstract Purpose Although struvite (MgNH 4 PO ·6H 2 O) is mostly considered to be a novel phosphorus (P) fertiliser, it does contain significant amount of nitrogen (N). Yet, relatively little known about the soil N dynamics in struvite-amended soils. Here, we focus on how application impacts emissions greenhouse gas nitrous oxide (N O), relation P status. Methods We conducted 54-day pot experim...

Urban agriculture, while being a promising solution to increase food sovereignty in cities, can lead an unprecedented discharge of nutrient and fertilizer-related emissions into the urban environment. Especially relevant are nitrogen (N) phosphorus (P), due their contribution marine freshwater eutrophication. Therefore, alternative methods fertilization need be put practice avoid such impacts s...

Introduction: Urolithiasis is rare in developed countries. Staghorn calculi are a type of upper urinary tract stone that involves the renal pelvis and extends into at least two calyces. Although all types of urinary stones can potentially form staghorn calculi, approximately 75% are composed of a struvite matrix and are generally associated with urinary tract infection caused by urea -splitting...
