How AI and Digital Technologies Can Enhance Sustainable Livestock Manure Management: An Overview From Treatment to Distribution

Sustainable Development, EarlyView.
ABSTRACT Sustainable livestock manure management sits at the nexus of climate, nutrient circularity and water quality. This review explores how artificial intelligence (AI) and digital platforms are used across four management stages, that is, treatment, storage, valorisation and distribution, and figures out where integration fails to deliver ...

Interactive effect of struvite produced from human urine and emerging contaminants on biological indicators of soil quality

Frontiers in Environmental Science
Struvite produced from human urine is rich in macronutrients. It can be used as a slow-release fertilizer, which helps to promote growth and increase the productivity of agricultural crops. However, struvite may contain pharmaceuticals that can alter the

Optimisation of the preparation of a phosphomagnesium cement based on struvite and K-struvite [PDF]

MATEC Web of Conferences, 2013
Cement is the most widely used material in construction. Its properties are crucial for construction quality. The commonly used cement is Portland cement, which since its discovery in 1812, has continued to be developed in order to improve their properties.

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 ...

BSAVA Petsavers Article: Validation of an ELISA assay for measurement of the metabolite of serotonin, 5‐hydroxyindole acetic acid (5‐HIAA), in canine urine

Journal of Small Animal Practice, EarlyView.
Objectives Serotonin (5‐hydroxytryptophan), implicated in a number of canine diseases, has a very short half‐life in the serum. Urine concentration of its breakdown product 5‐hydroxyindole acetic acid after an 8 hour fast is a more reliable measure of circulating serotonin in humans.

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 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.

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.
