Recovering human-derived nutrients from sanitation systems can offset inorganic fertilizer use and improve access to agricultural in resource-limited settings, but the agronomic value of recovered products depends upon product chemistry soil context. Products may exacerbate already-compromised conditions, offer benefits beyond nutrients, or have reduced efficacy depending on characteristics. Using global spatial modeling, we evaluate suitability seven (wastewater, sludge, compost, urine, ammonium sulfate, struvite, potassium struvite) integrate this information with local recovery potential each that will need be installed achieve universal coverage (referred here as "newly-installed sanitation"). If reuse are colocated, quantity nutrient was variable across countries. For example, alkaline (e.g., particularly beneficial when applied acidic soils Uganda potentially detrimental southwestern United States.

ABSTRACT Background Placement and acidification pretreatments are strategies to enhance the phosphorus (P) fertilizer value of biowastes. However, their impact on commercial yield horticultural crops effects contents undesirable elements in edible product not well known. Aims The main objective this study was assess how placement biowastes affect nutritional quality vegetables. Methods To investigate this, we selected two byproducts from agroindustries, meat bone meal (MBM) digestate solid fraction (DSF), conducted a pot experiment with peas onions growing 10‐L pots. Four treatments were assessed for each biowaste: untreated mixed (UM), placed (UP), acidified (AM), (AP). Results Acidification increased water‐soluble P both byprodutcs over 70% total P. For DSF, AP treatment yielded 100% more than UM, exceeding triple superphosphate. MBM, no significant differences found among AM, treatments, UP yielding even less negative control, indicating toxicity effect, probably ammonium that reduced plant growth. Although may have solubility elements, it reflected composition, as higher contributed yields, diluting element content. Conclusions Therefore, DSF shows promise improving value, adverse content onion bulbs pea grains.

Soil phosphorus (P) cycling in agroecosystems is highly complex, with many chemical, physical, and biological processes affecting the availability of P to plants. Traditionally, fertilizer recommendations have been made using an insurance‐based approach, which has resulted accumulation intensively managed agricultural soils worldwide contributed widespread water quality issue eutrophication. To mitigate further environmental degradation because future supplies are threatened due finite phosphate rock resources associated geopolitical issues, there immediate need increase use efficiency (PUE) agroecosystems. Through cultivar selection improved cropping system design, contemporary research suggests that sufficient crop yields could be maintained at reduced soil test (STP) concentrations. In addition, more efficient field scale can achieved through agroecosystem management increases organic matter mineralization optimizes arbuscular mycorrhizal fungi (AMF) symbioses. This review paper provides a perspective on how agriculture potential utilize plant microbial traits improve PUE accordingly, maintain lower STP It also links tighten cycle regional scale, including discussion recovery recycling technologies, particular focus struvite as recycled fertilizer. Guidance directions for provided. Core Ideas There urgent Crop than recommended Both quantity influence availability. Further ability supply crops needed. Struvite fill important niche recycling.

Use of nutrients recycled from societal waste streams in agriculture is part the circular economy, and line with organic farming principles. Nevertheless, diverse contaminants create doubts among farmers about potential risks for soil health. Here, we gather current knowledge on contaminant levels nutrient sources, discuss associated risks. For potentially toxic elements (PTEs), input zinc (Zn) copper (Cu) mineral feed supplements remains concern, while concentrations PTEs many have decreased substantially Europe. The same applies to contaminants, although new chemical groups such as flame retardants are emerging concern globally contamination differ strongly.
