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.

Legumes have a high demand for phosphorus (P) due to energetically costly biological nitrogen fixation, but they also effective physiological and morphological strategies P mobilization. To evaluate the inter- intraspecific efficiency of small-grain legumes supplied with different recycling fertilisers, eight accessions each alfalfa (Medicago sativa L.) red clover (Trifolium pratense were cultivated in two pot experiments under greenhouse conditions until flowering stage. substantiate results, some used both experiments. Five treatments (no P, triple-superphosphate (TSP), sewage sludge ash (SSA), biowaste compost (compost), struvite) considered sources. In addition plant uptake, soil pools analysed detail. Red showed higher yields nutrient uptakes compared alfalfa, effects marginal. The resulted only partly an increase yield, despite low content soil. While struvite application clearly enhanced uptake plants experiments, SSA had no effect control. same treatment occurs bio-available contents, which on average 72.6 mg kg−1 after 44.3 addition. Struvite as source was especially when applied clover. Our study aligns previous field results underscores potential mobilization without pronounced or differences. is suitable fertiliser, not recommended.

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.

The pollutant input and the risk of contamination by long-term application recycled P fertilizers (RPFs) in European agricultural soils were estimated a mass balance approach. Calculations based on literature data carried out for potentially toxic elements (PTEs) Cd, Cr, Cu, Ni, Pb, Zn persistent organic pollutants (POPs) PCBs, PAHs polychlorinated dibenzo-dioxins -furans. PTE accumulation estimation during 200 years fertilizer application, equivalent to 11 kg ha−1 year−1, mean export via harvested products stockless farms, regarded soil background concentrations proposed threshold concentrations. For PTEs, inputs atmospheric deposition liming, output processes leaching crop harvest. effect varying site conditions was assessed considering two precipitation excess (F) values pH values. POPs, half-life time considered. low most RPFs. analysed POPs no found. highest found all PTEs at 7 F = 0.1 m lowest 5 0.3 year−1. A high concentration resulted flow per unit P. Composts had due contents. Struvite, meat bone meal, digestate catering waste, ash biosolids would be better suited as fertilizers. use should regulated their pollutant-to-nutrient ratio.

Abstract Limited nutrient availability is one of the major challenges in organic farming. Little known about budgets farms, underlying factors or effects on soil fertility. We therefore assessed farm gate for nitrogen (N), phosphorus (P), potassium (K), magnesium (Mg) and sulfur (S) 20 farms Germany analyzed their nutri-ent status. In average, showed a surplus N (19 kg ha−1), K (5 S (12 Mg (7 deficit P (−3 ha−1). There was, however, high variability between (e.g. standard deviation up to ± 36 which was mainly explained by different degrees reliance biological fixation (BNF) as source. When obtained more than 60% input through BNF, they had deficits (mean −8 ha−1) −18 Nutrient status most soils within ad-vised corridor, but P, Mg, 10–15% fields were lower 45–63% higher advised.
