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.

ABSTRACT Placement and acidification can improve phosphorus (P) availability from biowastes. However, little is known about how the placement of acidified biowastes affects biotic abiotic processes in soil. Thus, we selected two biowastes: digestate solid fraction (DSF) meat bone meal (MBM). Both were applied their untreated forms. We hypothesised that would affect and, consequently, P dynamics All fertilisers incubated for 12 days to evaluate zone adjacent Assessments included resin‐extractable (resin P) microbial contents δ 18 O values at different distances zone. Microbial respiration was also measured. Acidification significantly increased release DSF MBM. The soil resin content larger even greater (10–12 mm). For MBM, than negative control up 4 mm (50–60 mg kg −1 ). this treatment, relatively (150 6–8 suppressed activity resulted lower rates both MBM DSF.

Abstract Background and aims This study assessed the impact of pH modification pig slurry on dynamics slurry- soil-derived phosphorus (P) after surface application, as a potential alternative to inorganic P fertilizers. Methods Mineral acidification (pH 5), bio-acidification alkalinization 9.5) were strategies used modify using paper industry by-products additive combinations. Maize seedlings grown in rhizoboxes monitor root shoot traits over 23 days. The labile pool sandy loam soil was labeled with 33 distinguish between soil- fertilizer-derived P. Post-harvest analyses included acid phosphatase activity mycorrhizal colonization. Results All (bio)-acidified treatments significantly increased water-extractable by 70% but spent by-product reduced maize growth total uptake. Alkalinized did not affect growth, uptake, or enzymatic activity. Root branching length diminished all acidified treatments, accompanied 59% reduction colonization remaining below 10% across treatments. Conclusion While improved solubility, gains plant uptake biomass limited, likely due inhibitory effects development symbiotic microbial functions, reflecting trade-offs availability plant-soil biological interactions.

The use of anaerobic digestate as a biofertilizer is quite promising in terms soil protection technologies view the reduction environmental risks from mineral fertilizers and positive impact on productivity, improvement their quality restoration humus layer. However, digestion does not ensure complete absence hazards due to certain probability heavy metals, pharmaceutical substances, pathogenic microorganisms entering with biofertilizer. article aimed at determining effective methods processing raw materials digestate, well technological approaches for obtaining geosphere technologies. methodological basis study was meta-analysis based scientific publications within framework systematic approach formation ecological safety fertilizer digestate. It established that type substrate initially affects content nutrients pollutants, but pretreatment materials, thermal chemical, has potential balance ratio NPK remove metals. most relevant choice separation technology. Thus, it essential apply post-treatment its individual fractions. creation granulated organo-mineral production biochar solid fraction are suggested environmentally safe products
