“…Similarly, Kaur and Reddy () described the P solubilizing potential of a Pseudomonas strain along with PR fertilization in a field experiment, suggesting PR as a proliferation substrate for applied bacteria. This assumption is supported from pot experiments ( Li et al, ) and field experiments ( Kaur and Reddy , ) measuring an increased population of P‐solubilizing bacteria in soil when Pseudomonas inoculation was combined with PR or tri‐calcium phosphate. The reported P solubilizing efficacy of bacteria when combined with organic residues ( Thonar et al, ) could not be confirmed from the Compost treatment in our experiment.…”

Recycled phosphorus (P) fertilizers from sewage sludge can contribute to the ongoing effort of closing the P cycle. Five recycled P fertilizers (Struvite SSL, Struvite AirPrex®, P‐RoC®, Pyrolysis coal, and Na‐SSA) were tested for their P availability in a two‐year field experiment with maize. The experiment was conducted on an organic certified research station at soil pH 6.5. Other P fertilizer treatments included: phosphate rock (PR), compost, and an unfertilized control. In addition, the rhizobacteria strain Bacillus sp. Proradix (Proradix®) was applied to test its ability to increase P bioavailability. Each year, shoot DM and P offtake of maize was measured and P use efficiency of the tested fertilizers was calculated. No significant differences in shoot DM were found among fertilized treatments and the unfertilized control in both years of experiment. Fertilization with recycled fertilizers increased P offtake by between 0% (Na‐SSA) and 27.5% (Struvite SSL) compared to the unfertilized control. Rhizobacteria application led to an increase in P offtake of maize from 25.9 to 38.7 kg P ha−1 when combined with PR fertilization in the year of fertilizer application, while no significant effect was found for the recycled fertilizers. Some of the tested recycled fertilizers from urban waste water can be considered as effective fertilizers for their use in organic agriculture.

“…To increase the medicinal values of C. paliurus, optimizing production of the plantation is a research focal point, especially in cultivation management strategies such as chemical fertilization, light quality, and artificial shade [9,32,33]. As a sustainable method for amending the soil, PGPR were applied extensively in crop growing and have been proven to have positive effects on crop output as well as soil properties [12,17,34]. In this study, we focused on not only biomass improvement (leaf) but also the accumulation of BC in C. paliurus leaves by the addition of PGPR to the growing medium.…”

“…However, after long-term chemical fertilization, soil degradation and pollution have been getting worse. At the same time, limited nutrients in the soil are sustainably exploitable for plant uptake due to N-leaching, ammonia volatilization, and P-immobilization [11,12]. Recently, owing to advances in the understanding of microorganism-plant interactions, researchers' attention has been attracted by increasing applications of biological and natural fertilizers, because of their outstanding performance in crop growth and smaller ecological footprint compared with chemical fertilizers.…”

Research Highlights: We firstly interpreted nutritional mechanisms involved in growth regulation and phytochemical accumulation in Cyclocarya paliurus (Batal.) Iljinskaja under three inoculant types, and selected bacterial inoculations for multiple purposes of C. paliurus plantation. Co-inoculation with phosphate-solubilizing bacteria (PSB) and N2-fixing bacteria (NFB) performed better in growth promotion and nutrient uptake than single bacterial inoculation. Background and Objectives: C. paliurus is a well-known medicinal plant as it accumulates bioactive compounds (BC) such as flavonoids, triterpenoids, and polysaccharides, in its leaves. However, the effects of plant growth-promoting rhizobacteria (PGPR) on the growth and BC yields in C. paliurus are not known. To fill this gap, the effects of different inoculants should be examined. Materials and Methods: A pot experiment was conducted and two-year-old C. paliurus seedlings were inoculated with three inoculant types (PSB, NFB, PSB + NFB). After four rounds of inoculation, the growth characteristics and concentrations of flavonoids, triterpenoids, and polysaccharides, as well as the nutrients in soil and leaves, were measured. Results: The inoculations resulted in the elevation of soil available nutrients, with improvements in plant growth, BC yield, and N and P uptake in leaves. However, the changes in BC yields were mainly a result of elevated leaf biomass rather than BC concentrations, and leaf biomass was regulated by C:N:P stoichiometry. Co-inoculation with PSB and NFB was applicable for leaf production, while inocula related to NFB resulted in higher BC yields than PSB and control. Conclusions: Our results implied that bacterial inoculants improved plant growth and BC yield by altering the nutrients in soil and leaves, while three inoculant types showed a different pattern in which co-inoculation with four strains presented a greater performance than single bacterial addition.

“…Fertilizing with mineral fertilizer did not give such effects. These studies suggest that the use of phosphate biopreparations together with calcium phosphate fertilization was more economical due to the reduction of fertilizer consumption costs and an increase in the yield [8].…”

“…Nawożenie nawozem mineralnym bez wzbogacenia nie dało takich efektów. Przeprowadzone badania sugerują, że stosowanie biopreparatów fosforowych wraz z nawożeniem fosforanem wapnia było bardziej ekonomiczne ze względu na zmniejszenie kosztów zużycia nawozu i zwiększenie wielkości plonu [8].…”
