Roles of phosphate-solubilizing bacteria in mediating soil legacy phosphorus availability

The Use of Two Locally Sourced Bio-Inocula to Improve Nitrogen and Phosphorus Cycling in Soils and Increase Macro and Micronutrient Nutrient Concentration in Edamame (Glycine max. L.) and Pumpkin (Cucurbita maxima)

“…in solubilizing soil P and therefore making the P more plant-available [69][70][71]. Additionally, the observed significant decrease in TKP in this study is suggestive of P mineralization and solubilization by PSBs (Figure 4a), and may have resulted in two P pools, primarily OP, which, upon incorporation into microbial biomass, can act as a potential P source for the next crop rotation [72], and, secondly, M1 P, a significant source of plant nutrients.…”

“…In pumpkin, summer 2018, with M1 P in 4th-week soil, LEM was about 38% greater than the Control (Figure 4b) (p < 0.05). The addition of PSBs (predominately Pseudomonadaceae, Bacillaceae, and Lactobacillaceae; Table 3) through both liquid inoculum (applied in the summer of 2017) and inoculated compost in conjunction with the liquid inoculum (applied in the summer of 2018) played key roles in solubilizing soil P and therefore making the P more plant-available [69][70][71]. Additionally, the observed significant decrease in TKP in this study is suggestive of P mineralization and solubilization by PSBs (Figure 4a), and may have resulted in two P pools, primarily OP, which, upon incorporation into microbial biomass, can act as a potential P source for the next crop rotation [72], and, secondly, M1 P, a significant source of plant nutrients.…”

Aprimorando a Gestão De Nutrientes Do Solo Com Microrganismos Solubilizadores De Fosfato

“…Diversos microrganismos, tais como bactérias, fungos, cianobactérias e micorrizas, demonstram a capacidade de solubilizar fosfato no solo, por meio de fontes de carbono, como a glicose, através de processos de respiração oxidativa ou fermentação de compostos orgânicos, e em troca, empregam mecanismos que favorecem o crescimento vegetal (SHARMA et al, 2013;CHEN et al, 2016;ELHAISSOUFI et al, 2022). Esses mecanismos incluem a liberação de compostos complexantes ou dissolventes de minerais, como ânions de ácidos orgânicos, sideróforos, prótons, íons hidroxila e CO2 e a liberação de enzimas extracelulares para a mineralização bioquímica de P (GUPTA et al, 2022;LI et al, 2023).…”

Effects of temperature-related changes on charred bone in soil: From P release to microbial community

“…It is a critical element in nucleic acids, enzymes, phosphoproteins, phospholipids, etc. ( Tamburini et al., 2012 ; Kamerlin et al., 2013 ; Li et al., 2023a ). However, it has been predicted that current global reserves of phosphate rocks may be depleted within 50–100 years due to the increasing demands and dwindling stocks ( Cordell et al., 2009 ; Gilbert, 2009 ).…”
