“…Intercropping seemed to lower P nutrition due to lower P availability. Paul et al (2018) compared SOC, P fractions and P cycling enzymes over 5 different land-uses including an uncultivated land, an apple orchard, an oak forest, wheat-maize rotation farmland and organic farming system in India. They showed that enzyme activities were very sensitive to land-use change.…”

“…Similarly, the phoD -harboring bacterial community correlated significantly with soil property in several studies (Chen et al, 2017; Luo et al, 2017). Paul et al (2018) reported that land use patterns influenced the soil microbial community structure, mainly by changing soil properties. Sun et al (2016) also found that soil parent material determined soil bacterial community structure, where the variation of soil properties was the main reason.…”

“…That may be because the larger variation in soil properties masks the role of land use pattern, soil parent material, and sampling location. This phenomenon should be particularly evident in acidic soils, because soil characteristics including low pH, Al toxicity, P, and N deficiency are more sensitive to soil conditional changes (Guo et al, 2010; Paul et al, 2018). For example, Al toxicity as an important limiting factor in acidic soil has been reported to severely decrease soil microbial abundance and affect microbial diversity (Kunito et al, 2016).…”

Phosphorus (P) deficiency is an important factor that limits the agricultural production potential in acidic soils. The bacterial phoC gene encodes non-specific acid phosphatase (ACP), which participates in the mineralization of soil organic P and is therefore important for the improvement of soil P availability. However, the function and community population of phoC-harboring bacteria and their driving factors in acidic soil remain largely unknown. For this study, 51 soil samples and 207 plant samples were collected from four locations in the acidic soil region of southern China. Quantitative PCR and high-throughput sequencing were employed to analyze abundance and community composition of phoC-harboring bacteria. The results showed that soil P availability was the important nutrient element limiting the growth of both plants and soil bacteria. Soil ACP activity was clearly higher than alkaline phosphatase, indicating the important effect of phoC-harboring bacteria in acidic soils. ACP activity and phoC gene abundance showed a significant positive correlation, and both were closely related to soil available P, total carbon, and total nitrogen. The dominant genera of phoC-harboring bacteria involved Cupriavidus, Stenotrophomonas, and Xanthomonas. Compared to land-use pattern, sampling location, and soil parent material, soil property played a more important role in affecting phoC-harboring bacterial community structure, where N-related variables including soil NO3- -N, NH4+ -N, and C/N ratio appeared to be the main factors. These findings suggest that phoC-harboring bacteria should provide an important contribution to soil P availability in acidic soil, and its function and community composition were strongly associated with soil nutrients.

“…Different authors have reported both genera have the capacity to solubilize inorganic phosphorus (tricalcium phosphate and PR), mineralize organic phosphorus (phosphatase activity), produce substances promoters of vegetable growth and substances for biological control of rhizosphere phytopathogens [ 16 , 17 , 52 , 55 , 56 ]. When co-cultured they can increase and complement their potential as a bio-inoculant, in such manner the plant can benefit during different stages of development, such as seed germination, seedling propagation, seedling in seedbeds and cultivation in plots.…”

Different genus of bacteria has been reported with the capacity to solubilize phosphorus from phosphate rock (PR). Pseudomonas sp., (A18) and Serratia sp., (C7) isolated from soils at the “ Departamento de Boyacá ” Colombia, where Allium cepa is cultivated. Bacteria were cultured in MT11B media and evaluated as a bio-fertilizer for A. cepa germination and growth during two months at greenhouse scale. Pseudomonas sp., and Serratia sp., cultured at 30 °C, 48 h in SMRS1 agar modified with PR, (as an inorganic source of phosphorus), presented a phosphate solubilization index (SI) of 2.1 ± 0.2 and 2.0 ± 0.3 mm, respectively. During interaction assays no inhibition halos were observed, demonstrating there was no antagonism between them. In MT11B media growth curve (12 h) demonstrated that co-culture can grow in the presence of PR and glucose concentrations 7.5-fold, lower than in SMRS1 media and brewer's yeast hydrolysate; producing phosphatase enzymes with a volumetric activity of 1.3 ± 0.03 PU at 6 h of culture and 0.8 ± 0.04 PU at 12 h. Moreover, co-culture released soluble phosphorus at a rate of 58.1 ± 0.28 mg L −1 at 8 h and 88.1 ± 0.32 mg L −1 at 12 h. After five days of evaluation it was observed that germination percentage was greater than 90 % of total evaluated seeds, when placing them in contact with the co-culture in a concentration of 1 × 10 8 CFU mL −1 . Furthermore, it was demonstrated that co-culture application (10 mL per experimental unit to complete 160 mL in two months) at 8.0 Log 10 CFU mL −1 twice a week for two months increased A. cepa total dry weight (69 ± 13 mg) compared with total dry weight (38 ± 5.0 mg) obtained with the control with water.
