“…Moreover, a previous study has also reported that phoD ‐harboring bacterial abundance and diversity could be promoted by hydrolyzing phytate (Lagos et al, 2016). The P components, including TP and Pi, significantly affected the Po‐mineralizing‐related gene abundance in our study, findings that are in line with those of previous reports (Margenot et al, 2017; Ye et al, 2017). In addition, phoD gene abundance decreased as AP increased, which agrees with the finding that phoD gene abundance in soil planted with soybean decreases with a higher AP (Fraser, Lynch, Gaiero, Khosla, & Dunfield, 2017), but disagrees with the report that phoD gene abundance in soybean‐maize rotation soils increases with a higher AP content (Hu et al, 2018).…”

“…In this study, alkaline phosphatase and phytase activity increased with a higher Pi content, as expected (Ye, Li, Zhang, Zheng, & Dai, 2017). However, alkaline phosphatase and phytase activities decreased as Po increased, which differs from a study that demonstrated that alkaline phosphatase and phytase activity in soils under different fertilization treatments increased as Po increased (Ye et al, 2017). Moreover, the finding that alkaline phosphatase activity was higher in soils with a higher AP level is not in line with the result from previous study in which alkaline phosphatase presents a higher activity in soil with a relatively lower AP level (Luo et al, 2017).…”

“…The levels of P components and Po‐mineralizing‐related enzyme activity determine soil fertility (Hu et al, 2018; Luo et al, 2017; Wei et al, 2019). In this study, alkaline phosphatase and phytase activity increased with a higher Pi content, as expected (Ye, Li, Zhang, Zheng, & Dai, 2017). However, alkaline phosphatase and phytase activities decreased as Po increased, which differs from a study that demonstrated that alkaline phosphatase and phytase activity in soils under different fertilization treatments increased as Po increased (Ye et al, 2017).…”

“…These differences might be due to different fertilization regimes. The soils collected in this study were from fields with irregular fertilization treatments or even natural soils on a large spatial scale, whereas soil samples in other studies are from areas under meticulous management and quantitative fertilization (Luo et al, 2017; Margenot et al, 2017; Ye et al, 2017). In fields on a large spatial scale, more unknown/known factors could affect the relationships between the content of P components and Po‐mineralizing‐related enzyme activity.…”

Spatial differences in soil microbial diversity caused by pH ‐driven organic phosphorus mineralization

et al. 2020

Microbial diversity response to abiotic and biotic factors provides a sensitive indicator for estimating the potential stability and degradation of soils in agro‐ecosystems. To determine the effects of pH on organic phosphorus mineralization and microbial diversity, phospholipid fatty acid analysis, quantitative polymerase chain reaction (qPCR), and multiple ecological analyses were performed. Significant correlations were found between phosphorus components and alkaline phosphatase, phytase, and pH, between phoD and phytase, between bpp and alkaline phosphatase. phoD and bpp gene abundance presented significant linear relationships with soil pH and microbial diversity. Abiotic and biotic factors explained 25.1% of the total variation in organic phosphorus‐mineralizing‐related gene abundance, and abiotic factors accounted for 13.2% of the total variation in microbial community composition. Soil pH was the determinant, accounting for 11.2 and 7.7% of the total variation in organic phosphorus‐mineralizing‐related gene abundance and microbial community composition, respectively. Our results emphasized that the phosphorus components, pH, and organic phosphorus‐mineralizing‐related gene abundance were responsible for organic phosphorus‐mineralizing‐related enzyme activity. To our knowledge, this is the first report that pH is a key factor in directly and indirectly determining organic phosphorus‐mineralizing‐related gene abundance, which in turn affects microbial diversity, on a large spatial scale. The differences in phosphorus components, enzyme activity, organic phosphorus‐mineralizing‐related gene abundance, microbial community composition and diversity caused by pH might explain crop yield reduction.

“…These results may also be related to fertilization, since it may have deprived the activity of this enzyme. Ye et al (2017) reported a reduction of the acid phosphatase activity, and associated this result with the excess P available in the soil. This fact is corroborated by the present study, in which the soil had much higher levels of P (28.2 mg dm -3 ) than those required for soybean cultivation.…”

The objective of this work was to evaluate the quality of the soil and its relation with soybean (Glycine max) yield in an integrated crop-livestock system (ICLS), with intercropping between grasses and legumes in the pasture phase. The experiment was carried out in the state of Mato Grosso, Brazil, on a dystrophic Oxisol, in which grasses (Megathyrsus maximus 'BRS Tamani' and Urochloa brizantha 'BRS Piatã'), intercropped with cowpea (Vigna unguiculata 'BRS Tumucumaque') and pigeon pea (Cajanus cajan 'BRS Mandarim'), were cultivated after soybean harvest. A randomized complete block design was used, with three replicates, in a split-plot arrangement, in which grasses were considered as plots, and legumes as subplots. Legume intercrops provided increases of C and total N stocks. The intercrops caused the increase of C and N of the microbial biomass, whereas the single cultures contributed to stress in the soil microbiota. The activity of the urease enzyme was sensitive to management changes in the short term, but acid phosphatase and β-glucosidase were poorly sensitive indicators. Soil quality is high with intercropping between grasses and legumes, with positive effects on soybean grain yield.
