“…Lower doses of P application generally failed to increase Olsen-P content in soil, but application of 50% or 100% of recommended P brought significant change and increase P content at both stages. Lang et al (2018) also reported that P addition increased Olsen-P by 4-6 times when P was applied at the rate of 44 kg/ha and by 10-20 times at 131 kg/ha. Split application of P was statistically at par with basal application of 100% P which suggested that split application of P does not have any advantage over full basal application.…”

A field experiment was conducted between 2012-14 to investigate the effect of different phosphorus levels (control-no P, 33% P, 50% P, 100% P and 100% P in 3-splits of the recommended dose of P) and microbial inoculants (un-inoculated control, arbuscular mycorrhizal fungi, AM phosphate solubilising bacteria, PSB and AM+PSB) in maize-wheat system. The study revealed that the maize and wheat grain yields were increased by 20% and 40%, respectively, under 100% P which were significantly higher over control. The total P uptake by maize and wheat varies from 11.7â€“20.7 kg/ha and 17.7â€“32.4 kg/ha, respectively. The highest apparent recovery (AR) in both the crops was recorded when 50% P was added with AM+PSB inoculation whereas, a significant reduction in AR was recorded with increase in fertilizer P beyond 50% of recommended P. Agronomic efficiency was highest under 50% P averaged across microbial inoculants in both maize (32.5 kg grain/kg P) and wheat (78.5 kg grain/kg P). Grain yield of both maize and wheat was significantly and positively correlated with Olsen P content at tasseling (r = 0.30*) and panicle emergence (r = 0.35**). The higher P use-efficiency under 50% recommended P along with microbial inoculants suggests applying lower doses of P fertilizer along with microbial inoculants to achieve optimum yield in maize-wheat system without any adverse impact on soil fertility.

“…Plant roots lead to the selective enrichment of rhizosphere microorganisms due to environmental changes ( Berendsen et al, 2012 ; Lareen et al, 2016 ). Previous work have shown that P levels would affect bacterial communities under different soil types, plant species, and crop growth periods ( Huang et al, 2016 ; Lang et al, 2018 ; Long et al, 2018 ; Wang et al, 2018 ; Zhuang et al, 2020 ). We performed a longitudinal comparison of the changes across the entire life cycle of maize in two treatments.…”

“…Previous studies have shown that P fertilizer affects the diversity and community structure of fungi, but these works were carried out at a single time point only or under different soil types ( Fanin et al, 2015 ; Luo et al, 2015 ; Huang et al, 2016 ; Lang et al, 2018 ; Liu M. et al, 2018 ). Our research results demonstrated that there were no significant differences in the Shannon and Chao indexes of fungi ( Figures 1C,D ), while distinct changes in the community composition of fungi were observed ( Figures 2C,D ).…”

“…Moreover, a low P input (50 mg P 2 O 5 kg –1 ) increased the diversity of endophytic bacteria and a high P input (200 mg P 2 O 5 kg –1 ) increased the diversity of fungi in P-deficient paddy soils ( Long and Yao, 2020 ). In contrast, excessive P input (131 kg P ha –1 ) reduced the diversity of maize arbuscular mycorrhiza (AM) in the North China Plain ( Lang et al, 2018 ). However, these studies were carried out at a single time point.…”

Rhizosphere Microbial Communities Are Significantly Affected by Optimized Phosphorus Management in a Slope Farming System

et al. 2021

Soil rhizosphere microorganisms play crucial roles in promoting plant nutrient absorption and maintaining soil health. However, the effects of different phosphorus (P) managements on soil microbial communities in a slope farming system are poorly understood. Here, rhizosphere microbial communities under two P fertilization levels—conventional (125 kg P2O5 ha–1, P125) and optimal (90 kg P2O5 ha–1, P90)—were compared at four growth stages of maize in a typical sloped farming system. The richness and diversity of rhizosphere bacterial communities showed significant dynamic changes throughout the growth period of maize, while different results were observed in fungal communities. However, both the P fertilization levels and the growth stages influenced the structure and composition of the maize rhizosphere microbiota. Notably, compared to P125, Pseudomonas, Conexibacter, Mycobacterium, Acidothermus, Glomeromycota, and Talaromyces were significantly enriched in the different growth stages of maize under P90, while the relative abundance of Fusarium was significantly decreased during maize harvest. Soil total nitrogen (TN) and pH are the first environmental drivers of change in bacterial and fungal community structures, respectively. The abundance of Gemmatimonadota, Proteobacteria, and Cyanobacteria showed significant correlations with soil TN, while that of Basidiomycota and Mortierellomycota was significantly related to pH. Additionally, P90 strengthened the connection between bacteria, but reduced the links between fungi at the genus level. Our work helps in understanding the role of P fertilization levels in shaping the rhizosphere microbiota and may manipulate beneficial microorganisms for better P use efficiency.

“… 226 On the other hand, high nitrogen fertilization enhanced abundance of nitrification and denitrification genes in the surrounding soil with an ability to improve crop biomass and nitrogen content. Lang et al 227 found that when phosphorus fertilizer increased, the overall community richness of AMF and bacteria dropped, while fungal and bacterial gene copies may get enhanced.…”

The interaction of silicon and soil microorganisms stimulates crop enhancement to ensure sustainable agriculture. Silicon may potentially increase nutrient availability in rhizosphere with improved plants’ growth, development as it does not produce phytotoxicity. The rhizospheric microbiome accommodates a variety of microbial species that live in a small area of soil directly associated with the hidden half plants’ system. Plant growth-promoting rhizobacteria (PGPR) play a major role in plant development in response to adverse climatic conditions. PGPRs may enhance the growth, quality, productivity in variety of crops, and mitigate abiotic stresses by reprogramming stress-induced physiological variations in plants via different mechanisms, such as synthesis of indole-3-acetic acid, 1-aminocyclopropane-1-carboxylate deaminase, exopolysaccharides, volatile organic compounds, atmospheric nitrogen fixation, and phosphate solubilization. Our article eye upon interactions of silicon and plant microbes which seems to be an opportunity for sustainable agriculture for series of crops and cropping systems in years to come, essential to safeguard the food security for masses.
