As the awareness on ecological impact of chemical phosphate fertilizers grows, research turns to sustainable alternatives such as implementation solubilizing bacteria (PSB), which make largely immobile phosphorous reserves in soils available for uptake by plants. In this review, we introduce mechanisms plants facilitate P-uptake and illustrate how PSB improve bioavailability nutrient. Next, effectiveness increasing plant biomass is assessed using a meta-analysis approach. Our review demonstrates that improved does not always translate height biomass. We show effect provide an added benefit when bacterial consortia compared single strains. Moreover, commonly reported species P-solubilization, Bacillus spp. Pseudomonas spp., are outperformed scarcely implemented Burkholderia Despite similar responses monocots eudicots, responsiveness varies within both clades. Remarkably, challenges common belief less effective under field conditions greenhouse conditions. This provides innovative insights identifies key questions future promote their agriculture.

The application of plant beneficial microorganisms is widely accepted as an efficient alternative to chemical fertilizers and pesticides. It was shown that annually, mycorrhizal fungi nitrogen-fixing bacteria are responsible for 5 80% all nitrogen, up 75% P acquisition. However, while the most studied soil frequently reported in scientific literature, role relatively understudied, although they primary organic matter decomposers govern carbon other elements, including P-cycling. Many can solubilize insoluble phosphates or facilitate P-acquisition by plants and, therefore, form important part commercial microbial products, with Aspergillus, Penicillium Trichoderma being efficient. In this paper, P-solubilization nutrition will be presented a special emphasis on their production application. Although topic has been repeatedly reviewed, some recent views questioned efficacy P-solubilizers soil. Here, we try summarize proven facts but also discuss further lines research may clarify our doubts field open new perspectives using particularly fungal P-solubilizing potential accordance principles sustainability circular economy.

Root phenotypes for improved nitrogen capture

Plant and Soil, Год журнала: 2023, Номер unknown

Опубликована: Окт. 4, 2023

Suboptimal nitrogen availability is a primary constraint for crop production in low-input agroecosystems, while fertilization contributor to the energy, economic, and environmental costs of high-input agroecosystems. In this article we consider avenues develop crops with improved capture reduced requirement fertilizer.

Inoculation of phosphate-solubilizing bacteria improves soil phosphorus mobilization and maize productivity

Nutrient Cycling in Agroecosystems, Год журнала: 2023, Номер 126(1), С. 21 - 34

Abstract Phosphate-solubilizing bacteria represent a bioalternative in making soil-immobilized phosphorus (P) available to plants, and consequently improve agriculture sustainability reduce nutrient pollution. In this study, we examined whether Rhizobium sp. B02 inoculation can affect the soil P fractions. Moreover, investigated how influences growth, physiological traits, productivity of maize crop. Field tests were carried out evaluate combined application strain reduced doses fertilizer. Soil fractionation was performed after crop harvesting, assessing dynamics. To study plant response, samplings three phenological stages—the vegetative stage 7 fully emerged leaves with leaf collars (V7), tassel (VT), reproductive maturity (R6). Using 50% fertilizer recommended, increased labile inorganic fraction by 14% compared control treatment at same dose, indicating that it favored Pi mobility. Under these conditions V7 VT stages, significantly improved shoot length (28 3%) dry weight (9.8 12%). grain yield 696 kg ha −1 using recommended rate fertilizer, phenocopying complete fertilization without inoculation. Therefore, replaced availability.
