“…P. bilaiae has also been reported to stimulate production of root hairs (Gulden and Vessey 2000) and increase overall root growth (Vessey and Heisinger 2001). Inoculation with P. bilaiae has improved growth of many cropping species including wheat (Kucey 1987(Kucey , 1988Anstis 2004), canola , and grain (Kucey 1987;Gleddie 1993) and pasture (Beckie et al 1998;Rice et al 2000) legumes. A commercial inoculant product based on P. bilaiae (JumpStartÔ), has been successfully used by Canadian wheat growers to improve crop P nutrition for at least 15 years.…”

The most effective isolate was identified as a novel strain of P. bilaiae (Wakelin et al 2004b), the same species that is being used successfully in North America to promote higher P-fertiliser efficiency and increase plant production Beckie et al 1998;Rice et al 2000). The Australian strain of P. bilaiae significantly increased carbonate-extractable P in soil (pH 7.3) by 23% compared with the uninoculated control, improving P uptake in lentils in three neutral to alkaline cropping soils (Wakelin et al 2007b).…”

Potential to improve root access to phosphorus: the role of non-symbiotic microbial inoculants in the rhizosphere

Phosphate anions in soil solution are extremely reactive and may be rapidly immobilised in the soil through precipitation and adsorption reactions, resulting in sparingly soluble forms of phosphorus (P) that are essentially unavailable to plants. This low P-fertiliser efficiency is often offset through high application rates, which are economically and environmentally unsustainable and not an available option for organic producers. Microorganisms play a fundamental role in the biogeochemical cycling of inorganic and organic P in the rhizosphere and detritusphere. Free-living rhizosphere microbes can directly increase the availability of phosphate to plant roots via mechanisms associated with solubilisation and mineralisation of P from inorganic and organic forms of total soil P. These include releasing organic anions, H + ions, phosphatases, and cation chelating compounds into the rhizosphere. Many soil-borne microbes also increase P availability indirectly by producing phytohormones that increase root density and function. There is increasing interest worldwide in the use of rhizosphere microorganisms as inoculants to increase P availability for agricultural production. Recent research has focussed on developing actively sporulating Penicillium fungi known to express mechanisms to enhance P mobilisation and therefore, considered to be a key component of the mycoflora involved in P cycling in soils. Penicillium species do not exhibit specific plant or soil associations and have a broad agro-ecological range, indicating their potential to be developed as inoculants for a range of plant production systems. Successful adoption of microbial inoculants requires a thorough understanding of their rhizosphere ecology, genetic stability, and the mechanisms associated with enhancing P availability in soils and plant-growth promotion. This will provide a better understanding of which inoculants to use under particular agro-ecological conditions for increased efficacy and consistent performance.

Phosphorus, other elements and natural resources are scarce, and so it is necessary to find alternative strategy to increase availability of nutrients for plants. One possible way could be application of so-called bioeffectors (BE) which should improve the mobilisation of nutrients (especially phosphorus) from less available forms in soil, improve plant growth and contribute to mycorrhiza development. BEs are commercially supplied products which contain active substances (live microorganisms and active natural compounds). BEs can be used in organic agriculture, because their application represents no risk for the environment. Several studies and experiments are focused on impact of bioeffectors' application and their active compounds on plants. Experiments were performed under different conditions (field, pot, greenhouse), on various testing plants and on various bioeffectors. These BEs have been used as a fertilizer, fungicide or molluscicide and they were applied either to soil, seed or leaf. Application should increase growth of root system and above-ground part of plants and also nutrient uptake. These products are developed for a wide variety of crops (e.g. maize, wheat, tomatoes, rape, spinach, grass, ornamentals). This review summarizes the most recent knowledge in this scientific field. Use of Active Microrganisms in Crop Production-A ReviewZlata Holečková*, Martin Kulhánek and Jiří Balík Department of Agro-Environmental Chemistry and Plant Nutrition, Faculty of Agrobiology, Food and Natural Resources, Czech University of Life Sciences, Prague, Czech RepublicMycorrhiza is highly effective in absorbing nutrients from the soil, especially for nitrogen and phosphorus. Nitrogen and phosphorus are often limited in supply and fungal hyphae are able to absorb these nutrients more efficiently and from greater area of soil than the roots, which leads to increased plant growth. This causes mutually beneficial linkage between plants and fungi, the sugars (organic carbon) formed during photosynthesis are transported to the roots and the fungi are taken and the nutrients are absorbed by fungal hyphae from the soil and are transported into plants [10,11]. Arbuscular mycorrhizal fungi colonise most agricultural species (exceptions include Brassica spp., and Lupinus spp.) and play an important role in the phosphorus nutrition of many farming systems worldwide, especially on soils with low available phosphorus [3]. Literature ReviewExamples of plant strategies for phosphorus obtaining: One alternative strategy in plant production can be use of unmycorrhizal organism's P mobilizing nutrients, which should help to increased nutrient availability for plants. These substances are so-called bioeffectors.

“…In this study, it was not possible to relate a higher plant growth with a higher P solubilisation with the combination of SS and P. bilaii. Promotion of plant growth by P. bilaii inoculation without a concomitant increase in the P content of these plants has been found in several studies [22,24,[38][39][40][41], showing that the P. bilaii root growth increase may be related to mechanisms other than P uptake, such as phytohormone production or other possible mechanisms against abiotic stresses [42][43][44]. P. bilaii effect for the first 10-18 DAS was gradually decreased.…”

Background: Penicillium bilaii may enhance P availability to plants, since it has been shown to increase plant growth and P uptake. There is currently increasing interest in using microorganisms to promote P mobilisation from organic P sources. An investigation was conducted to determine the effects of P. bilaii on P uptake and growth of wheat in the presence and absence of sewage sludge. Two soils differing in P contents and pH were used, as it was hypothesised that these affect the efficiency of P mobilisation.Methods: A pot experiment, in which wheat was grown for 35 days in a moderately acidic soil of low P status and a calcareous soil of moderate P status, was conducted. A full factorial design was used with two non-sterilised soils, three amendments [control, sewage sludge and triple superphosphate (TSP)] and two P. bilaii treatments (with/ without). Shoot and root length, biomass and nutrient contents were analysed in plant, whereas soil samples were analysed for water-extractable P and soil pH. Results:The shoot length and root biomass of wheat were significantly higher when sewage sludge was applied in combination with P. bilaii seed inoculation, in the moderately acidic soil. In contrast, shoot length and biomass and root biomass were higher with P. bilaii compared to the control, but no synergistic effects of P. bilaii and the organic P source were observed in the calcareous soil. A systematic, but not significant increase in total P uptake was found for all treatments inoculated with P. bilaii and for both soils, with the control of the low fertility moderately acidic soil being a notable exception. Conclusions:Sewage sludge was seen to be an efficient P source, on par with TSP in the moderately acidic soil. In the calcareous soil, the P. bilaii treatments without added P fertilisers had the greatest effect, with both root and shoot biomass increasing significantly.
