“…This is in accordance with previous studies showing that AMF presence can improve the efficiency of fertilizer uptake and limit nutrient leakage (Cozzolino et al. ), and that AMF can also play a role in protection against plant pathogens (Miransari ), thus reducing plant C losses.…”

“…The AMF thus more than compensated for the C they received from their hosts, suggesting a positive influence of AMF beyond enhancing nutrient uptake in low nutrient environments. This is in accordance with previous studies showing that AMF presence can improve the efficiency of fertilizer uptake and limit nutrient leakage (Cozzolino et al 2013), and that AMF can also play a role in protection against plant pathogens (Miransari 2011), thus reducing plant C losses.…”

Biomass production efficiency (BPE), the ratio of biomass production to photosynthesis, varies greatly among ecosystems and typically increases with increasing nutrient availability. Reduced carbon partitioning to mycorrhizal fungi (i.e., per unit photosynthesis) is the hypothesized underlying mechanism, as mycorrhizal abundance and plant dependence on these symbionts typically decrease with increasing nutrient availability. In a mesocosm experiment with Zea mays, we investigated the effect of nitrogen (N) and phosphorus (P) addition and of mycorrhizal inoculation on BPE. Photosynthesis and respiration were measured at mesocosm scale and at leaf scale. The growth of arbuscular mycorrhizal fungi (AMF) was assessed with ingrowth bags while also making use of the difference in δ C between C plants and C soil. Mesocosms without AMF, that is, with pasteurized soil, were used to further explore the role of AMF. Plant growth, photosynthesis, and BPE were positively affected by P, but not by N addition. AMF biomass also was slightly higher under P addition, but carbon partitioning to AMF was significantly lower than without P addition. Interestingly, in the absence of AMF, plants that did not receive P died prematurely. Our study confirmed the hypothesis that BPE increases with increasing nutrient availability, and that carbon partitioning to AMF plays a key role in this nutrient effect. The comparison of inoculated vs. pasteurized mesocosms further suggested a lower carbon cost of nutrient uptake via AMF than via other mechanisms under nutrient rich conditions.

“…In addition to increasing P uptake, the symbiosis between roots and mycorrhizal fungi can make plants more resistant to water stress (Zarik et al, 2016), stimulate biological nitrogen fixation (Whabi et al, 2016), increase tolerance to heavy metals (Hritozkova et al, 2016), promote soil aggregation (Leifheit;Verbruggen;Rillig, 2015) and even mitigate adverse effects of soil pH (Moreira;Siqueira, 2006). Therefore, the mycorrhizal fungi play an important role in the integrated management of soil fertility (Cozzolino;Meo;Piccolo, 2013).…”

Phosphorus is a key-nutrient in the fertility management of highly weathered tropical soils. So, this work was carried out with the objective of evaluating the influence of the interaction between P doses, mycorrhizal inoculation and historical land use on soybean growth and P uptake in five Latosols (Oxisols) with contrasting chemical, physical and mineralogical properties under a continuous long-term phosphate fertilization (more than 15 years). The plants were cultivated in 4.5L-plastic pots containing 4 kg of soil in a completely randomized design, four replications and 2x2x2 factorial scheme with two P doses; and with or without mycorrhizal inoculation; and soils cultivated for long periods and non-cultivated (under native vegetation). There were two cultivations of ten weeks each. Shoot dry mass, P content and accumulation in the shoot dry mass were evaluated after each cultivation period. The cultivation history reduced the response to P application and inoculation. The soybean response to inoculation was greater in cultivated soils and when the lower P dose was applied. The soybean response magnitude to these variables was different among the studied Latosols. The mineralogical and chemical attributes of the Latosols were determinants.Index terms: Mycorrhiza; Latosols (Oxisols); available P; long-term cultivation. RESUMOO P é um nutriente chave no manejo da fertilidade de solos tropicais altamente intemperizados. Este trabalho foi conduzido com o objetivo de avaliar a influência da interação entre doses de P, inoculação micorrízica e histórico de uso do solo no crescimento da soja e absorção de P em cinco Latossolos com atributos físicos, químicos e mineralógicos contrastantes recebendo adubação fosfatada por longo período (> 15 anos). As plantas foram cultivadas em potes plásticos (4,5 L) contendo 4 kg de solo em um delineamento inteiramente casualizado, quatro repetições e esquema fatorial 2x2x2 correspondente a: duas doses de P; com e sem inoculação micorrízica; solos previamente cultivados e não cultivados (sob vegetação nativa). Foram realizados dois cultivos de dez semanas cada. Após cada um dos cultivos, avaliaram-se a massa seca da parte aérea, concentração e acúmulo de P na parte aérea. O cultivo do solo reduziu a resposta à aplicação de P e inoculação. A resposta da soja à inoculação foi maior nos solos cultivados e quando a menor dose de P foi aplicada. A magnitude dessas respostas foi diferente entre os Latossolos estudados, sendo os atributos mineralógicos e químicos dos Latossolos determinantes.Termos para indexação: Micorrizas; Latossolos; P disponível; cultivo do solo.

“…The mechanism of increased P uptake by Arbuscular mycorrhizal fungi has been attributed to the fungal extra radical hyphae growing beyond the phosphate depletion zone that develops around the root (Smith and Read 2008). Positive effects of arbuscular mycorrhizal fungi inoculation on the growth and P nutrition of crops have been reported (Cozzolino et al 2013;Dare et al 2010). Many mycorrhizal inoculants have been produced on a commercial scale, mostly in the US and Europe.…”

“…Many mycorrhizal inoculants have been produced on a commercial scale, mostly in the US and Europe. Rhizophagus (formerly Glomus) intraradices and Funneliformis (formerly Glomus) mosseae (Kruger et al 2012) are some of the common mycorrhizal inoculants which have been shown to increase P uptake in diverse crop plants (Dare et al 2010;Cozzolino et al 2013). Some other fungi such as Aspergillus and Penicillium species are able to solubilise inorganic phosphate and mineralise organic phosphate by secreting organic acids and producing phosphatase enzymes (Wang et al 2015).…”
