“…However, more recently, it has been widely applied for highly acidic soils. Gypsum addition significantly ameliorates the Ca 2+ and reduces the Al 3+ toxicity, while no effect has been reported on soil pH [ 16 ]. Mushroom residue is characterized by a low toxic content while having a higher content of organic matter [ 17 ].…”

Soil fungi play a critical role in plant performance and soil nutrient cycling. However, the understanding of soil fungal community composition and functions in response to different nutrients management practices in red soils remains largely unknown. Here, we investigated the responses of soil fungal communities and functions under conventional farmer fertilization practice (FFP) and different nutrient management practices, i.e., optimization of NPK fertilizer (O) with soil conditioner (O + C), with lime and mushroom residue (O + L + M), and with lime and magnesium fertilizer (O + L + Mg). Illumina high-throughput sequencing was used for fungal identification, while the functional groups were inferred with FUNGuild. Nutrient management practices significantly raised the soil pH to 4.79–5.31 compared with FFP (3.69), and soil pH had the most significant effect (0.989 ***) on fungal communities. Predominant phyla, including Ascomycota, Basidiomycota, and Mortierellomycota were identified in all treatments and accounted for 94% of all fungal communities. The alpha diversity indices significantly increased under nutrients management practices compared with FFP. Co-occurrence network analysis revealed the keystone fungal species in the red soil, i.e., Ascomycota (54.04%), Basidiomycota (7.58%), Rozellomycota (4.55%), and Chytridiomycota (4.04%). FUNGuild showed that the relative abundance of arbuscular mycorrhizal fungi and ectomycorrhizal fungi was higher, while pathogenic fungi were lower under nutrient management practices compared with FFP. Our findings have important implications for the understanding of improvement of acidic soils that could significantly improve the soil fungal diversity and functioning in acidic soils.

“…According to the manual of fertilization for V. corymbosum cultivated in southern Chile ( Pinochet et al., 2014 ), the maximum availability of exchangeable Al is 0.2 cmol + kg -1 , above which the V. corymbosum presents Al-toxicity. Likewise, according to Alarcón-Poblete et al. (2019) , different cultivars of V. corymbosum presented leaf morphology alterations as well as photochemical and biochemical damages when grown in soil containing 22% of Al saturation.…”

“…The presence of Al 3+ triggers a cascade of molecular, physiological and morphological changes in V. corymbosum , culminating in reduced productivity and yield ( Reyes-Díaz et al., 2010 , 2011 ; Inostroza-Blancheteau et al., 2011a , b ; Inostroza-Blancheteau et al., 2013 ; Ulloa-Inostroza et al., 2016 ). Indeed, gypsum amendments are frequently used to ameliorate Al 3+ toxicity in V. corymbosum ( Alarcón-Poblete et al., 2019 , 2020 ). According to the manual of fertilization for V. corymbosum cultivated in southern Chile ( Pinochet et al., 2014 ), the maximum availability of exchangeable Al is 0.2 cmol + kg -1 , above which the V. corymbosum presents Al-toxicity.…”

We aimed to evaluate the facilitation effects of an aluminum (Al) hyperaccumulator species bearing cluster roots, Gevuina avellana, on the seedling growth and performance of an Al-intolerant and phosphorus (P)-deficient-sensitive plant, Vaccinium corymbosum. For this, seedlings of G. avellana and V. corymbosum were grown alone or together as follows: i) two G. avellana seedlings, ii) one G. avellana + one V. corymbosum and iii) two V. corymbosum, in soil supplemented with Al (as Al2(SO4)3) and in the control (without Al supplementation). We determined relative growth rate (RGR), photosynthetic rate, chlorophyll concentration, lipid peroxidation and Al and nutrient concentration [Nitrogen (N), P, potassium (K), calcium (Ca), magnesium (Mg), sodium (Na), manganese (Mn), iron (Fe), copper (Cu), zinc (Zn), and sulfur (S)] in leaves and roots of both species. The results showed that, in general, G. avellana did not assist V. corymbosum to enhance its RGR nor reduce its Al uptake. However, G. avellana assisted V. corymbosum in enhanced N acquisition and, consequently, to increase its chlorophyll concentration and photosynthetic rate. Besides, V. corymbosum had lower lipid peroxidation in leaves when grown in the soil with high Al supplementation in association with G. avellana. Our results suggest a facilitating effect of G. avellana to V. corymbosum when grown in soils with high Al concentration, by enhancing chlorophyll concentrations and photosynthetic rate, and decreasing the oxidative damage to lipids.
