Zinc and copper fractions in Oxisols of different textures fertilized with pig slurry

At high soil concentrations, copper (Cu) is toxic to plant development. Symbiosis carried out between microorganisms and plant species are alternatives to minimize plant toxicity in copper contaminated soil. The present study aimed to select species of arbuscular mycorrhizal fungi for the development of wheat plants in copper contaminated soil. The experimental design was completely randomized in a 4 × 6 factorial arrangement, with four sources of inocula: three species of arbuscular mycorrhizae (Acaulospora colombiana, Gigaspora Margarita and Rhizophagus clarus) and one without inoculum (control), and six doses of copper in the soil (0, 80, 160, 240, 320, and 400 mg kg-1), with seven replications. Plant height, root length, root volume, root dry mass, specific surface area, average root diameter, root, shoot and grain Cu content and mycorrhizal colonization rate were evaluated. Root dry mass and mycorrhizal colonization were negatively affected by high Cu doses in the soil. The mycorrhizal isolates Acaulospora Colombiana and Gigaspora Margarita provide greater wheat height, root length and specific surface area and lower Cu content. Mycorrhizal colonization with the fungi Acaulospora Colombiana, Gigaspora Margarita and Rhizophagus clarus results in lower copper content in wheat shoots and grains.

Copper is a micronutrient essential for plant growth since it is part of the constitution of enzymes and proteins. However, it can become toxic to plants when in high concentrations in the soil. The association between microorganisms and plants is an alternative for reducing the negative effects of excess copper on plants. The objective of this work was to determine the influence of inoculation and co-inoculation of arbuscular mycorrhizal fungi and Azospirillum brasilense in a wheat crop grown on soil contaminated with copper. The experimental design used was entirely randomized in a bifactorial arrangement of 5 x 2, with five sources of inocula, (Azospirillum brasilense; Acaulospora colombiana; Gigaspora margarita; Acaulospora colombiana + Azospirillum brasilense; Gigaspora margarita + Azospirillum brasilense;), two doses of copper (0 = natural soil content and 400 mg kg-1), and eight replicates. We evaluated the height of plants, number of tillers, root length, root volume, dry root mass, specific surface area, average root diameter, copper content in the root, straw and grain, productivity, and percentage of mycorrhizal colonization. The inoculation with A. brasilense increases the number of tillers, plant height, and productivity compared to mycorrhizal fungi. The co-inoculation of these microorganisms does not contribute positively to these evaluated parameters, regardless of the dose of Cu applied to the soil. Co-inoculation of A. brasilense with mycorrhizal fungi does not reduce copper in the aerial part of wheat plants, regardless of the evaluated species, even in soil contaminated with copper.

Zinc and copper fractions in Oxisols of different textures fertilized with pig slurry

Abstract: HIGHLIGHTS Higher concentrations of exchangeable Zn were found in areas with pig slurry application. No higher concentrations of Cu were found in the exchangeable fraction in areas using pig slurry. In all study areas, it was observed that more than 70% of Cu is in recalcitrant forms.
