“…Values above those proposed by CONAMA are toxic to microorganisms, plants, and animals (Andreazza et al, 2013) and cause a reduction in plant growth due to morphological and physiological changes (Mateos-Naranjo et al, 2013;Guimarães et al, 2016). However, the copper content in the soil is not affected by inoculation with A. brasilense (Figure 1), and its concentration and availability in the soil result from the balance between the reactions of precipitation, dissolution, complexation, and adsorption, which are influenced by several factors, such as soil type, climate, culture, and chemical form of the elements (Medina et al, 2018;Souza et al, 2018).…”

Copper (Cu) is a metal that can become toxic to sorghum when present in high concentrations in the soil. The use of plant growth-promoting rhizobacteria can be an alternative for the development of sorghum [Sorghum bicolor (L.) Moench] in soil contaminated with copper. The objective of this study was to determine the effect of Azospirillum brasilense inoculation on the development and copper levels of sorghum cultivated in soil contaminated with Cu, enabling the reuse of these areas. The experimental design was randomized blocks in a factorial arrangement (9 × 2), with nine doses of copper [(0: natural content of the soil), 30, 60, 90, 120, 150, 180, 240, and 300 mg of copper kg-1 of soil] with and without A. brasilense inoculation, with six replicates. In the treatment without inoculation, a dose of 200 kg-1ha was applied. Plant height (PH), stem diameter, dry mass of the air part (DMAP), volume, length, and root dry mass (RDM), relative index of chlorophyll a and b, and copper contents in DMAP and RDM were evaluated. The inoculation with A. brasilense allows a higher index of chlorophyll a and b and the development of the aerial part of the sorghum, reducing copper content in the aerial part, enabling the reuse of soil containing 52.5% clay, contaminated with up to 300 mg of copper kg-1 of soil. Inoculation with A. brasilense increases the specific surface area (SSA) of sorghum roots compared with non-inoculated plants grown only with nitrogen fertilization in soil contaminated with copper.

“…The increase in the pH value of cattle manure may be related to the increase in organic matter and to the lower soil Al³ + content. According to Medina et al (2018), as the pH increases, the number of negative charges increases, and as the pH decreases, there is an increase in the number of positive charges.…”

Nutrient management becomes essential in soils with low natural fertility, so the use of organic fertilizers can improve chemical properties of soil and reduce production costs. The objective of this study was to evaluate the effect of different fertilization sources on the chemical properties of soil under cassava cultivation. The experiment was conducted between 2017/2018 in the community of Boa Esperança, Santarém-PA using the cultivar Bem-te-vi, in the randomized block design with 4 treatments: T1 (without fertilization), T2 (fertilization NPK), T3 (organic fertilization with poultry manure), T4 (fertilization with cattle manure), with 5 replicates. The soil samples were analyzed for the contents K+, Ca²+, pH in H2O and KCl, Al³+ and soil organic carbon content (TOC). The data were submitted to analysis of variance and the means were compared by the Tukey test at 5% probability, using the software MINITAB© version 18. There were statistical differences between the treatments for all the chemical properties analyzed. The findings of the analysis were that fertilization with catle manure and NPK were the same and differed from the other treatments for the contents of K+, pH in H2O and KCl, for Ca²+ and TOC. The treatment without fertilization obtained the lowest values differing from the others, for Al³+. The source from NPK obtained the lowest content in the soil. The treatments with organic fertilizers had higher levels of the above nutrients in the soil. The chemical properties of the soil were altered from the different management systems for the cultivation of cassava.
