“…They observed vermicompost was more efficient in reducing toxicity of Cu to the plants, since Cu is easily complexed with soil organic matter (SOM). High Cu concentrations in soils were also reported in areas with mango (Mangifera indica) trees, cultivated for more than 26 years in Pernambuco State (Silva, Nascimento, Biondi & Cunha, 2012), and with melon (Cucumis melo), cultivated for two years in Rio Grande do Norte State (Mendes, Duda, Nascimento, Lima, & Medeiros, 2010). In both cases, Cu contents were higher than the prevention value (60 mg kg -1 ) allowed by the Brazilian legislation (Conselho Nacional do Meio Ambiente [CONAMA], 2009) for Cu in soils.…”

Copper is a micronutrient for living organisms, but at high concentrations it may cause several deleterious effects. The objective of this study was to evaluate the behavior of agricultural crops to different concentrations of Cu in the soil. The species Triticum aestivum (wheat), Zea mays (maize), Oryza sativa (rice), Phaseolus vulgaris (dry bean), Glycine max (soybean), and Raphanus sativus (radish) were cultivated in the soils Typic Hapludox (TyHpx) and Rhodic Acrudox (RhAcx). The experiment was carried out in a greenhouse and the soils were set in pots in a completely randomized design, with four replicates per treatment adding the following Cu concentrations (as Cu-nitrate): 0, 75, 150, 300, 600, 800, 1000, 1200 mg kg-1 dry soil. Measurements of biological variables, such as shoot dry weight (SDW), plant height, stem diameter, and number of leaves were carried out, in addition to determining Cu content in the SDW. At the TyHpx, a decreasing order of tolerance to Cu phytotoxicity was: dry bean, maize, soybean, wheat, radish, and rice. However, at the RhAcx, the decreasing order was: maize, soybean, radish, wheat, dry bean, and rice. The species that revealed the highest sensitivity to high Cu concentrations in soil was rice and that with the lowest sensitivity was maize.

“…The climate of this region favors the development of vines and provides more than two harvests of different types of grapes for one year, boosting the demand for phosphate fertilizers and agricultural inputs (Arata et al 2017). Some studies have already determined the concentrations of P in that vineyard's soils and have asserted that the available fraction of this element is one of the highest ever reported in a tropical environment, and this can threaten the water bodies by leaching and eutrophication, consequently (Silva et al 2012, Preston et al 2016, Preston et al 2017.…”

Brazilian semi-arid tropical is responsible for the production and export of fine table grapes, but the demand for phosphate fertilizers and other agricultural inputs increases the cost of production and threatens local water bodies by leaching of phosphorus (P).The objectives of this study were to quantify the organic and inorganic fractions of P and to determine chemical and microbiological attributes related to its mineralization in soils cultivated with vines in São Francisco Valley. It was hypothesized that P fractions and microbial activity would increase in areas fertilized with phosphate. Soil samples from vines were collected in cultivated areas and in fallow systems. P fractionation, macro-elements analysis, microbial biomass phosphorus (Pmic), and phosphatase enzyme activity were determined and correlated with each other and with the total proportion of synthesized glomalin. In both treatments, the inorganic P fractions exceeded the organic ones, and the total phosphorus available in those soils was associated with the most recalcitrant fractions, reducing risks of leaching of this element and contamination of water bodies. Pmic was higher in the winery areas due to the presence of phosphate fertilizers and organic matter, hence the activity of alkaline phosphatase enzymes and the production of total glomalin increased respectively in three and four evaluated areas, indicating that P-mineralized bacteria and arbuscular mycorrhizal fungi have been positively affected by the current agricultural system.

“…Monocultures characterize the irrigated agricultural areas of the Brazilian semi-arid, high use of agricultural inputs and intensive use of the farm machine, causing soil degradation by erosion, salinization, and contamination by heavy metals and pesticides (Silva et al, 2012). Green manure allows the input of large amounts of biomass.…”

A B S T R A C TThe green manure, through the simultaneous sowing of different species, can be a strategy to mitigate the environmental impact due to the use of fertilizers in irrigated environments in the Brazilian semi-arid. This study aimed to evaluate the dry matter production and the nutrients concentration and accumulation by phytomass of two types of plant mixture and natural vegetation cultivated between lines of a mango orchard, in two soil systems management, during five production cycles. The experiment was conducted in a complete randomized block design with four replications and treatments arranged in subdivided plots scheme. The plots consisted of two soil management systems (tillage and no-tillage), and the subplots consisted of 3 types of green manures: plant mixture 1 (PM1); plant mixture 2 (PM2) and spontaneous vegetation (SV). The dry matter, contents, and accumulation of N, P, K, Ca, Mg and S were evaluated. Plant mixture, independent of their composition, produced higher amounts of dry phytomass compared with natural vegetation and, consequently, accumulated higher amounts of nutrients. The N and P contents were lower in the phytomass of the spontaneous vegetation and the plant mixture with a predominance of grasses and oilseeds, respectively, in the tillage systems. The Ca contents were higher in the plant mixture with a predominance of grasses and oilseeds (PM2), and Mg in the plant mixture with a predominance of legumes (PM1) and the spontaneous vegetation (SV).
