| Biosolids have been reported to increase yields and supply plant nutrients. However, complying with health and environmental standards is necessary before applying biosolids to land. Thus, sludge stabilization is required to make biosolids safe enough for their agricultural use. Side effects of stabilization processes on agronomic features of sewage sludge are not quite known, although their understanding is essential for biosolids management. Based on a model equivalent to the Mitscherlich equation, effects of the most common processes for sludge stabilization were evaluated (composting, liming, heat-drying and solar irradiation) in relation to the agronomic effectiveness of biosolids to yield Lolium perenne L. on two tropical soils, with NH4H2PO4 as a... |

| ABSTRACT Sewage sludge is rich in organic matter and nutrients for the plants, and can be used in pineapple production, but there are few studies with scientific evaluation of possible inorganic and biological contaminants in pineapple plantations. In view of the above, this study aimed to evaluate the contamination of the soil and in fruits of pineapple fertilized with sewage sludge. The study was conducted in the municipality of Janaúba-MG. Treatments were arranged in a randomized block design, with four replicates, in a 2 x 5 factorial scheme, consisting of two different fertilizers: sewage sludge (SS) and mineral fertilizers (MF), and five pineapple varieties (Pérola, Vitória, Smooth Cayenne, MD-2, Fantastic IAC). Nitrogen was adopted as the base... |

| The current study was aimed at investigating the use of different fertilizers - dicalcium phosphate, biosolid and quail feces - as a strategy for water fertilization in Daphnia sp production. It was used twenty-four 100-L tanks of asbestos cement distributed in a completely randomized split-plot design with six replicates, with plots in the three kinds of fertilizers (biosolid, dicalcium phosphate, and quail feces) and a control without fertilization (WF) and subplots at the times of assessment (days 8 and 13). It was assessed the biomass production of Daphnia sp. and the following water quality parameters: chlorophyll a, electrical conductivity, pH, dissolved oxygen, temperature, ammonia and organic nitrogen, total phosphorus and total hardness. There was... |

| The generation of waste has gradually increased due to the large swine production and with this comes the concern about the final destination of the product. This study aimed to analyze the initial behavior of Eucalyptus super clone (AEC 1528), fertilized with swine sludge and compared to chemical fertilizer. The experiment was conducted in a completely randomized design with 5 treatments and 3 replications, with the volumes: 1.25, 2.5, 5 liters; 0 liters of sewage sludge and chemical fertilizer. The plants were irrigated with water from a well at the Rio Verde University, increasing the amount according to plant growth. After 120 days, we evaluated the height of the plants, stem diameter, relation between stem diameterand plantsheight, weight of the fresh... |

| The application of sewage sludge is a concern because it may affect the quality of organic matter and microbiological and biochemical soil properties. The effects of surface application of sewage sludge to an agricultural soil (at 18 and 36 t ha-1 dry basis) were assessed in one maize (Zea mays L.) growing season. The study evaluated microbial biomass, basal respiration and selected enzymatic activities (catalase, urease, acid and alkaline phosphatase, and β-glucosidase) 230 days after sewage sludge application and infrared spectroscopy was used to assess the quality of dissolved organic matter and humic acids. Sewage sludge applications increased the band intensity assigned to polysaccharides, carboxylic acids, amides and lignin groups in the soil. The... |

| ABSTRACT The use of organic residues can improve soil chemical and physical conditions and plant growth. However, these residues often contain heavy metals that can interfere with growth. Here, a pot experiment was performed to compare the effects of organic compound (OC) containing a high nickel (Ni) load with those of a mineral Ni source (NiCl2, a soluble salt) on the production, quality and nutritional status of strawberry and on soil chemistry. Six dosages of Ni (0, 9, 18, 36, 72 and 144 mg kg-1) were added to the soil using both OC and NiCl2. The use of high-Ni OC resulted in increased productivity and fruit weight, whereas the soluble NiCl2 salt caused reduction in fruit weight. Application of NiCl2 at concentrations >18 mg kg-1 also caused... |

| ABSTRACT Industrial and organic residues cause environmental impacts at various levels. However, these residues present potential to correct soil acidity and fertility. Considering the possibility of using these alternative sources, the objective of this study was to analyze the quality of scarlet eggplant seeds produced with the use of industrial waste. The experiment was carried out in a greenhouse. We used scarlet eggplant seeds (Solanum gilo), cv. ‘Verde-Claro’, and the soil was Typic Hapludox. The experimental design was randomized blocks, in a factorial distribution (3x4x5), being three soil variations [(pure soil (S), soil + cattle manure (SE) and, soil + sewage sludge (SL)], four corrective treatments [without correction (C1), limestone (C2), steel... |

| Wastewater treatment generates large amounts of sewage sludge, which when are disposed in highly degraded soils (with a complete loss of the A horizon and a great part of the B horizon), represent an interesting alternative to recover the aggregate level into soil. Within the hierarchy of soil systems, the aggregate level is the one that integrates soil properties that are directly related to soil sustainability. The aim of this study was to determine the effect of different dose of sewage sludge and an annual legume on the structural recovery of a degraded Alfisol. Sludge was added to soil at 0, 15, 30 and 60 t ha-1 in treatments with and without yellow serradela (Ornithopus compressus L.). After 6 months, the following structural indicators were... |
