1. Nutritional diagnosis of ‘Montenegrina’ mandarin orchards at the southern Brazil
ABSTRACT The correct nutrition of orchards from fertilizer management directly influences fruit yield. Therefore, the objective was to evaluate the nutritional status of orchards of the ‘Montenegrina’ mandarin (Citrus deliciosa Tenore) grafted on Poncirus trifoliata Raf. in southern Brazil. The study included analyzes of soil and leaf tissue from 58 comm

2. Steel slag and phosphate nutrition of corn inoculated with arbuscular mycorrhizal fungi
Resumo: O objetivo deste trabalho foi avaliar o efeito do uso de escória de siderurgia como corretivo da acidez do solo e de fungos micorrízicos associados à adubação fosfatada em plantas de milho. O trabalho foi conduzido em casa de vegetação, tendo-se utilizado vasos com 3 kg de Latossolo Vermelho distrófico, em arranjo fatorial 4x5x2, com quatro t

3. Phytoextractor Potential of Cultivated Species in Industrial Area Contaminated by Lead
ABSTRACT: High growth rate is one of the criteria used for the selection of species to be used in metal phytoextraction programs. This study was carried out to characterize the growth characteristics of sunflower (Helianthus annuus L.), castor bean (Ricinus communis L.), corn (Zea mays L), and vetiver [Vetiveria zizanioides (L.) Nash] grown on a soil contami

4. Effects of surface application of dolomitic limestone and calcium-magnesium silicate on soybean and maize in rotation with green manure in a tropical region
Although lime is currently the material most frequently used to ameliorate soil acidity in Brazil, silicate could efficiently replace this source because of its greater solubility and its greater silicon content, which are beneficial for plant development. This study aimed to evaluate the effects of superficial lime and silicate application on soil chemical

5. Caracterização e classificação quanto ao risco ambiental do estéril da mina de cromita do município de Andorinha, Bahia
The mineral waste studied was host rock from a chromite mine located in Andorinha/Bahia, extracted and stockpiled in yards without specific application. Host rock was submitted to chemical analysis, XRD, SEM-EDS, IR and TGA and classified according to ABNT standards for solid waste classification. Analyses confirmed that this host rock, classified as ultraba

6. Composição química e propriedades funcionais no processamento de vinagres / Chemical composition and functional properties in the processing fo vinegar
The fruit vinegars increasingly become popular on the planet, being produced from various crops or their residues, using classical and modern techniques. These products have great variety of organic acids, vitamins, minerals, phenolic compounds and other elements with important physiological functions. Vinegar higher quality depends more on their secondary c

7. Classes granulométricas e modo de aplicação de calcário na cultura do milho / Size classes and ways of applying lime to corn crop
Lime particle size is key to soil correction as it defines the reactivity of the soil due to its low solubility. The lime presenting a particle size larger than 0,3 mm corrects soil acidity and enables soil residual effect whereas the finely ground lime presents a lower residual effect, however; it promotes soil acidity correction and can percolate in the la

8. Effect of silicate fertilization on soil and on palisade grass plants under grazing intensities
Application of calcium silicate (SiCa) as soil acidity corrective was evaluated in a Rhodic Hapludox soil with palisade grass conducted under pasture rotation system with different grazing intensities. Experimental design was complete randomized blocks with four grazing intensities - grazing intensities were imposed by forage supply (50, 100, 150 and 200 kg

9. Potencial da escória silicatada na correção da acidez do solo em plantio direto / Slag potential in soil acidity correction under no-tillage
The soil acidity correction under no-tillage systems is a barrier to be beaten in agriculture. The slag, 6,8 times more soluble than lime, could, because of its better solubility, dislocate in deeper soil layers and correct soil acidity there. This work had as objectives to evaluate the mobility in the soil layers of slag in a comparison with lime under no-t

10. ANÁLISE QUÍMICA DO LIXIVIADO DA ÁGUA DE XISTO EM UM LATOSSOLO VERMELHO ESCURO DISTRÓFICO
Industrial processes generate a series of products, often without applicability becomes waste that contribute to pollution of soil, air and water. Some products may be reused and / or processed into raw materials for other processes. In this context, analyzed the water of oil shale (a byproduct of the process of obtaining the oil shale) using an Instrumental

11. CORRECTION OF THE ACIDITY OF THE SOIL IN SUBSURFACE IN A OXISSOL OF FRANC-SANDY TEXTURE UNDER NO TILLAGE / CORREÇÃO DA ACIDEZ DO SOLO EM SUBSUPERFÍCIE EM UM LATOSSOLO DE TEXTURA FRANCO-ARENOSA SOB PLANTIO DIRETO
In tropical and subtropical areas, especially, where there is the dry period occurrence, the acidity subsurface (below the 10 cm) it has been pointed as one of the limitation causes to the growth of roots and the agricultural productivity. In the state of Rio Grande do Sul, in the last years, reports exist that areas under no tillage that don t present excha

12. Uso de resíduos vegetais em solos ácidos sob sistema de plantio direto
The Brazilian soils are characterized by low natural fertility, where the main chemical limitations are high acidity and low basic exchangeable cation saturation that can affect the majority of cash crop productions. Liming is the principal practice to reduce soil acidity and to increase basic cations in these soils with high pH-dependent cation exchangeable
