1. Characterization of the solid residue generated in the detoxification step of sugarcane bagasse hemicellulosic hydrolysate and behavior in agricultural soils
ABSTRACT Overliming is an effective way of neutralizing and reducing the toxicity of the hydrolysates generated from acidic pretreatment of lignocellulosic biomass for ethanol production and others biotechnological products. Overliming generates a solid residue whose inadequate disposal may represent an environmental problem. This work aimed at the chemical

2. Carbonate-silicate ratio for soil correction and influence on nutrition, biomass production and quality of palisade grass
Silicates can be used as soil correctives, with the advantage of being a source of silicon, a beneficial element to the grasses. However, high concentrations of silicon in the plant would affect the digestibility of the forage. To evaluate the influence of the substitution of the calcium carbonate by calcium silicate on the nutrition, biomass production and

3. 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

4. DESENVOLVIMENTO INICIAL DE SANGUE-DE-DRAGÃO (Croton lechleri MÜLL. ARG.) SOB DIFERENTES CLASSES DE SOLOS, CORRETIVOS E NÍVEIS DE LUMINOSIDADE NA AMAZÔNIA CENTRAL / DESENVOLVIMENTO INICIAL DE SANGUE-DE-DRAGÃO (Croton lechleri MÜLL. ARG.) SOB DIFERENTES CLASSES DE SOLOS, CORRETIVOS E NÍVEIS DE LUMINOSIDADE NA AMAZÔNIA CENTRAL
The specie dragons blood (Croton lechleri) having been calling international attention due the presence of an alkaloid in its latex called taspine known for its antinflammatory, antibiotic and cicatrizing properties, being largely used in the healing of gastric ulcers, diarrhea and different types of viruses. The latex indiscriminated extraction from native

5. 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

6. Distribuição do fósforo no perfil do solo sob sistema plantio direto
The Cerrado, even with soils of low fertility, has been increasing in importance within the Brazilian agricultural scenario, by planning the use and management of land, with the adoption of no-tillage system (NT) and the use of correctives and fertilizers. The application of fertilizers in NT is all doneon the soil surface, which leads to the accumulation of

7. Use of LD steel slag as correctives of the soils acidity to economically expressive crops and evaluation of the environmental risks / Utilização de escória de aciaria como corretivo da acidez de solos para cultivos de soja e cana-de-açúcar e avaliação da contaminação ambiental
O emprego de escórias de siderurgia como fertilizantes e corretivos da acidez de solos tem se mostrado uma alternativa viável para o aproveitamento desses resíduos na agricultura. Entretanto, é necessário considerar a concentração de metais pesados e outros elementos tóxicos nesses materiais, que podem limitar seu uso. Em vista do exposto, este traba

8. Development of a variable rate lime application system. / Desenvolvimento de um sistema de aplicação localizada de calcário a taxas variáveis.
As distribuidoras de calcário convencionais existentes no mercado são projetadas para distribuir o calcário em doses constantes, sem levar em consideração a variabilidade espacial existente no terreno. A presente pesquisa teve como objetivo, projetar e construir um sistema de aplicação localizada de calcário a taxas variáveis. Este sistema, possibil
