1. Tembotrione Half-Life in Soils with Different Attributes
RESUMO: Antes de fazer a recomendação de um herbicida, é preciso conhecer suas interações com os atributos do solo que irão influenciar a sua sorção e a meia-vida no solo. Esse conhecimento é condição essencial para serem minimizados os eventuais efeitos negativos que possam resultar de sua aplicação. Todavia, devido à grande diversidade de sol

2. TRANSITION FROM SYSTEMATIC TO DIRECTED SOIL SAMPLING DESIGNS IN AN AREA MANAGED WITH PRECISION AGRICULTURE
ABSTRACT In agricultural areas with a historical of systematic soil sampling, alternative methodologies such as directed sampling design based on management zones (MZ) have been proposed to reduce sampling costs. The aim of this study was to evaluate the technical and economic impacts of replacing a dense systematic soil sampling design (cell size of 0.5 ha)

3. Water retention curve to analyze soil structure changes due to liming
Abstract: Liming can influence crop growth by altering pore geometry, pore size distribution and water retention characteristics in acid soils. The aim of this work is to determine liming effects on the soil structure based on analysis of water retention data using a cubic spline adjustment function. For that, the authors investigated the effect of three lim

4. Liming on picloram leaching in dystrophic Red Yellow Latosol
RESUMO A prática da calagem pode influenciar a lixiviação de herbicidas nos solos, especialmente os com caráter ácido fraco, como é o caso do picloram. O estudo da lixiviação mantendo-se a estrutura do solo é um fator importante quando se busca compreender a dinâmica de herbicidas e possíveis impactos ambientais. Assim, objetivou-se avaliar o efei

5. Biogenic, sedimentary, and metamorphic limestone: a comparative characterization of soil amendment
RESUMO A correção da acidez é fundamental para a atividade agrícola em solos ácidos, assim como a caracterização e estudo do efeito no solo de fontes alternativas de corretivos. Objetivou-se caracterizar os calcários de origem biológica, sedimentar e metamórfica. Os calcários estudados foram: biogênico (CB), sedimentar (CS), comercial (CC) e o m�

6. Chemical Species and Aluminum Concentration in the Solution of Acid Soils Cultivated with Soybean and Corn under Liming
ABSTRACT Chemical speciation of the soil solution is an important tool to identify Al species related to phytotoxicity. In some Brazilian acid soils, the Al extractable by the KCl 1.0 mol L -1 solution (Al-KCl) exceeds 10 cmol c kg -1 and even then, in some situations, it does not cause toxicity to the plants. This study aimed to evaluate the relationship be

7. 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

8. Soil Fertility and Electrical Conductivity Affected by Organic Waste Rates and Nutrient Inputs
ABSTRACT The composition of organic waste (OW) and its effect on soil processes may change soil fertility and electrical conductivity (EC). The side effects of waste use in crop fertilization are poorly understood for Brazilian soils. This study examined the effect of the addition of 15 different organic wastes to Oxisols and a Neosol on pH, base saturation,

9. Effectiveness of Five Biosolids as Nitrogen Sources to Produce Single and Cumulative Ryegrass Harvests in Two Australian Soils
ABSTRACT Biosolids have been produced by various stabilization processes of sewage sludge, but little attention has been given to the effects of such treatments on their effectiveness to supply nitrogen for plant growth. Here, we investigated these effects by cultivating Lolium perenne (ryegrass) in two Australian soils, a sandy Spodosol and a clayey Oxisol.

10. Minjingu phosphate rock availability in low-pH highly weathered soil as affected by added salts
Concentrations and identity of ions in the soil solution may affect soil phosphorus (P) reactions and P availability. In this study, the magnitude of these reactions was evaluated following the application of Minjingu phosphate rock (MPR) combined with chloride and carbonate salts of Na and Ca within an incubation experiment. Twenty-one days later NaOH-P and

11. Fitoextração em solo contaminado com metais pesados / Phytoextraction of soil contaminated with heavy metals
The industrial and urban progress associated with increased production of consumer goods has resulted in the generation of waste, which, for a long time, was indiscriminately discarded in the environment, causing damage usually irreversible to recover. Two experiments were conducted in soils contaminated with heavy metals: the first aimed at the disposal of

12. Vegetative development corn in function of liming and phosphate fertilization / Desenvolvimento vegetativo do milho em função da calagem e adubação fosfatada
O trabalho teve por objetivo determinar a melhor interação entre saturação por bases (V%) e adubação fosfatada na implantação da cultura do milho no Oeste Paulista em solos arenosos. O estudo foi conduzido em Casa-de-Vegetação, em vasos, na Faculdade de Agronomia da Universidade do Oeste Paulista, UNOESTE, durante os meses de setembro de 2009 a jan
