1. Ácidos orgânicos de baixa massa molar em solos e materiais orgânicos
Determination of organic acids in soils and organic materials is important due to the important role they play in improving the soil's physical, chemical and microbiological conditions. This study identified and quantified low molecular weight organic acids (LMWOA) in soils (dystroferric Red Latosol, dystrophic Red-Yellow Latosol and Quartzarenic Neosol) and

2. Effect of irrigation water salinity and cutting age on the components of biomass of Echinochloa pyramidalis
The objective was to evaluate the effect of salinity of irrigation water and different cutting ages on the biomass components of Echinochloa pyramidalis. Seedlings were planted in plastic pots (volume of 8 L) with sandy-textured Quartzarenic Neosol, under greenhouse conditions. The design was completely randomized in split plots with salinity levels (0.75, 2

3. Efeito da velocidade de escoamento da solução e do comprimento da coluna de solo nos parâmetros de transporte de solutos em solos argiloso e arenoso / Effect of pore water velocity and the length of soil column on solute transportation parameters in clay and sandy soils
The effectiveness of the mathematical models developed to describe the solute transport in the soil depends on the reliability of the values of the transport parameters. Although the determination of these parameters use the same transport equation, some experimental conditions such as the column length and the pore water velocity does not have standards, ma

4. Micronutrientes no solo sob diferentes fitofisionomias no Pantanal da Nhecolândia, Mato Grosso do Sul.
A paisagem do Pantanal é composta por um mosaico de formações vegetais de aspectos diversos, que compreendem campos inundáveis, cerrado, cerradões e florestas. Aliado ao regime de inundação, os solos têm um papel primordial na diferenciação das comunidades vegetais. Este trabalho teve por objetivo avaliar o teor de micronutrientes no solo, nas cama

5. CaracterizaÃÃo hidrodispersiva de dois solos da regiÃo irrigada do Vale do SÃo Francisco / Characterization hidrodispersive of two soils of the irrigated region of the valley of the San Francisco
The hydrodispersive characterization of a Latosol and a Quartzarenic Neosol, both from the irrigated region of the SÃo Francisco Valley, was carried out in laboratory by means of assays of displacement of miscible liquids in columns of deformed soil. The assays were based on the displacement of a pulse of an amount of KBr equivalent to the volume of pores i

6. Soil quality of cultivated and native pastures systems in the Nhecolandia sub-region, South Pantanal Wetlands. / Qualidade do solo em sistemas de pastagens cultivada e nativa na sub-regiÃo da NhecolÃndia, Pantanal Sul Mato-Grossense
The Pantanal is one of the planetâs largest continuous wetlands areas and where fauna and flora of outstanding beauty and abundance develops. Favored by the richness of natural resources, beef cattle raising, conducted in extensive raising systems, constitutes the chief economic activity. However, the search for yield increases and greater competitivity of

7. Resposta de cultivares de arroz de terras altas (Oryza sativa L.) ao silÃcio / Upland rice (Oryza sativa L.) cultivars response to silicon
Many factors contribute for rice culture low yield some of them related to mineral ntrition Eventhoug silicon (Si) has not been considered essential physiological yet its uptable brings a host of beneficts to rice culture thus showing its âagronomic essencialityâ for sustenable production and improved yield Simultaneously its necessary to study cultivars r

8. Retention and degradation of 14C-glyphosate and remobilization of its bound residues in two tropical soils / Retenção e degradação de 14C-glifosato e remobilização dos seus resíduos ligados em diferentes classes de solos
O glifosato é um dos herbicidas mais consumidos no Brasil e com perspectivas de aumento deste consumo, diante da expansão do plantio direto e do plantio de culturas geneticamente modificadas com resistência a esse herbicida. Porém, pesquisas com esta molécula são ainda incipientes em solos de clima tropical. Nesse contexto, esta pesquisa objetivou gera
