Imazaquin sorption in surface and subsurface soil samples.

The objective of this work was to study the sorption and desorption of imazaquin, in surface and subsurface soil samples from Brazil. Sorption and desorption steps were carried out using batch equilibration and high performance liquid chromatography analytical routines. The value of Kf,ads was positively correlated with clay content, and negatively correlated with pH of supernatant. Samples from Typic Haplustox, clayey soil profile having high clay content, provided higher Kf,ads values, and negative correlation with organic carbon, silt content, cation exchange capacity and pH

Agronomic effectiveness of rock phosphates for corrective fertilization of an Oxisol from brazilian savanna cultivated with maize and common beans.

Due to the inherently low content and high degree of phosphorus fixation in the most part of Brazilian Savanna soils, Phosphorus fertilization is essential to attend crop demands. The fully acidulated phosphates are the main sources of Phosphorus used in Brazil, which more than half are imported. The study of the feasibility of using rock phosphates available regionally in Brazil could be an important strategy for reducing the amount of applied soluble phosphates

Interlinking two institutional KOS about agroecology: using LOD Agrovoc to circumvent the language barrier in identifying terminological intersections.

This work describes the methodological approach proposed to resolve the matter of indicating equivalent terms in both languages to the same concept recorded in Agrovoc related to the discipline of Agroecology
