In the Amazon region, there is no information on the fertilization of banana plants with boron (B). Besides this, the extractant (hot water) currently used to test B concentrations has many limitations. The aim of this work was to study the effect of B on the fruit yield and quality of banana plants of the Cavendish (AAA) sub-group, grown in dystrophic Yellow Latosol (Oxisol or Xanthic Ferralso...

We conducted a greenhouse experiment in mesocosms for 28 days to assess the effects of endogeic earthworm Pontoscolex corethrurus on plant-available soil phosphorus (P) and rice (Oryza sativa) P nutrition Malagasy Ferralsol. To P, we determined L-value by measuring specific activity taken up from applying isotopic dilution principle. Despite mortality, P. significantly increased shoot biomass (...

In no-tillage systems, soil compaction has caused negative impacts on crop productivity and quality. The objective of this study was to evaluate the physical quality after different crops second season: maize, sorghum, millet in compacted uncompacted soils, addition evaluating performance soybean succession Rhodic Ferralsol under (NT) Brazilian Cerrado biome. A field experiment conducted during...

Saflufenacil is a herbicide recommended for use in the main agricultural crops Brazil to control eudicotyledonous weeds. However, application of saflufenacil has been carried out without previous knowledge this interactions with soil colloids, which may increase environmental contamination risks. In study, leaching samples was estimated different organic matter contents. Therefore, PVC columns ...
