Soil carbon stock and physical attributes under land‐use chronosequence in the Brazilian Cerrado

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Land‐use changes impact soil physical quality and carbon stocks. Most studies evaluating the conversion of native Brazilian Cerrado to agriculture focus on surface soil layers (up to 40 cm), with fewer examining deeper layers (0–100 cm). This study assessed the impacts of different land‐use systems on soil physical attributes and soil organic ...

Desiccation Periods of Urochloa brizantha ‘Piatã’ Before Sunflower Sowing

Journal of Agricultural Science, 2013
In no-till farming, which integrates crops and livestock, the crop that is sown is often noted for reduced productivity. The aim of this experiment was to study the influence of a desiccation period of Urochloa brizantha ‘Piata’ on sunflower ‘Aguara 4’ development and productivity.

A role for phytosiderophores by Poaceae to acquire phosphorus in severely phosphorus‐impoverished habitats

Journal of Ecology, Volume 114, Issue 8, August 2026.
This study demonstrates that several native grasses employed phytosiderophores not only for Fe acquisition, but probably also to mobilise P in their natural severely P‐impoverished habitats, supported by concomitant carboxylate exudation. These findings expand our understanding of integrated P‐acquisition mechanisms in Poaceae within nutrient‐limited ...

Response of Urochloa brizantha cv. BRS Piatã to different levels of aluminum and to silicon application

Interference
The aim of the present study was to evaluate the response of the forage Urochloa brizantha cv. BRS Piatã to different levels of aluminum (Al) and the use of silicon (Si) as an attenuator of Al toxicity. For this, plants of U. brizantha were cultivated in
