Late Stages of Tropical Silvopastoral System: An Opportunity to Maximise Forage and Animal Production

Grass and Forage Science, Volume 80, Issue 3, July-September 2025.
ABSTRACT Silvopastoral systems (SPS) integrate pasture, trees, and animals in the same area and are alternatives for sustainable pasture intensification. We aimed to test whether, in the late stages of an SPS, with large but sparsely distributed trees (83 trees ha−1), forage and animal productivity are comparable to a full sun pasture (FS) over an ...

Land‐Use Change Enhances Organic Phosphorus Pools in Oxisols in Brazil's New Agricultural Frontier

Soil Use and Management, Volume 41, Issue 3, July‐September 2025.
ABSTRACT Land‐use types and management systems can affect the availability of phosphorus (P) by modifying its compartments. The aim of this study was to evaluate the organic and inorganic fractions of P in an Oxisol in the Cerrado region of Brazil, considering various land‐use types and management systems and the period of application.

Sewage sludge-based organomineral fertilizer improves phosphorus efficiency in Urochloa brizantha

Revista Brasileira de Ciência do Solo
ABSTRACT Sewage sludge (SS) from wastewater treatment has reasonable phosphorus (P) levels, which could be used as fertilizer in agriculture. However, SS-P content is lower than mineral fertilizers, which limits its operational application.

Structural and productive responses of signalgrass and its association with leaf area index and light interception under silvopastoral or monoculture systems

Agrosystems, Geosciences &Environment, Volume 8, Issue 2, June 2025.
Abstract Silvopastoral systems (SPSs) have emerged as one of the most prominent alternatives for grassland recovery. We evaluated the structural and productive responses of signalgrass [Urochloa decumbens (Stapf.) R. D. Webster] and its association with leaf area index (LAI) and light interception (LI) measured with different equipment across different
