Effects of eucalyptus thinning on soil chemical attributes in an unfertilized silvopastoral system 6 years after thinning

Soil Science Society of America Journal, Volume 90, Issue 1, January/February 2026.
Abstract Tree thinning is a common practice in silvopastoral systems, but there is no standard percentage of thinning used by farmers. Moreover, it is unclear how the percentage of thinning affects soil chemical attributes throughout the soil profile and throughout the transect between eucalyptus lines.

Levels of nutrients and grain yield of maize intercropped with signalgrass (Brachiaria) in different arrangements of plants [PDF]

Planta Daninha, 2015
Competition between maize and signalgrass can economically cripple the intercropping by the reduced yield of maize and dry matter content of the forage. In seeking to define plant arrangements which make this system more efficient, this research was held

Plant Growth‐Promoting Rhizobacteria Impacting Forage Mass of Urochloa ruziziensis and Megathyrsus maximus: A Reliable New Strategy for Tropical Pastures

Grass and Forage Science, Volume 81, Issue 1, January-March 2026.
ABSTRACT Brazil is known for its extensive livestock production in pastures, supporting the world's second‐largest herd of cattle and being the leading beef exporter. However, livestock farming in Brazil has frequently been associated with soil degradation and greenhouse gas (GHG) emissions.

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.

Genetic Parameters of Resilience Indicators Across Growth in Beef Heifers and Their Associations With Weight, Reproduction, Calf Performance and Pre‐Weaning Survival

Journal of Animal Breeding and Genetics, Volume 143, Issue 1, Page 79-91, January 2026.
ABSTRACT In tropical extensive beef cattle systems, heifers raised on pasture are exposed to various environmental challenges that affect their growth and reproductive performance during the first breeding. Resilience indicators derived from deviations in longitudinal traits can quantify the magnitude of these challenges and the ability of an animal to
