Subsoil Carbon and δ13C Spatial Patterns Reveal Land Use Legacy in a Sandy Subtropical Ecotone in Brazil

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract Soil organic carbon (SOC) storage represents one of the most critical ecosystem services provided by soils, yet scientific assessments frequently focus on surface layers, overlooking deeper horizons. In this study, we investigated SOC stocks and spatial patterns of soil δ13C across three contrasting land use and land cover (LULC) types in ...

Protodioscin levels in Brachiaria spp. in a sheep production system and a brief review of the literature of Brachiaria spp. poisoning in ruminants

Pesquisa Veterinária Brasileira, 2021
: Plants of the genus Brachiaria, used in several countries as forage, are poisonous to some livestock species. Their toxic principle is protodioscin, and the main form of clinical presentation of the toxicosis is hepatogenous photosensitization. Here we

Repeatability, Genetic Variability and Importance of Forage Traits in Ecotypes of Brunswickgrass (Paspalum nicorae Parodi) via BLUP

Plant Breeding, Volume 145, Issue 3, Page 561-574, June 2026.
ABSTRACT This study estimated the repeatability of forage traits in 84 Paspalum nicorae ecotypes using six statistical methods and quantified the minimum number of harvests needed for effective selection. Multivariate analyses based on best linear unbiased prediction (BLUP) values were also performed to assess genetic variability, identify key traits ...

Brachiaria decumbens supresses the initial growth of Coffea arabica [PDF]

Scientia Agricola, 2004
Brachiaria decumbens is becoming one the most common weeds growing in young coffee orchards because, besides its fast growth and difficulty of control, new coffee orchards are usually established in pasture areas. In order to verify the effect of B. decumbens plant density on the early growth of coffee (Coffea arabica L. cv.

Response of cereals to intercropping with non‐food crops in tropical and subtropical regions: A meta‐analysis

Agronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Intercropping cereals with non‐food intercrops (NFICs) provides a means to enhance cereal productivity while providing additional benefits such as improved soil health or forage production. We conducted a meta‐analysis to investigate the effect of NFICs on cereal yields, cereal nitrogen uptake, and striga (Striga spp.) infestation, using 874 ...
