Plant growth‐ promoting bacteria inoculation and co‐inoculation effects on Palisade grass (Urochloa brizantha cv. Marandu) in ferralsol in Amazonas State, Brazil

Soil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract Deforestation is primarily driven by three main factors the conversion of the Amazon rainforest into pastureland, agriculture, and mining, as well as land invasion. These pastures are mostly degraded, and it is necessary to restore their productive capacity. Microbial inoculants can be used to increase nutrient use efficiency. The objective of

Managing soil acidity and carbon emission in crop systems

Soil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract Liming is essential for achieving high crop yields in tropical acidic soils, but lime dissolution releases CO2, whereas silicate slag does not, while gypsum improves subsoil fertility. Although the benefits of these amendments for soil fertility are well known, their combined effects on CO2 emissions and soil carbon (C) accumulation in ...

Genotype × Environment Interaction for Leaf Dry Matter Yield in Guineagrass: Identification of Mega‐Environments and Optimization of Multi‐Environment Trials

Grass and Forage Science, Volume 81, Issue 3, July-September 2026.
ABSTRACT Guineagrass (Megathyrsus maximus B.K. Simon & S.W.L. Jacobs [syn. Panicum maximum Jacq.]) presents the highest forage production potential among apomictic cultivated tropical forage grasses in Brazil, and the development of superior cultivars depends on accurate genotype evaluation across multiple environments. This study aimed to characterize

Cover Crops Enhance Aboveground Biomass, Soil Biological Activity and Soil Organic Carbon in Tropical Agroecosystems

Soil Use and Management, Volume 42, Issue 3, July‐September 2026.
ABSTRACT In tropical agroecosystems, soil organic carbon (SOC) accrual is constrained by rapid organic matter turnover and seasonal water limitation. Cover crops are widely used to improve soil C inputs, but their effects on SOC fractions and soil biological activity can vary according to species composition and management duration.

Cover crops and nitrogen rates: Impacts on no‐till corn and soil health in Louisiana

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Use of cover cropping systems to improve soil health is still limited in Louisiana. This study aimed to examine the interaction between cover crops and nitrogen (N) fertilizer rates on crop yield, soil chemical, and biological properties. Winter cover crop treatments, including legumes, a grass and brassica, and a fallow control, were combined

Generalist With a Narrow Niche Breadth: Feeding Ecology and Seed Germination Effectiveness of a Large Canid Within a Silvicultural Matrix

Austral Ecology, Volume 51, Issue 6, June 2026.
Diet: The generalist canid exhibits a narrow niche breadth (0.12), consuming native plants (100% frequency) and animals (85%). Birds dominate animal prey (74%), peaking in the dry season, while Solanaceae plants dominate plant food (100%), peaking in the rainy season.

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 ...
