Soil inorganic nitrogen content according to cover crops, nitrogen sources and nitrification inhibitor

Pesquisa Agropecuária Tropical, 2013
The use of cover crops can change the soil NO3-: NH4+ ratio, providing larger amounts of NH4+, and enable the development of crops which absorb more or prefer this form of nitrogen (N), like rice.

Soybean growth and production under straw of maize, Urochloa brizantha, Conyza spp. and Digitaria insularis

Plant Science Today, 2022
Weeds can cause serious damage during soybean development, due to allelopathy, competition for water, light and nutrients. It is necessary to investigate the influence of straw, of weeds Conyza spp. and Digitaria insularis, in soybean growth, production and composition and grains. If there is influence of allelopathic compounds at the crop.

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

Agronomic responses and botanical composition of warm‐season annual forages managed under contrasting harvest strategies

Crop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.
Abstract Warm‐season annual (WSA) forages enhance the summer forage supply in subtropical livestock systems. The objective of this study was to determine forage mass (FM), nutritive value, nitrogen (N) yield, and botanical composition in 12 forage mixtures managed under two harvest strategies (simulated grazing vs. baleage). A randomized complete block

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 ...

Coexistence of soybean plants and Urochloa spp. under glyphosate and water deficit effects

Científica, 2019
In the insertion of forage plants of the genus Urochloa P. Beauv. (Poaceae) coexisting with annual crops, proper management of the intercropping becomes necessary to avoid economic losses. Among management measures, the chemical inhibition of forage plants with herbicide subdoses is highlighted.

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.
