Forage Grasses Steer Soil Nitrogen Processes, Microbial Populations, and Microbiome Composition in A Long-term Tropical Agriculture System
(2022-01-01)
Forage grasses used in cropping no-till systems in tropical regions alter soil chemical properties, but their long-term impact on soil microbial processes of the nitrogen (N) cycle and microbial community abundance, ...
Forage accumulation in brachiaria grass under continuous grazing with single or variable height during the seasons of the year
(Revista Brasileira de Zootecnia, 2017)
Species-specific trade-offs between regrowth and mycorrhizas in the face of defoliation and phosphorus addition
(Elsevier, 2021-06)
Arbuscular mycorrhizal fungi (AMF) enhance nutrient provision in exchange for carbon. However, a shift from nutrient to carbon limitation, induced by repeated or intense defoliation, can represent a trade-off between plant ...
Separação de competição e alelopatia em associações entre capim-annoni-2 (Eragrostis plana) e braquiária (Brachiaria brizantha cv. Marandu) em cultivo hidropônico
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de Ciências AgráriasAgronomiaUTFPR, 2018-06-12)
The capim-annoni-2 (Eragrostis plana Nees), is an exotic grassland that represents a great threat to brazilian ranchers, due to its high competitive capacity and liberation of allelochemicals. In the field, the competitive ...
