Soil dynamic alterations and use efficiency of nitrogen by Brachiaria species
(2017-01-01)
Under certain circumstances species of the Brachiaria genus, particularly B. humidicola might be able to suppress the biological nitrification in soil. This study aimed to investigate the ability of four Brachiaria species ...
Emergência de Espécies de Plantas Daninhas do Gênero Brachiaria sob Palha de Cana-de-Açúcar
(2016-07-01)
The objective of this study was to evaluate the effects of soil cover with sugarcane residue on weed emergence of four weeds from the genus Brachiaria. The study was conducted in an area whose soil was classified as Red ...
Soil nitrogen dynamics after Brachiaria desiccation
(Sociedade Brasileira de Ciência do Solo, 2013-12-01)
Brachiaria species, particularly B. humidicola, can synthesize and release compounds from their roots that inhibit nitrification, which can lead to changes in soil nitrogen (N) dynamics, mainly in N-poor soils. This may ...
