Soil dynamic alterations and use efficiency of nitrogen by Brachiaria species
(Australian Journal of Crop Science, 2017-01-01) [Artigo]
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 ...
Soil nitrogen dynamics after Brachiaria desiccation
(Revista Brasileira de Ciência do Solo, 2013-12-01) [Artigo]
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 ...
Soil phosphorus availability and soybean response to phosphorus starter fertilizer
(Revista Brasileira de Ciência do Solo, 2014-10-01) [Artigo]
Phosphorus fixation in tropical soils may decrease under no-till. In this case, P fertilizer could be surface-spread, which would improve farm operations by decreasing the time spend in reloading the planter with fertilizers. ...
Ruzigrass affecting soil-phosphorus availability
(Pesquisa Agropecuária Brasileira, 2013-12-01) [Artigo]
The objective of this work was to evaluate the effectiveness of ruzigrass (Urochloaruziziensis) in enhancing soil-P availability in areas fertilized with soluble or reactive rock phosphates. The area had been cropped for ...
Nitrogen immobilization by Congo grass roots impairs cotton initial growth
(Journal of Agricultural Science, 2012) [Artigo]
In crop-livestock integration systems the presence of both grass roots in the soil and straw on the surface can temporarily immobilize nitrogen. This study examined the persistence of grass residues in the system as well ...
