Nitrogen fertilizer effect in production, nutrient accumulation and nitrogen efficiency use of second ratoon sugarcane harvested without straw burning
(2017-05-01)
Sugarcane harvest after straw burning implies rapid mineralization of biomass and greenhouse gas emissions. In this context, maintenance of sugarcane straw on the soil is as a new strategy to circumvent the harmful ...
Atmospheric concentrations and dry deposition of reactive nitrogen in the state of São Paulo, Brazil
(2020-06-01)
Estimates of nitrogen deposition play a key role in better understanding the human impacts on the nitrogen biogeochemical cycle. This paper examines the concentration of reactive nitrogen (Nr) in the atmosphere and the ...
Measurements and modeling of reactive nitrogen deposition in southeast Brazil
(2011)
Increased reactive nitrogen (Nr) deposition due to expansion of agro-industry was investigated considering emission sources, atmospheric transport and chemical reactions. Measurements of the main inorganic nitrogen species ...
Increases in nitrogen use efficiency decrease nitrous oxide emissions but can penalize yield in sugarcane
(Springer Verlag Berlín, 2021-11-30)
Nitrogen (N) fertilization strategies focused on increasing nitrogen use efficiency (NUE) and decreasing nitrous oxide (N2O) emissions are important for sustainable crop production. In sugarcane, however, a joint assessment ...
PECVD of amorphous hydrogenated oxygenated nitrogenated carbon films

Increases in nitrogen use efficiency decrease nitrous oxide emissions but can penalize yield in sugarcane
(Springer, 2021-11)
Nitrogen (N) fertilization strategies focused on increasing nitrogen use efficiency (NUE) and decreasing nitrous oxide (N2O) emissions are important for sustainable crop production. In sugarcane, however, a joint assessment ...
Greenhouse gases emissions from tropical grasslands affected by nitrogen fertilizer management
(2020-11-01)
Greenhouse gases (GHGs) emissions from livestock systems are important because of their significant contribution to global warming. Nitrogen fertilization can improve system production; however, it alters soil gas emissions. ...
Seasonal effects on ammonia, nitrous oxide, and methane emissions for beef cattle excreta and urea fertilizer applied to a tropical pasture
(2019-11-01)
In this study we conducted four field trials (two wet- and two dry-season) to quantify N2O and CH4 emissions, NH3 volatilization, and N2O emission factors (EF3PRP) following the application of cattle dung, urine, dung plus ...
Avaliação de NO2 na atmosfera de ambientes externos e internos na cidade de Araraquara, São Paulo
(Sociedade Brasileira de Química, 2009-01-01)
The seasonal behavior of NO2 concentration shows a maximum occurring during sugarcane crop and this suggests that the biomass burning is significant source of emission at this time of the year. Along the day, the variation ...
