Long-term lime and gypsum amendment increase nitrogen fixation and decrease nitrification and denitrification gene abundances in the rhizosphere and soil in a tropical no-till intercropping system
(2020-10-01)
Liming is widely used to decrease soil acidity, and the application of lime alone or in combination with other amendments, such as gypsum, is a viable agricultural practice to improve soil nutrient status and crop yield. ...
Bioaumentação em reatores anaeróbio e aeróbio e uso de reator nitrificante para redução da carga orgânica e nitrogenada
(Universidade Federal de Santa MariaBREngenharia de ProcessosUFSMPrograma de Pós-Graduação em Engenharia de Processos, 2012-01-13)
Agro-industrial effluents are capable of causing great impact on water bodies if released without adequate treatment. The removal of the organic load in the conventional biological treatments is achieved with high generation ...
