Methane Emissions of a Western Dairy Manure Storage Basin and Their Correlation with Hydrogen Sulfide Emissions

Atmosphere, 2023
Anaerobic decomposition in manure storage contributes to hydrogen sulfide (H2S) and methane (CH4) emissions. Coincident emission measurements were made of these gases from a western free stall dairy manure storage basin over a two-month period (August ...

Ácidos orgânicos na solução de um gleissolo sob diferentes sistemas de cultivo com arroz irrigado Organic acids in the soil solution of a gley soil cropped with lowland rice under different systems

Revista Brasileira de Ciência do Solo, 2005
O alagamento do solo para o cultivo do arroz irrigado promove condições anaeróbias que favorecem a produção de ácidos orgânicos de cadeia curta, os quais podem ser tóxicos para a cultura.

Determination of aerobic and anaerobic biological degradability of waste tyres

Environmental Sciences Europe, 2023
Environmental contamination of rubber from waste tyres poses a risk to the environment. Rubber particles from tyres enter the environment due to the abrasiveness of the road surface.

Anaerobic Decomposition of Activated Sludge

Japanese Journal of Water Treatment Biology, 1983
The anaerobic decomposition of sludge wasinvestigated. With the decrease of ORP, pH increased and MLSS decreased. BOD value ofsupernatant was larger than COD value, butthe ratio of both values was not constant. Acetic and propionic acids were detected in alarge amount as volatile organic acids, and the ratio of volatile acids to BOD values was not ...

Toxidez por ácido acético em arroz sob diferentes valores de pH da solução nutritiva Acetic acid toxicity in rice under different pH values of nutritional solution

Ciência Rural, 2008
A proporção das formas associadas e dissociadas do ácido acético é dependente do pH. O aumento do pH favorece a dissociação do ácido acético, o que pode diminuir seu efeito tóxico para o arroz, pois moléculas com carga são menos solúveis nos componentes ...

SURFACE TEMPERATURE OF THE EXPOSED SILO FACE AS QUICK INDICATOR OF THE DECOMPOSITION PROCESS OF MAIZE SILAGE [PDF]

Journal of Central European Agriculture, 2015
Silage temperature and oxygen concentration are critical parameters for controlling the silage process. Anaerobic condition with lower and stable temperature is necessary for quality silage making.

Toxidez pelos ácidos propiônico e butírico em plântulas de arroz Toxicity of propionic and butyric acids in rice seedlings

Ciência Rural, 2007
A decomposição anaeróbia da matéria orgânica em solos alagados produz ácidos orgânicos de cadeia curta que podem ser tóxicos para o arroz. Com o objetivo de avaliar o efeito de diferentes concentrações dos ácidos propiônico e butírico, em solução ...
