Biogas and Methane Yield from Rye Grass

Biogas production from boreal herbaceous grasses--specific methane yield and methane yield per hectare.

The objective of this study was to determine the specific methane yields of four grass species (cocksfoot, tall fescue, reed canary grass and timothy) cultivated under boreal conditions as well as how harvesting time and year of cultivation affects the specific methane yields per ha. The specific methane yields of all grasses and all harvests varied from 253 to 394 Nl CH4/kg volatile solids (VS...

Isolation of octopamine from annual rye grass.

The Potential for Biogas Production from Grass

Grass is generally considered as one of the major agricultural products and covers over 90% of Irish agricultural land. While useful as an animal feedstock it can also be used for energy production. Here batch mesophilic anaerobic digestion of grass silage was studied. The methane concentration in the biogas clearly showed that grass silage has a high affinity to produce a high quality methane ...

Biogas Production from Chinese Herb-extraction Residues: Influence of Biomass Composition on Methane Yield

The Chinese traditional medicine industry is developing quickly in China, and there is a growing demand for the reasonable treatment of Chinese herb-extraction residues (CHER) that are generated during the process of preparing such medicines. Different from other biomass materials, the nutrient composition of CHER discharged from different producers may vary widely, which makes the study of CHE...

Corn yield and fertilizer N recovery in water-table-controlled corn–rye-grass systems

Concern about NO− 3 leaching and groundwater pollution from corn monoculture has prompted an investigation of alternative production systems that reduce leaching. It is hypothesized that both intercropping and water-table control could increase N uptake and reduce the quantity of N that might be lost due to leaching. This study compared corn (Zea mays L.) with annual Italian rye-grass (Lolium m...
