Closing nutrient loops in a maize rotation. Catch crops to reduce nutrient leaching and increase biogas production by anaerobic co-digestion with dairy manure
نویسندگان
چکیده
Three catch crop species, ryegrass, forage rape and black oat, were grown between successive rotations of maize to reduce nitrogen leaching due fertilization with digested dairy manure. Catch crops showed a high nutrient uptake, but wide range, depending on the year specie. Ensiling was shown be feasible storing method increasing methane production per hectare 14–36% compared fresh crop. In semi-continuous co-digestion experiments, increased 35–48%, in comparison anaerobic digestion manure alone. good co-substrate, being sustainable option prevent nutrients environment, thus closing loops from utilization by optimal recycling measures.

Anaerobic Co-digestion of Dairy Manure with Potato Waste
In this study, anaerobic co-digestion of dairy manure (DM) and potato waste (PW) was evaluated to determine the best mixing ratio in terms of biogas and methane (CH4) productions. Batch lab-scale anaerobic co-digestion of DM with PW was conducted at two different temperature ranges [mesophilic (MT) (35-37 oC) and thermophilic (TT) (55-57 oC)]. The tests were conducted at five DM:PW mixing ratio...

Effect of Physical and Chemical Operating Parameters on Anaerobic Digestion of Manure and Biogas Production: A Review
Introduction: The need for food produced from animal husbandry has made it a growing industry which result in increment of livestock waste. On the basis of environmental and economic considerations, these materials require treatment and management. Anaerobic digestion and creation of biogas are the most effective methods of waste management. Several parameters affect the anaerobic digestion of ...
متن کامل2. Production of Biogas by Anaerobic Digestion
Anaerobic digestion is a natural process in which bacteria convert organic materials into biogas. It occurs in marshes and wetlands, and in the digestive tract of ruminants. The bacteria are also active in landfills where they are the principal process degrading landfilled food wastes and other biomass. Biogas can be collected and used as a potential energy resource. The process occurs in an an...
