Recording available : Manure Management Webinar – Methods to calculate methane emission from stored liquid manure
Manure management on livestock farms contributes significantly to the climate impact of agriculture via emissions of methane, nitrous oxide and ammonia. The IPCC tier 2 method to estimate methane emissions, developed in 1996, is based on the maximal methane production rate of fresh excreta (B0) and a conversion factor MCF to account for storage conditions. This calculation concept was meant to be simple, because it should be applicable worldwide, including regions where the staff carrying out the calculations has limited information about manure management systems or expertise in how management and environmental conditions may affect the processes behind methane emissions. Three researchers with much experience in developing models to calculate methane emissions from livestock farming will present new improvements of the tier 2 method as well as alternative approaches for calculating the emission. The intention of the webinar is to stimulate new initiatives to investigate the calculation of methane emissions from manure management, with the aim to develop a new generation of methods.
