This study investigated the effects of different mixing ratios of crop residues and biochar with liquid digestate from anaerobically treated pig manure on CH4, CO2, and N2O emissions over 84 days in a system of passive aeration composting, resembling typical Vietnamese solid manure storage conditions. Greenhouse gas emissions from agriculture have increased by 10.1% since 1990. Drivers for this increase include a 7% increase in N2O from management of soils, along with a 58.7% growth in combined CH4 and N2O emissions from livestock manure management systems, reflecting the increased use of emission-intensive liquid systems over this time period. NH3 emissions from livestock manure in the Netherlands dropped by two thirds since 1990, mainly as aresult of lower nitrogen excretion rates by livestock and low emission manure application. Emissions of N2O and NO alsodecreased over the same period, but less strongly (38% and 31% respectively), due to higher emissions from manure injectioninto Direct N as N2O emission factor = 5.000E-03 g / g: Reference: USEPA (2013).

More than 80% of pulses produced in Sweden in 2019 were used for animal feed Estimated emissions of nitrous oxide (N2O) included both direct and indirect emissions. No methane emissions were accounted for, as they were considered and manure to common bean crops further increased the GHG emissions and greenhouse gas emissions than meat and other animal products, and Include CO2, CH4, N2O, HFC, PFC, SF6 and NF3.

This study quantified spatiotemporal patterns of CH4 and N2O emissions from livestock and poultry production in Turkey between 1961 and 2007. CH4(enteric) (from enteric fermentation), CH4(manure) Unfortunately, livestock urine and manure are significant sources of greenhouse gases methane (CH4), nitrous oxide (N2O) when broken down under anaerobic conditions. The improper management of livestock manure not only wastes resources but also leads to agricultural non-point pollution due to the rich organic content and high levels of nutrients.

Seasonal amount of CH4 emission from the treatments of CF + CM, CF + RC and CF + WS was respectively 45%, 252% and 250% higher than that from the treatment of CF, but the application of pig manure (CF + PM) did not significantly influence the CH4 emission. The N2O emissions, on the other hand, were reduced by 18%, 21% and 18% for the treatments About one third of the NH3 emissions from the anaerobically stacked farmyard manure occurred after spreading. Total N losses were at a low level with both storage systems. Greenhouse gas emissions (N2O and CH4) were much higher from the anaerobically stacked farmyard manure than from the composted one. As these are ecologically harmful gases, they have to be considered when judging the form of manure treatment.
