To calculate ammonia emissions caused by production, storage and application of farm
manure, it is necessary to know the amount of farm manure obtained in the country and also the
kinds of manure. For this purpose, methodology and computer software are dev
eloped to calculate
the amount of farm manure based on the data of the Central Statistical Bureau, the technology of
farm animal handling in the country and the respective valid normative documents. Upon
calculating the amount of farm manure produced in La
tvia in 2016, it was stated that
approximately a half of the manure is litter manure, one third
–
liquid manure, and one fifth
–
manure left in the pastures. The most of manure in Latvia (69% of the total amount) is obtained
from milk cows, their calves an
d young stock.
