The aim of the research is to determine emitted greenhouse gases (GHG) and ammonia emission distinction between two fertilizers types: ammonia nitrate and carbamide (urea). One of the most fertile soils in Latvia are located in Zemgale Region and it is used in research. Samples of tilled soil are used for the research according to the conditions of soil. One of influential factors of the GHG emissions is soil moisture, because humidity in combination with temperature controls the activity of microorganisms and other related processes that is crucial to determine the gases from the soil. Measurements were carried out with an average of one second temporal measurement scale using a mobile cavity ring-down spectrometer Picarro G2508, which takes a measurements of N2O, CH4, CO2, NH3, and H2O simultaneously. The evaluation of impact was made using measurement matrix with six variations of soil moisture and fertilizer dose and emitted gasses are acquired in a certain time period. The results showed that the highest concentration of nitrous oxide were on the second measuring day at higher moisture quantity, while, the concentrations of emitted ammonia were immediately after the fertilizer and water entered the soil. The results of research is crucial to improve inventory of gaseous emissions and can lead to right abatement strategy for specific soil type.
