At the same time the nitrogen air emission ( 15,850 tons) was only 89% of the average of the past 22 years and the lowest in this period, thus the net nitrogen budget (17,508 tons) was 7% higher than the average of the last 22 years.
Hkrati je bila količina emisije dušika v zrak v letu 2013 le 89 % povprečja zadnjih 22 let (15.850 ton) in sploh najmanjša v tem obdobju, tako da je bila neto zaloga dušika v tleh (17.508 ton) kar za 7 % večja od povprečja zadnjih 22 let.
