THE AMMONIA EMMISION REDUCTION EFFECT OF ACIDIFICATION OF PIG SLURRY APPLIED ON WINTER WHEAT
Abstract
Agriculture is the main source of ammonia emissions. It generates around 75% of global emissions of ammonia to the atmosphere and soil manure accounts for half of agricultural emissions. Ammonia emissions have a negative impact on ecosystems and human health, as it is able to accumulate both as solid particles and as an integral part of acid cases. Measures to reduce ammonia emissions can be divided into three large groups: the first group is ammonia-reducing measures in animal housing, the second group is ammonia-reducing measures during manure storage, and the third group is ammonia-reducing measures during the incorporation of manure in soil. Measurements of ammonia emissions were carried out in the parish of Ile, which took place on 16 May and 17 May 2018. Sulphuric acid were used for acidification of pig slurry. Picarro G2508 used for on field measurement of ammonia concentrations with 1 second interval, a measurement time of one session were 400 seconds. The volume of the chamber is 60 l connected to Picarro G2508 using a 10 m long Teflon tube. The measurement of ammonia emissions was with three repetitions for each measurement, with a reference error of less than 5%. Emissions were measured at different time intervals: immediately after pig slurry distribution, and the 24 hours after pig slurry application.
