Неприятный запах от сельскохозяйственных животноводческих предприятий доставляет определенные неудобства расположенным поблизости жилым и производственным объектам. Чтобы уменьшить проблему с запахом, в животноводческих помещениях и при хранении навоза могут быть использованы для укрытия различные материалы, включая подстилочные. (Цель исследования) Изучить возможность использования смеси биоугля и торфа в качестве присыпки для навоза, чтобы снизить интенсивность запаха на звероводческих фермах. (Материалы и методы) В лабораторных условиях исследовали свойства смеси биоугля и торфа для нейтрализации запаха. Свежий навоз от норок слоем 10 сантиметров поместили на дно 5-литрового тестового резервуара. Покрыли его смесью биоугля и торфа (в соотношении 50/50 по объему). Использовали 5 вариантов толщины покрытия. Непокрытый смесью навоз приняли за контрольный образец. Интенсивность запаха определяли обонятельным методом. Описали характер запаха. (Результаты и обсуждение) Выявили, что покрытие навоза смесью биоугля и торфа толщиной не менее 3 сантиметров способно значительно уменьшить запах. Характер запаха был сначала торфоподобным во всех покрытых смесью резервуарах, но при тонком покрытии через 2 дня он становился более похожим на запах навоза. Запах от резервуаров с покрытием большей толщины оставался торфоподобным в течение всего периода исследования. (Выводы) Рекомендовали применять присыпку из биоугля и торфа для нейтрализации аммиака и неприятного запаха от навоза на зверофермах. Показали, что частота применения и толщина слоя смеси зависят от температуры окружающей среды, зимой присыпать навоз не требуется.</p></abstract><trans-abstract xml:lang="en"><p>Abstract. Odour from agriculture causes local nuisance to the neighborhood. Litter and cover materials can be used in animal housing and in storage of manure to reduce the odour problem. The use of biochar as a covering for animal manures is a new innovation and enhances the possibility to minimize the emissions from animal farms. (Research purpose) To study the possibility of using a mixture of biochar and peat as a manure covering, in order to reduce the intensity of odor on livestock farms. (Materials and methods) The potential of a mixture of biochar and peat for the odour control was tested in a laboratory study. A 10 cm layer of fresh mink manure was placed on the bottom of a 5 liter test bucket and the manure was covered with biochar-peat mixture (mixed in 50/50 ratio by volume) using five different covering thicknesses. Uncovered manure was used as a reference. The odour emission was measured with an olfactometric method that is based on odour sensation of a person. Also the character of the odour was described. (Results and discussion) The results show that a biochar-peat covering of at least 3 cm is able to considerably reduce the odour from the manure. The character of the odour was at first peat-like for all covered buckets but with thin coverings it was changed to more manure-like after 2 days. The odour from buckets with thicker covers remained peat-like during the whole testing period. (Conclusion) It is recommended to apply a biochar-peat covering to neutralize ammonia and the unpleasant manure odour on livestock farms. The author has shown that the frequency of use and the thickness of a covering layer depend on the ambient temperature; therefore, it is not necessary to cover manure in winter.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>эмиссия</kwd><kwd>нейтрализация неприятного запаха</kwd><kwd>раздражающее воздействие</kwd><kwd>биоуголь</kwd><kwd>торф</kwd><kwd>животноводство</kwd></kwd-group><kwd-group xml:lang="en"><kwd>emission</kwd><kwd>neutralization of unplesant odour</kwd><kwd>annoyance</kwd><kwd>biochar</kwd><kwd>peat</kwd><kwd>animal husbandry</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Lyngbye M., Hansen M.J., Riis A.L., Jensen T.L., and Sørensen G. 1000 Olfactometry Analyses and 100 TD-GC/ MS Analyses to Evaluate Methods for Reducing Odour from Finishing Units in Denmark.
