Use of biochar and hydrochar to reduce ammonia emissions from soils fertilized with pig slurry

Year: 2013

Type: conference-paper

Abstract: Ammonia (NH 3 ) volatilization caused by animal manure application to agricultural soils leads to high amounts of nitrogen (N) losses.The use of biochar and hydrochar by-products as soil amendments modifies the dynamic of N in soil and may also influence NH 3 emissions and nitrates leaching.The present study assessed the potential NH 3 emissions after surface application of pig slurry on soils amended with a biochar (from pyrolysis) and an hydrochar (from hydrothermal carbonization) of Miscanthus sp. in a laboratory experiment.The experiment was carried out in a dynamic chambers coupled with a photo-acoustic trace gas analyzer in a controlled environment for 48 hours.Statistical results showed significant differences among treatments.Total emissions of NH 3 and total inorganic N concentrations in the soil extracts were related to type of soil amendment and not to soil type.
