Ammonia volatilization from nitrogen fertilizer formulated with biochar. Repositório Alice
PUGA, A. P.; CARVALHO, C. S.; LIGO, M. A. V.; PIRES, A. M. M.; PEREIRA NETO, B. G.; ANDRADE, C. A. de.
Ammonia (NH3) volatilization results in low N use efficiency by crops. The aim of this study were to evaluate NH3 volatilization from nitrogen fertilizer formulated (F) with biochar (BC). In a incubation experiment the fertilizers were applied to soil surface. NH3 volatilized was captured by H2SO4 solution. BC used in the production of fertilizers is from eucalyptus (charcoal fines). Two types of formulated fertilizers were tested: granulated (F6 and F8; mixture of BC, urea and additives) and coated granulated fertilizers (F17 and F19; coating of urea granule with BC, acidified or not, and additives). Treatments tested were: 1) blank; 2) control; 3) soil + urea; 4) soil + F6 (10% N, 51% BC); 5) soil + F8 (20% N, 29% BC); 6) soil + F17 (20% N, 29% BC) and...

Al; Organic Plant Production and Agroecosystems Research in the Tropics and Subtropics, University of Kassel, Witzenhausen, Germany; Gebauer, Jens.
Little is known about gaseous carbon (C) and nitrogen (N) emissions from traditional terrace agriculture in irrigated high mountain agroecosystems of the subtropics. In an effort towards filling this knowledge gap measurements of carbon dioxide (CO_2), methane (CH_4), ammonia (NH_3) and dinitrous oxide (N_2O) were taken with a mobile photoacoustic infrared multi-gas monitor on manure-filled PE-fibre storage bags and on flood-irrigated untilled and tilled fields in three mountain oases of the northen Omani Al Jabal al Akhdar mountains. During typical 9-11 day irrigation cycles of March, August and September 2006 soil volumetric moisture contents of fields dominated by fodder wheat, barley, oats and pomegranate ranged from 46-23%. While manure incorporation...
