How can process-based modeling improve peat CO2 and N2O emission factors for oil palm plantations? por Swails, E., Hergoualc'h, Kristell, Deng, J., Frolking, S., Novita, N.

“…The modeled N2O-N EF from peat decomposition was higher than the IPCC default (1.2 kg N ha−1 yr−1) and increased from 3.5 ± 0.3 kg N ha−1 yr−1 in the first decade to 4.7–4.6 ± 0.5 kg N ha−1 yr−1 in the following ones. …”

Características físicas del huevo incubable y pollitos nacidos de reproductores pesados cobb 500 en incubadoras con diferente humedad relativa por Yuño, M.M., Bakker, María L., Cepeda, Rosana, Marinelli, C., Malacalza, F.

“…En las tres incubadoras, la edad de los reproductores tuvo una relación lineal positiva (p<0,05) con H pero una relación lineal negativa (p<0,05) con N. Se observó que H tuvo una relación lineal negativa (p<0,05) con C solamente en las incubadoras de 51,3% y 56,5% de HR, indicando que H tendría una relación con C menos relevante en las incubadoras de mayor HR. …”

Postfire nitrogen balance of Mediterranean shrublands: Direct combustion losses versus gaseous and leaching losses from the postfire soil mineral nitrogen flush por Dannenmann, Michael, Díaz Pinés, Eugenio, Kitzler, B., Karhu, K., Tejedor, J., Ambus, P., Parra, A., Sánchez Martin, L., Resco, V., Ramírez, D., Povoas-Guimaraes, L., Willibald, G., Gasche, R., Zechmeister-Boltenstern, S., Kraus, David, Castaldi, S., Vallejo, A., Rubio, A., Rubio, J.M., Butterbach-Bahl, Klaus

“…Fire is a major factor controlling global carbon (C) and nitrogen (N) cycling. While direct C and N losses caused by combustion have been comparably well established, important knowledge gaps remain on postfire N losses. …”

Greenhouse gas emissions from passive composting of manure and digestate with crop residues and biochar on small-scale livestock farms in Vietnam por Vu, Quynh Duong, Neergaard, Andreas de, Tran, TD, Hoang, HTT, Vu, VTK, Jensen, Lars Stoumann

“…CH4 losses accounted for just 0.4–4.0% of total C losses. Total N losses accounted for 27.1–40% of initial total N in which N2O emissions corresponded to 0.01–0.57% of initial total N, and hence accounted for only 0.1–1.8% of total N losses. …”
