Nutritional value of crude and partially defatted olive cake in finishing pigs and effects on nitrogen balance and gaseous emissions by Ferrer, Pablo, García-Rebollar, Paloma, Cerisuelo, Alba, Ibanez, M. A., Rodríguez, Carlos A., Calvet, Salvador, de-Blas, Carlos

“…An experiment was performed using pigs to determine the nutritional value of crude (COC) and partially defatted (PDOC) olive cake, and to evaluate their effect on nutrient balance, slurry properties and potential ammonia (NH3) and methane (CH4) emissions. Five experimental feeds were designed; a basal diet and another four diets produced by substituting 100 or 200 g/kg of the basal diet with either COC or PDOC. …”

Paddy rice yield and greenhouse gas emissions: Any trade-off due to co-application of biochar and nitrogen fertilizer? A systematic review by Iboko, M.P., Dossou-Yovo, Elliott Ronald, Obalum, S.E., Oraegbunam, C.J., Diedhiou, S., Brümmer, C.C., Teme, N.G.

“…Combined application of biochar and nitrogen (N) fertilizer could offer opportunities to increase rice yield and reduce methane emissions from paddy fields. However, this strategy may increase nitrous oxide (N2O) emissions, hence its interactive effects on GHG emissions, global warming potential (GWP) and GHG intensity (GHGI) remained poorly understood. …”

The effects of agronomic practices on soil greenhouse gas emissions in maize production systems in Buea, Cameroon by Amahnui, George Amenchwi, Paligwende Nikiema, Veronica Ebot Manga, Aaron Suh Tening, Theophilus Olufemi Isimikalu, Tek B. Sapoka

“…Conventional tillage paired with organic fertilizer yielded the highest CO 2 emissions across both seasons, while methane fluxes were low and largely negative across treatments, indicating that the volcanic upland soils acted as CH 4 sinks. …”

Integrating critical values of soil drivers for mitigating GHGs: An assessment in a sugarcane cropping system by Chalco Vera, Jorge Elías, Curti, Ramiro Nestor, Acreche, Martin Moises

“…The aim of this study was to combine critical values of soil variables determining groups of GHG fluxes with similar and/or opposite direction of carbon dioxide (CO2), nitrous oxide (N2O) and methane (CH4). We determined CO2, N2O, CH4 fluxes, soil temperature, gravimetric soil moisture (GSM), soil inorganic nitrogen (SIN), soil bulk density (SBD), soil porosity (P), and water-filled pore space (WFPS) monthly in three consecutive growing seasons in a sugarcane agroecosystem. …”

Effects of nutrition on digestion efficiency and gaseous emissions from slurry in growing-finishing pigs. I. Influence of the inclusion of two levels of orange pulp and carob meal... by Beccaccia, A., Calvet, Salvador, Cerisuelo, Alba, Ferrer, Pablo, García-Rebollar, Paloma, de-Blas, Carlos

“…An experiment was conducted to investigate the effects of increasing the level of two sources of fibrous by-products, orange pulp (OP) and carob meal (CM), in iso-NDF growing-finishing pig diets on nutrient balance, slurry composition and potential ammonia (NH3) and methane (CH4) emissions. Thirty pigs (85.4 +/- 12.3 kg) were fed five iso-nutritive diets: a commercial control wheat/barley (C) and four experimental diets including two sources of fibrous by-products (OP and CM) and two dietary levels (75 and 150 g/kg) in a 2 x 2 factorial arrangement. …”
