Última Influence of slurry and mineral fertiliser application technique on N2O and CH4 fluxes from a barley field Organic Eprints Perälä, Paula; Kapuinen, Petri; Esala, Martti; Tyynelä, Sanna; Regina, Kristiina. The effect of different fertilizer application techniques on nitrous oxide and methane emissions were investigated in a field experiment. Gas fluxes were measured during a five months period in 2001 from a barley field located in Vihti, southern Finland. The effects of different fertilizer application techniques on crop yield and quality were also investigated. According to the results, slurry injection produced the most N2O during the measurement period. Placement of mineral fertilizer produced least N2O. Methane fluxes were close to zero and there were no statistically significant differences between the treatments.

Ano: 2005 URL: http://orgprints.org/8460/1/njf1.pdf Digested slurry as a fertilizer for biogas ley Organic Eprints Kapuinen, Petri; Perälä, Paula; Regina, Kristiina. Digested slurry injected produces in this case comparable yields with mineral fertiliser. Because the primary growth is the largest and of the best quality it should be used for feed as the first option. The re-growths could then be used as a co-substrate in biogas reactors. Digested slurry is a good fertiliser for leys when injected. Injection of non-digested slurry reduces the ammonia emissions and leaching of soluble phosphorus but the significance of the low performance of nitrogen leaves open its fate.

Application of slurry at seeding time produces the best whole crop cereal silage yield without significant drawback in the first cut of timothy next year.

Ano: 2005 URL: http://orgprints.org/8465/1/njf3.pdf Cattle slurry as a fertilizer of whole crop cereal silage (WCCS) when renewing ley Organic Eprints Kapuinen, Petri; Tyynelä, Sanna. Application of slurry at seeding time produces the best whole crop cereal silage yield without significant drawback in the first cut of timothy nect year. Only Italian rye-grass contributes the WCCS yield. Neither Timothy nor Italian rye-grass produce significant yield the same autumn after harvesting the WCCS. Italian rye-grass ley could be established in barley harvested as WCCS in favourable conditions. Tipo: Conference paper, poster, etc. Palavras-chave: Composting and manuring.

In this study, the effects of different application techniques on emissions of nitrous oxide and methane from a barley field were compared.
