Emissions of greenhouse gases during fertilizationof young -spruce forest in southern Sweden (English)
Abstract [sv]

Behovsanpassad gödsling (BAG) ökar skogens tillväxt, vilket kan ha en positivinverkan på kolbalansen. För att öka vår förståelse av vilken effekt gödslingsdoshar på växthusgasutsläpp, har denna studie undersökt respirationen i engranungskog på fastigheten Toftaholm (57°0'N; 14°3'E) med sandning morän ochfrisk markfuktighet, med främsta fokus på emissionerna från lustagas och metan.Resultaten visar på låga halter av lustgasemissioner och för metan sker en fortsattinbindning oavsett gödselgiva. De små ökningarna av växthusgaser indikerade påen fortsatt ökning vid större gödselgiva. För en tänkbar operationell gödselgiva(150khN/Ha och år) kunde ingen signifikant skillnad säkerställas.

Abstract [en]

BAG leads to a greater forest growth, which could have a positive influence on thecarbon balance. To increase our understanding of the effect fertilization have ongreenhouse gas emissions, this study have examined the respiration of a juvenilespruce forest on the estate of Toftaholm (57°0'N; 14°3'E), where the soil-texturewas manly sand-moraine with a medium humidity, with main focus on theemissions of methane and nitrous gas. The results indicated a small increase innitrous gas and a continued net binding of methane independent of amount offertilization. The small increase in greenhouse-gas indicates a continuation withincreased amount of fertilization. For operational productivity with an amount offertilization (150khN/Ha and year) no significance could be determent.
