Farklı Sulama Yöntemlerinin Topraktan Karbondioksit (CO2) Çıkışı Üzerine Etkisi

Abstract

Global warming and greenhouse gas emission are one of the important researches in recent years. There are a wide range of greenhouse gas resources and one of them is agricultural activities. During agricultural activities CO 2 emission from soil occurs. Water requirement in plant production is met by using various irrigation methods. The most widely used methods are drip irrigation, sprinkler irrigation and surface irrigation. Drip irrigation in recent years has been preferred due to its less water use. This study was carried out to determine soil CO 2 emission in apple orchard of Jersey Mac apple cultivars grafted on M9 which was irrigated by drip irrigation, sprinkler irrigation and surface irrigation methods. In the study, soil CO 2 flux was measured after irrigation. CO 2 flux of drip, sprinkler and surface irrigation was 0.065, 0.071 and 0.084 g.CO 2 .m -2 .h -1 , respectively Evaporation from the soil was 8.06, 8.85 and 8.95 g.H 2 O.m -2 .h -1 for drip, sprinkler and surface irrigation, respectively. Even though there were no significant differences among irrigation methods in terms of CO 2 flux and evaporation value (P>0.05), these results indicated that CO 2 emission and evaporation values in drip irrigation method tended to decrease.
