Rudeninio žemės dirbimo intesyvumo įtaka CO2 dujų emisijai ir dirvos temperatūrai

Tillage can significantly influence soil temperature and CO2 gas emission affecting global climate change. The study was aimed to determine the influence of different tillage systems on temperature changes at the 0 - 10 cm soil depth in four fields to evaluate the changes of CO2 emission from soil. On airy loam CO2 emission from soil was biggest under traditional soil tillage 551 ppm its 35 % bigger than No-tillage. No-tillage application might be a measure to reduce CO2 emission from soil because it exhibits a lower vapor exchange rateVytauto Didžiojo universitetasŽemės ūkio akademij
