The effect of ryegrass on CO2 flux from cultivated peat soils
Berglund, Örjan; Berglund, Kerstin
Abstract
To be able to quantify the net CO2 emission from cultivated soils there is a need to distinguish between SOMderived CO2 respiration and plant-derived respiration. The methods usually used in measuring the CO2 emission from soil measure the total CO2 flux. In this investigation we used the root exclusion method to separate the plant-derived respiration from total CO2 emission. The plant-derived contribution was estimated to be between 28 and 68% of total CO2 emission. Due to the priming effect the root exclusion method is less reliable late in the season
