Trend for Soil CO2 Efflux in Grassland and Forest Land in Relation with Meteorological Conditions and Root Parameters

The key process in understanding carbon dynamics under different ecosystems is quantifying soil CO2 efflux. However, this can change annually as it depends on environmental variables. results of paper present the effects root network, temperature, and volumetric water content efflux, which were investigated Retisol two types land uses Western Lithuania 2017–2019: forest grassland. It was determined that average efflux grassland 32% higher than land. across uses, tended to increase following order: 2017 < 2018 2019. Dry weather conditions with high temperatures during vegetation period governed by 14%. Soil temperature (up 20 °C) 23–25%) had a positive effect Retisol. We established root’s activity plays one main roles production rate—in both influenced length density volume.
