Carbon Dioxide Efflux of Bare Soil as a Function of Soil Temperature and Moisture Content under Weather Conditions of Warm, Temperate, Dry Climate Zone

It is difficult to estimate the contribution of individual sources to the total CO2 efflux from soil with vegetation.Long-term experiments with bare soil will provide useful conclusions.In this study, we aimed to mathematize the effect of soil temperature and soil moisture content on bare soil CO2 efflux in a four-season semiarid region to assess t
