“…The National Aeronautics and Space Administration (NASA) Earth Ventures 1 Airborne Microwave Observatory of Subcanopy and Subsurface (AirMOSS; https://airmoss.jpl.nasa.gov/) is a new airborne P-band synthetic aperture radar (SAR) designed to provide direct retrievals of root-zone soil moisture (RZSM) up to 120 cm in depth (depth of penetration varies depending on the amount of vegetation cover) using active remote sensing (Tabatabaeenejad et al, 2015). As its name implies, RZSM is a critical soil moisture state variable that influences plant functioning, including photosynthesis (Xia et al, 2017), ecosystem respiration (Flanagan & Johnson, 2005), and soil respiration (Ito & Ishida, 2016).…”

This study examines the impact of variation in root-zone soil moisture (RZSM), a key component of the Earth's hydrologic cycle and climate system, on regional carbon fluxes across seven North American ecosystems. P-band synthetic aperture radar-derived RZSM estimates were incorporated into the ecosystem demography (ED2) terrestrial biosphere model through a model-data blending approach. Analysis shows that the model qualitatively captures inter-daily and seasonal variability of observed RZSM at seven flux tower sites (r = 0.59 ± 0.26 and r = 0.70 ± 0.22 for 0-10 and 10-40 cm of soil layers, respectively; P < 0.001). Incorporating the remotely sensed RSZM estimates increases the accuracy (root-mean-square deviations decrease from 0.10 ± 0.07 and 0.09 ± 0.06 m 3 ·m −3 to 0.08 ± 0.05 and 0.07 ± 0.03 m 3 ·m −3 for 0-10 and 10-40 cm of soil layers, respectively) of the model's RZSM predictions. The regional carbon fluxes predicted by the native and RZSM-constrained model were used to quantify sensitivities of gross primary productivity, autotrophic respiration (R a ), heterotrophic respiration (R h ), and net ecosystem exchange to variation in RZSM. Gross primary productivity exhibited the largest sensitivity (6.6 ± 10.7 kg·cm −2 ·year·θ −1 ) followed by R a (2.9 ± 7.3 kg·cm −2 ·year −1 ·θ −1 ), R h (2.6 ± 3.1 kg·cm −2 ·year −1 ·θ −1 ), and net ecosystem exchange (−1.7 ± 7.8 kg·cm −2 ·year −1 ·θ −1 ). Analysis shows that these carbon flux sensitivities varied considerably across regions, reflecting influences of canopy structure, soil properties, and the ecophysiological properties of different plant functional types. This study highlights (1) the importance of improved terrestrial biosphere model predictions of RZSM to improve predictions of terrestrial carbon fluxes, (2) a need for improved pedotransfer functions, and (3) improved understanding of how soil characteristics, climate, and vegetation composition interact to govern the responses of different ecosystems to changing hydrological conditions.

“…When normalized by soil temperature, the daily soil respiration rate is highest when soil moisture is at the field capacity and linearly declines with an increase or reduction in soil suction (pF). As soil suction increases, the soil becomes dryer and vice versa (Ito and Ishida, 2016).…”

Carbon dioxide (CO 2 ) is a signifi cant greenhouse gas (GHG) accounting for 60% of the total greenhouse effect. Soil respiration is a measure of the CO 2 released from soil. Rice was the largest contributing plant commodity of total emission by 12%. In the event of growing threats of global warming due to GHG emissions, reducing CO 2 emission by sequestering C in the soil is of supreme concernment. Improved management practices can rebuild C stocks in agricultural soils and help mitigate CO 2 emissions. A fi eld study to assess how organic soil amendments infl uence soil respiration, C-organic content, and soil properties was conducted in upland paddy fi eld. Treatments were: chemical fertilizer (F1), combination of chemical fertilizer and cow dung manure (F2), chemical fertilizer and vermicompost (F3), chemical fertilizer and liquid vermicompost powder (F4), cow dung manure+biochar (F5), vermicompost+biochar (F6) and liquid vermicompost powder+biochar (F7). All treatments tested almost had the same pattern of respiration rates starting before the application of the organic soil amendment until three months after planting. The highest respiration rate was found at 1 month after planting. Soil amendment (F4 and F7) had the lowest soil respiration rates in some measurements. The highest organic C content at three months after planting was found in the F6 and F3 treatments. The most infl uential factor on the respiration rate are soil moisture content and soil temperature. The results demonstrate the viability of vermicompost either in combination with chemical fertilizers or alone for soil amendment to maintain organic soil carbon for short period of time (~ 3 months).

“…Moreover, mowed grass can be decomposed by microorganisms, resulting in enhanced soil respiration. Previously, we had observed soil respiration in the apple orchard for four years and found that it was strongly affected by the amount of mowed grass ( Ito and Ishida, 2016). However, few studies have discussed in the effect of grass mowing on the overall CO 2 flux of orchards.…”

To investigate the reasons for irregular and severe decreases in net ecosystem production (NEP) in a sod-cultured apple orchard for better understanding orchard carbon dynamics, CO 2 flux observation was conducted from April to November (2013 and 2014) using two sets of eddy covariance equipment on different towers that were 15 m apart. Special attention was paid to the effect of grass mowing, which was conducted ten times during the observation period. In the latter half of, or just after the grass mowing period, gross primary production (GPP) on fine (sunny) days decreased to 50% -73% of the level before the grass mowing nine out of ten times, whereas ecosystem respiration (RE) did not decrease or slightly increased. As a result, NEP (= GPP−RE) on fine days drastically diminished after every grass mowing event. Moreover, three other moderate NEP decreases were observed, in addition to mowing events. Two of these events, which occurred 9 -10 days before apple flowering, were possibly caused by a temporal increase in the respiration of apple tree. The remaining event, which occurred immediately after the drought period, was possibly caused by the recovery of microorganism and root respirations. Moreover, in comparing the daily GPP trend in 2013 and 2014, it was apparent that meteorological conditions, such as low temperature from April to May or severe soil water deficiency and low solar radiation in the vigorous growth stage, also negatively affected the population photosynthesis of the orchard.
