Forest ecosystems significantly contribute to the global organic carbon (OC) pool, exhibiting high spatial heterogeneity in this respect. Some of the components of the OC pool in a forest (woody aboveground biomass (wAGB), coarse root biomass (CRB)) can be relatively easily estimated using readily available data from land observation and forest inventories, while some of the components of the OC pool are very difficult to determine (fine root biomass (FRB) and soil organic matter (SOM) stock). The main objectives of our study were to: (1) estimate the SOM stock; (2) estimate FRB; and (3) assess the relationship between both biotic (wAGB, forest age, foliage, stand density) and abiotic factors (climatic conditions, relief, soil properties) and SOM stocks and FRB in temperate forests in the Western Carpathians consisting of European beech, Norway spruce, and silver fir (32 forest inventory plots in total). We uncovered the highest wAGB in beech forests and highest SOM stocks under beech forest. FRB was the highest under fir forest. We noted a considerable impact of stand density on SOM stocks, particularly in beech and spruce forests. FRB content was mostly impacted by stand density only in beech forests without any discernible effects on other forest characteristics. We discovered significant impacts of relief-dependent factors and SOM stocks at all the studied sites. Our biomass and carbon models informed by more detailed environmental data led to reduce the uncertainty in over- and underestimation in Cambisols under beech, spruce, and fir forests for mountain temperate forest carbon pools.

Abstract Background: Traditional irrigation methods in protected vegetable production such as furrow irrigation result in low water use efficiency. New techniques, such as drip irrigation, micro-sprinkling irrigation have been developed for improving water use efficiency. However, these techniques have not been tested in greenhouse celery production. In this study, three different irrigation techniques micro-sprinkler irrigation (MS), furrow irrigation under plastic film mulching (PF) and micro-sprinkler irrigation under the plastic film mulching (MSP) were investigated whether the three techniques can improve the yield, quality and water use efficiency of greenhouse-grown celery, compared to furrow irrigation (FI). Results: The individual plant weight of celery was higher under MS, PF and MSP than under FI in both autumn season crop (AC) and spring season crop (SC), compared to FI. In AC and SC, the economic yield of celery increases under MSP by 54.18% and 49.55%, the economic yield of celery increases under PF by 30.37% and 34.10%. The irrigation amount of MSP was 151.69 and 179.91 m3 667 m-2 in AC and SC, which was 23.13% and 27.27% lower than that of FI. The irrigation amount of PF was 151.69 and 196.78 m3 667 m-2 in AC and SC, which was 23.13% and 20.45% lower than that of FI. PF and MSP reduced the irrigation amount of celery cultivation in greenhouse, and soil evaporation content. Conclusions: In short, MSP and PF promoted the growth and yield of celery in greenhouse with improved quality and water use efficiency.
