“…Targeted design strategies may be capable of increasing synergistic relationships among soil and vegetation structures to create co-benefits. For example increasing vegetation in LID can increase infiltration [68,69], biodiversity [70], and shading, while decreasing nutrient export [71][72][73] and urban heat islands [74].…”

Low-impact development (LID) is a common management practice used to infiltrate and filter stormwater through vegetated soil systems. The pollutant reduction potential of these systems is often characterized by a single pollutant removal rate; however, the biophysical properties of soils that regulate the removal of pollutants can be highly variable depending on environmental conditions. The goal of this study was to characterize the variability of soil properties and nitrogen (N) cycling rates in bioretention facilities (BRFs). Soil properties and potential N cycling processes were measured in nine curbside bioretention facilities (BRFs) in Portland, OR during summer and winter seasons, and a subset of six sites was sampled seasonally for two consecutive years to further assess temporal variability in soil N cycling. Potential N cycling rates varied markedly across sites, seasons, and years, and higher variability in N cycling rates was observed among sites with high infiltration rates. The observed seasonal and annual changes in soil parameters suggest that nutrient removal processes in BRFs may be highly variable across sites in an urban landscape. This variability has important implications for predicting the impacts of LID on water quality through time, particularly when estimated removal rates are used as a metric to assess compliance with water quality standards that are implemented to protect downstream ecosystems.

“…In addition, strong rainfall usually results in surface runoff happening faster than in rainwater infiltrate soils [35]. Previous research has proven that rainfall intensity and kinetic energy are key factors for determining the formation of runoff, and the rate of crust formation and groundwater infiltration [36][37][38]. Heavy rainfall intensity could shorten the formation time of runoff and sharply decrease the infiltrate curve [39,40].…”

Crop coefficient (Kc) is one of the most significant parameters for crop water demand prediction and irrigation scheduling. However, there is a lack of knowledge about water vapor and Kc in tea plantation ecosystems. This study explored and determined the actual evapotranspiration (ETc) and Kc of two cultivars of tea (Camellia sinensis), clone variety Baiye1 (BY1) and Longjing43 (LJ43), based on lysimeter data. An estimation was made for both for ETc and adjusted ETc, and the corresponding Kc and adjusted Kc. The results showed that the adjusted ETc and Kc values revealed a minor fluctuation when compared to the ETc and Kc values during the experimental period, which indicated that the adjusted ETc and Kc values were more precise and practical to field conditions. The average adjusted Kc values were 0.71 (range of 0.43–1.02) for BY1 and 0.84 (range of 0.48–1.22) for LJ43. Additionally, heavy pruning can decrease ETc and Kc values, possibly due to the lower level of LAI after pruning. Moreover, it is clearly manifested that BY1 consistently had lower ETc and Kc values than those of LJ43 because of plant growth status differences between BY1 and LJ43. Overall, our study proposed a reliable reference of Kc in tea plantation, and illuminated the effects of pruning and plant growth differences on Kc, which could provide a strong basis for precise irrigation in tea plantations in a subtropical climate.

“…However, this study lacked the necessary means to estimate runoff, which likely led to signi cant deviations in the nal water ux calculations. Nevertheless, previous study reported that runoff typically occurs during heavy rainfall events and increases with higher rainfall amounts (Alizadehtazi et al,2020;Liu et al, 2019;Wang et al,2015;). and when a certain critical rainfall intensity is reached, water will be lost as runoff because the soil cannot absorb and retain it, and an eventual maximum leachate ux will occur (Wang et al, 2018).…”

Background and aims Great concern has long been raised about nitrate leaching in cropland due to its possible environmental side effects in ground water contamination. we conducted a comparative study on monitoring methods for nitrate N leaching in tea plantation soils.Methods Here we employed two common techniques to measure nitrate leaching in tea plantation soils in subtropical China. Using drainage lysimeter as a reference method, the adaptability of estimating drainage and nitrate leaching by combining the water balance equation with the suction cup technique was investigated.Results The final cumulative leachate volume for the calculated and measured method was 721.43 mm and 729.92 mm respectively during the study period. Meanwhile, The cumulative nitrate leaching loss from the lysimeter and suction cup-based method was 47.45 kg ha− 1 and 43.58 kg ha− 1 under lysimeter nitrate concentrations ranging from 7 mg L− 1 to 13 mg L− 1, 156.28 kg ha− 1 and 79.95 kg ha− 1 under lysimeter nitrate concentrations exceeding 13 mg L− 1.Conclusion The suction cup-based method could be an alternative way of monitoring nitrate leaching loss within a certain range of nitrate concentrations in leachate. Besides, lower results occurred in suction cup samplers due to lack of representative samples which mainly leached via preferential flow when in strong leaching events. Thus, it is advisable to increase sampling frequency under such special conditions. The results of this experiment can serve as a reference and guidance for the application of ceramic cups in monitoring nitrogen and other nutrient-ion leaching in tea plantation soils.
