“…For example, in the Arctic tundra, higher evapotranspirative losses from bryophyte‐covered soils compared with bare soil are attributed to both the retention of large amounts of water that later evaporates, and bryophyte uptake of deeper soil water via capillary action (e.g. Raz‐Yaseef et al ., 2017; Clark et al ., 2023). Conversely, soil moisture content under bryophytes can be much higher than under other vegetation such as in grasslands (two to four times; Van Tooren et al ., 1985) and boreal forests (Grau‐Andrés et al ., 2021), especially in the top 10 cm (Michel et al ., 2013).…”

SummaryBryophytes, including the lineages of mosses, liverworts, and hornworts, are the second‐largest photoautotroph group on Earth. Recent work across terrestrial ecosystems has highlighted how bryophytes retain and control water, fix substantial amounts of carbon (C), and contribute to nitrogen (N) cycles in forests (boreal, temperate, and tropical), tundra, peatlands, grasslands, and deserts. Understanding how changing climate affects bryophyte contributions to global cycles in different ecosystems is of primary importance. However, because of their small physical size, bryophytes have been largely ignored in research on water, C, and N cycles at global scales. Here, we review the literature on how bryophytes influence global biogeochemical cycles, and we highlight that while some aspects of global change represent critical tipping points for survival, bryophytes may also buffer many ecosystems from change due to their capacity for water, C, and N uptake and storage. However, as the thresholds of resistance of bryophytes to temperature and precipitation regime changes are mostly unknown, it is challenging to predict how long this buffering capacity will remain functional. Furthermore, as ecosystems shift their global distribution in response to changing climate, the size of different bryophyte‐influenced biomes will change, resulting in shifts in the magnitude of bryophyte impacts on global ecosystem functions.

“…Over the years, many lysimeters have been installed worldwide using various designs and installation systems [12][13][14][15][16][17][18][19][20][21][22][23]. ET data derived from lysimeter experiments have been used for many applications, such as studying the water requirements of different crops, evaluating the effectiveness of irrigation strategies, assessing the impact of climate change on ET patterns, and calibrating other methods and techniques for measuring and estimating ET [10,24].…”

An Effective and Affordable Internet of Things (IoT) Scale System to Measure Crop Water Use

Scales are widely used in many agricultural applications, ranging from weighing crops at harvest to determine crop yields to regularly weighing animals to determine growth rate. In agricultural research applications, there is a long history of measuring crop water use (evapotranspiration [ET]) using a particular type of scale called weighing lysimeters. Typically, weighing lysimeters require very accurate data logging systems that tend to be expensive. Recent developments in open-source technologies, such as micro-controllers and Internet of Things (IoT) platforms, have created opportunities for developing effective and affordable ways to monitor crop water use and transmit the data to the Internet in near real-time. Therefore, this study aimed to create an affordable Internet of Things (IoT) scale system to measure crop ET. A scale system to monitor crop ET was developed using an Arduino-compatible microcontroller with cell phone communication, electronic load cells, an Inter-Integrated Circuit (I2C) multiplexer, and analog-to-digital converters (ADCs). The system was powered by a LiPo battery, charged by a small (6 W) solar panel. The IoT scale system was programmed to collect data from the load cells at regular time intervals and send the data to the ThingSpeak IoT platform. The system performed successfully during indoor and outdoor experiments conducted in 2023 at the Clemson University Edisto Research and Education Center, Blackville, SC. Calibrations relating the measured output of the scale load cells to changes in mass resulted in excellent linear relationships during the indoor (r2 = 1.0) and outdoor experiments (r2 = 0.9994). The results of the outdoor experiments showed that the IoT scale system could accurately measure changes in lysimeter mass during several months (Feb to Jun) without failure in data collection or transmission. The changes in lysimeter mass measured during that period reflected the same trend as concurrent soil moisture data measured at a nearby weather station. The changes in lysimeter mass measured with the IoT scale system during the outdoor experiment were accurate enough to derive daily and hourly crop ET and even detect what appeared to be dew formation during the morning hours. The IoT scale system can be built using open-source, off-the-shelf electronic components which can be purchased online and easily replaced or substituted. The system can also be developed at a fraction of the cost of data logging, communication, and visualization systems typically used for lysimeter and scale applications.

“…There are different methods to measure ET, such as the local measurement method (Kandra et al 2023). Lysimeters are one of the local measurement methods that are valuable and reliable for measuring ET (Clark et al 2023) and have the ability to be considered as a tool to validate evapotranspiration parameter estimation methods (Ochoa-Sánchez et al 2019). Although lysimeters are highly accurate in measuring ET, the high cost of these tools and the need for skilled labor can be considered as disadvantages of this method (Dong and Hansen 2023).…”

Actual daily evapotranspiration (ET) can be considered as one of the most important meteorological parameters. One of the main ways to measure ET is using lysimeters, which are expensive tools, and the data obtained from them are not available in most parts of the world. Therefore, the purpose of this research is to provide an intelligent model that can predict ET using data obtained from cheap and available tools. To do this, data from two NE and SE lysimeters located in Potter County, Texas between 1996-1999 were used as input for SVR and SVR-FFA models in 13 scenarios. The results of this study showed that the SVR-FFA model with an error value of 1.22 mm/day for 1996, 1.14 mm/day for 1997, 1.56 mm/day for 1998, and 1.54 mm/day for 1999 has the highest accuracy for all combinations. Among the standalone SVR models, the SVR-13 model has performed better than other SVR combinations for all years with a Willmott's index of agreement above 0.87. The comparison between the inputs used for the models showed that the Rn and PAR parameters had the greatest impact on the accuracy of the SVR and SVR-FFA models, so they increased the accuracy of the models in every four years. One of the limitations of this study is the lack of access to some parameters such as minimum and maximum temperature in the study area. Therefore, it is suggested to measure these parameters and consider them as other inputs to measure the performance of the models.
