Application of ABB LGR water isotope analyzer on the partitioning of catchment evapotranspiration fluxesEvapotranspiration (ET) is an important process in the water budget of an ecosystem. Quantifying the components (Esoil and T)) of evapotranspiration is of great significance in revealing the ecohydrological process of alpine inland river basins. At present, the research on Esoil and T is mainly based on the observation site scale to calculate local evapotranspiration components, there are few reports on the changes of evapotranspiration components at the watershed scale. Hydrogen and oxygen stable isotope technology is a good tracer for the ecological hydrological cycle. It is widely used in the study of hydrological cycle Existing studies have used hydrogen and oxygen stable isotope tec...

The crop harvest index (HI) is an important biological parameter to evaluate the level of crop yield and cultivation effectiveness, and it is an important determinant of further improvement of crop yield. It is of great significance for research on the application of crop variety breeding, crop growth simulation, crop management in precision agriculture and crop yield estimation, among other topics. In recent years, Remote sensing has gradually become an effective technical means for obtaining largescale crop HIs because of its advantages in speed, accuracy and coverage area. And unmanned aeri...

Soil properties and substrate quality determine the priming of soil organic carbon during vegetation successionSoil organic matter (SOM), the largest carbon (C) pool in terrestrial ecosystems, is extremely vulnerable to climate and human disturbances. Even a small change in SOM can greatly influence atmosphere CO2 concentration and C balance. Fresh organic matter (FOM), e.g., leaf litter and root exudate, contributes considerably to SOM formation, but can also modify SOC mineralization through the priming effect (PE). While many studies have shown that plant derived C entering the soil would i...

WinRoots: A High-Throughput Cultivation and Phenotyping System for Plant Phenomics Studies Under Soil StressStress due to soil composition, such as salinity, heavy metals, and nutrient deficiency, is a primary cause for crop yield reduction. Crop soil stress tolerance is a complex trait that involves the regulation of a variety of genetic and non-genetic factors such as plant morphology, metabolism, and gene regulatory networks. Traditional crop phenotyping is generally carried out in the field, which is time-consuming and labor-intensive, suffers from low throughput, and can routinely be affe...

In recent decades, massively increasing nutrient discharge from soil erosion, agricultural activity, and anthropogenic sewage has resulted in the significant deterioration and eutrophication of freshwater ecosystems, becoming a pressing environmental problem in many countries. Eutrophication results in undesirable ecological consequences. Phosphorus is an essential bio-limiting nutrient responsible for eutrophication and water quality deterioration, thereinto particulate phosphorus (PP) serves as an important potential source of phosphorus for the growth of phytoplankton and bacteria, thereby ...

Arbuscular mycorrhizal fungi alleviate elevated temperature and nitrogen deposition- induced warming potential by reducing soil N2O emissions in a temperate meadowNitrous oxide (N2O) is one of the most important greenhouse gases and plays an important role in global warming (IPCC, 2013). N2O emissions contribute nearly 10% of anthropogenic climate warming because of their higher global warming potential. The emission of N2O has been influenced by many global changes, including elevated temperature, drought, and nitrogen (N) deposition. Arbuscular mycorrhizal (AM) fungi form mutualist...

Application of Resonon Pika XC2 on Differentiating Cultivars, Growth Stages, Flowers, and Leaves of Industrial Hemp (Cannabis sativa L.)As an emerging cash crop, industrial hemp (Cannabis sativa L.) grown for cannabidiol (CBD) has spurred a surge of interest in the United States. Cultivar selection and harvest timing are important to produce CBD hemp profitably and avoid economic loss resulting from the tetrahydrocannabinol (THC) concentration in the crop exceeding regulatory limits. Hence there is a need for differentiating CBD hemp cultivars and growth stages to aid in cultivar and...

Estimation of biomass and nutritive value of grass and clover mixtures by analyzing spectral and crop height data using chemometric methods Accurate estimation of forage characteristics is needed to guide decision making on fertilization and harvesting schedules for farmers. It is a common practice to estimate forage nutritive value by laboratory analysis, which limits in-field decision making. Field spectroscopy offers a nondestructive approach to obtain crop biochemical information by measuring and analyzing canopy spectral reflectance (CSR). Crop height is an important agronomic parame...

Application of Resonon Pika L on winter wheat yield estimationCrop yield is one of the most critical issues affecting national economic development and food security. Accurate and timely crop yield estimation is essential for precision agriculture and sustainable development, and can provide strong support for agricultural decision-making and management. Traditional crop yield estimation heavily depends on ground field surveys, which are costly, time consuming and prone to large errors. The rapid development of unmanned aerial vehicles (UAVs) offers a new approach to acquire high spatio-tempor...
