Summary: This study conducted continuous field observation experiments to obtain a large amount of root, soil hydraulic conductivity, and physicochemical property indices data. It was found that root tip density plays an important role in root water uptake in alpine meadows. A distribution function of root tip density in alpine meadows was constructed, and a corresponding root water uptake model was established. The results showed that the root tip density function is more accurate than the root length density function in reflecting the pattern of root water uptake.

Summary: This review article discusses the uptake of mineral nutrients by plant roots and their relationship with root hairs and lateral roots, focusing on the expression pattern of transporters in Arabidopsis and rice. The authors propose different uptake systems for mineral elements based on root anatomy and transporter localization, and also examine the role of Casparian strips in nutrient uptake.

Summary: This paper presents an automated detection of tip-burn lettuce grown indoors using a deep-learning algorithm. The YOLOv5 model achieves the highest accuracy in detecting tip-burns on lettuce images captured under various light conditions. Early detection of tip-burn can help growers adjust lighting and controlled environment parameters to increase the freshness of lettuce grown in plant factories.

Summary: This study examined the plasticity of root system architecture (RSA) traits in eight bottle gourd genotypes from different geographical origins and found that increased root diameter and volume may be a response to water deficit. The Chilean genotypes had the highest water productivity, and the Illapel and Chepica genotypes showed higher root diameter, root volume, and water productivity under water-deficit conditions. These genotypes may be promising drought-tolerant candidates for breeding programs.

Summary: The study found that the nozzle with a droplet size of 11.24 μm had the least impact on the chemical properties of the nutrient solution, resulting in stable lateral root growth and increased biomass yield. Misting with the N1 nozzle at a 30-min intervals helped increase the root-to-shoot ratio and enhance the uptake of phosphorous, potassium, and magnesium by the plants.

Summary: The study measured water isotopes in trees and soil from apple orchards in the Chinese Loess Plateau, finding that with increasing orchard age, root water uptake depth also increased. Deep soil water contributed significantly to tree water uptake in older orchards. In wet years, apple trees relied less on deep soil water compared to normal years.

Summary: Low VPD promotes potassium uptake by facilitating root system development, increasing nutrient absorption, and biomass accumulation. The higher biomass also enhances potassium accumulation, promoting photosynthesis. Low VPD facilitates root system development and enhances potassium uptake.

Summary: Widespread contamination of PFAS in agricultural areas is mainly caused by the application of sewage sludge. The variation in reported plant uptake levels of PFAS poses a barrier to managing the contaminated land. Factors such as the chemical composition of PFAS, soil conditions, and plant physiology contribute to this variation. Further research and data collection are needed to understand the mechanisms of PFAS uptake and develop predictive models. A conceptual framework linking plant PFAS uptake drivers to phytomanagement approaches can provide support for land managers.

Summary: This study investigated salt accumulation in the root zone of curly lettuce plants at the end of the irrigation season compared to the beginning. Different irrigation methods were used, and it was found that effective washing through a good drainage system at the end of the growing season is crucial for sustainable irrigated agriculture.

Summary: The protection and impact of forestry practices on wetlands' hydrological functions, including sediment retention, groundwater recharge, flood reduction and low flow augmentation, are explored in the literature review. The contribution of wetlands to these functions varies with wetland types, as highlighted by experts. The review categorizes wetlands to consider their specific contributions to hydrological functions affected by forest harvesting.

Summary: Snowmelt contributes significantly to groundwater recharge in snow-dominated regions. A new tracer method based on dissolved gases offers consistent estimates of snowmelt recharge dynamics, unlike stable water isotopes which can be biased due to variations in snow isotopes and difficulty measuring snowmelt directly. This method also provides insights into biological N-fixation pathways in boreal forest soils.

Summary: The boreal forest is considered low productivity due to cold climate and poorly drained soils causing peatlands. Partial harvest may be more effective than clearcutting to mitigate high water table and limit peatification. Temperature has a positive effect on water table and stem diameter variations.

Summary: Integrated water management, with a focus on controlling the water table, can significantly increase yield and water use efficiency in cropping systems. Monitoring water table depth and soil properties is essential for intelligent water management. Additionally, understanding the periodic fluctuations in water table depth and their relationship with precipitation can help optimize water management strategies.

Summary: Advancements in sensor technology have made the continuous and spatially distributed data of snow mass more accessible and accurate. CRNP is able to measure deep snowpacks, GMON is the most mature instrument for typical snowpacks, FMCW radar is highly sensitive to wet snow, and GNSSr can estimate multiple key snowpack parameters simultaneously.
