Summary: Agricultural managed aquifer recharge (Ag-MAR) has been receiving increased attention as a method to intentionally recharge groundwater by flooding farmland with excess surface water. However, concerns about nitrate (NO3-) contamination, greenhouse gas emissions, and crop tolerance to prolonged flooding remain. This study conducted a large-scale experiment to assess the effects of Ag-MAR on soil nitrogen biogeochemical transformations, nitrate leaching, soil conditions, and crop yield. The results showed that nitrate leaching was the dominant nitrogen loss pathway, and prolonged flooding led to a significant decrease in crop yield.

Summary: This study investigates the effects of different root architectures on soil water infiltration, volumetric water content, and soil water pressure head using dye infiltration experiments and HYDRUS-1D modeling. The results show that root channels can serve as preferential flow paths for water infiltration and percolation into the soil. The presence of plant roots reduces the propagation time of the wetting front, increases the volumetric water content, and affects the soil water pressure head.

Summary: Japanese plum farming in the Western Cape is a significant industry for export and job creation, but information on its water requirements in the semi-arid area is lacking. This study used experimental data and modeling to determine seasonal plum water requirements. The estimated water requirements ranged from 524 mm to 864 mm, depending on the plum variety and region. Irrigation management should consider reducing leaching and impacts on water quality while also considering the farm's economics.

Summary: Understanding the spatial distributions and effects of soil water, temperature, and nutrients on maize growth and yield is important for optimizing drip fertigation regimes. A 2-year field experiment was conducted in arid northwestern China, with different irrigation levels and fertilization rates. The results showed that irrigation level affected soil water content, temperature, and nitrate nitrogen content, while fertilization rate influenced root length density. Grain yield, water use efficiency, and partial factor productivity were influenced by irrigation level and fertilization rate. The recommended drip fertigation regimes for spring maize in arid northwest China were determined.

Summary: This study aims to identify and rank the main soil-climate factors that hinder the adoption of cover crops, and finds that clay content is the most significant barrier. The inclusion within Nitrate Vulnerable Zones has little influence on cover crop adoption. Developing technical solutions for establishing and destroying winter cover crops on clay soils can improve global water quality.

Summary: This study used the HYDRUS 1D model to investigate the performance of bioretention systems in cold regions during winter snowmelt, spring runoff, and summer large storms. The research found that the effective hydraulic conductivity (K-S) values of the soil media were similar for winter snowmelt and spring runoff when the soil temperature was around -0.5 degrees C. Preferential flow is likely to occur in soil media during winter or spring in cold regions. The summer modeling showed that bioretention could significantly reduce peak flow, ponding depth, and duration for large storm events.

The HYDRUS-1D model showed good performance in predicting soil water content and temperature in Andosols. Specifying soil layer-specific hydraulic parameters can significantly improve the model's fit, while water vapor has a negligible impact on total water flux and soil temperature dynamics.

Summary: The solar greenhouse is a common protected structure for crop production when ambient temperatures are low. In the North China Plain, a sunken solar greenhouse (SSG) is used in winter to take advantage of higher temperatures. A four-season experiment with tomato crops in a commercial SSG found that the temperature inside the SSG could be more than 20 degrees C higher than outside in winter, leading to favorable tomato growth and yields. The sap flow of the crops was influenced by solar radiation, vapor pressure deficit, and temperature, with decoupling coefficient indicating strong radiative influences in the SSG. Crop coefficients varied throughout the seasons, with higher sap flow in winter compared to summer, suggesting the need for irrigation scheduling considerations.
