Summary: Wheat breeding has improved yield potential, but the impact of variety on nitrogen agronomic efficiency (NAE) and its interaction with soil fertility is unknown. Through a large-scale analysis of field trial data across China's wheat production zones, we found that variety significantly affected NAE, with high variability among different varieties in low, moderate, and high fertility soils. Selecting superior varieties based on soil conditions could decrease the yield gap by 67% and improve food security while reducing fertilizer inputs.

Summary: This study measured and simulated the effects of different management practices, including irrigation, stover retention, and cover crop use, on soil N2O emissions in a long-term continuous corn system. The results showed that reducing stover retention could decrease soil N2O emissions and deficit irrigation could reduce soil N2O emissions in the presence of cover crops. This study improves our understanding of the mechanisms behind the effects of agricultural management on soil N2O emissions.

Summary: Optimizing field border length can reduce soil nitrogen residues and increase nitrogen absorption and utilization by wheat plants in the Huang-Huai-Hai Plain of China. The study found that irrigation with a border length of 40 meters significantly improved nitrogen transport and grain nitrogen accumulation, while reducing soil inorganic nitrogen residue. This resulted in higher grain yield and nitrogen fertilizer utilization compared to other irrigation methods.

Summary: Deficit irrigation (DI) is an effective technique to improve water use efficiency (WUE) in maize cultivation. A 3-year field experiment was conducted in Northeast China to investigate the combined effects of DI at the seedling stage and N fertilization on maize growth and yield. The results showed that DI positively impacted seedling growth and had similar or better effects on reproductive growth, grain yield, WUE, and NUE compared to well-watered plants. However, the effects of DI varied depending on the initial soil water content and precipitation. N fertilization compensated for the limited seedling growth under DI.

Summary: The study found that peanut residue incorporation had no significant effect on the subsequent wheat and peanut yield, but significantly increased the annual yield, evapotranspiration, and water use efficiency of the summer peanut-winter wheat system, suggesting that the impact of residue incorporation on multiple cropping systems is more significant than a single crop season.

Summary: Water and nitrogen inputs have positive effects on wheat yield, WUE, and NUE, but exceeding optimal levels decreases the benefits. Actual yield, WUE, and NUE are significantly lower than potential attainable levels, and there are varying saving potentials for water and nitrogen in wheat production across China.

Summary: The objective of this study was to investigate the effects of surge-root irrigation and nitrogen coupling on apple yield, soil water and nitrogen distribution, and enzyme activity in the Loess Plateau of China. The results showed that increasing irrigation and nitrogen levels widened the distribution of soil water and nitrogen. Additionally, the study found that different irrigation and nitrogen levels had varying effects on apple yield, water use efficiency, nitrogen fertilizer partial productivity, and soil environment. The findings can provide a scientific basis for apple water and nitrogen management in the Loess Plateau of China.

Summary: Biodegradable mulches have the same temperature- and moisture-preservation effects as ordinary plastic mulches before degradation. After degradation, rainwater enters the soil through the damaged parts, improving precipitation utilization. The study found that the effective infiltration of precipitation decreases and then increases with increasing precipitation, and the effective infiltration ratio of precipitation increases as the damage to the biodegradable film increases under the same precipitation intensity.

Summary: This study investigates the improvement of subsurface pipe layout and long-term soil salinization control in arid and semi-arid agricultural areas. Field experiments and numerical model calculations were conducted to understand water and salt migration during soil amendment. The results show a positive correlation between salt concentration in surface pipe drainage and soil salt content, as well as pipe depth and a negative correlation with irrigation water amount and crop spacing. The findings provide insights for the optimal layout of subsurface pipes to develop strategies for desalination and salt control.

Summary: This study investigates the dynamic properties of soil moisture, salinity, ions, and groundwater in the Hetao Irrigation District in China. The results show that soil moisture increases with soil depth in both cultivated and fallow soils, and salinity exhibits an increasing trend during specific time periods. The characteristic factors affecting salt accumulation differ between cultivated and fallow soils. This study provides a theoretical basis for preventing and controlling soil salinization in arid and semiarid areas.
