Summary: This study investigated the effects of ridge tillage and plastic film or straw mulching on yield stability, soil water storage, nitrogen budget, and soil nitrogen and organic carbon contents in rain-fed spring maize on the Loess Plateau. The results showed that plastic film mulching increased maize yield and stability, improved water use efficiency, and maintained soil nitrogen and organic carbon contents. However, the potential impact of microplastic contamination should be considered.

Summary: Supplying adequate nitrogen to meet crop demand is crucial for enhancing agricultural sustainability. Proper nitrogen supply can be established by correlating with relative yield, N input and output, and N use efficiency. Appropriate nitrogen supply values range from 325 to 497 kg ha(-1) for summer maize production, ensuring sufficient nitrogen supply for higher yields and reducing environmental nitrogen loss.

Summary: Optimized fertilization is an effective strategy for improving nitrogen use efficiency and maintaining high crop yield. This study investigated the long-term impacts of different nitrogen rates on maize yields and soil nitrogen and carbon dynamics. The results showed that the optimum nitrogen rate and combined organic-inorganic nitrogen rate can achieve similar yields as the farmers' nitrogen rate. Furthermore, substituting 20-30% manure for inorganic fertilizer under the optimum nitrogen rate could help reduce soil nitrogen losses and increase soil organic carbon stock for sustainable agriculture.

Summary: This study aimed to investigate the growth characteristics of companion species, temporal complementarity with maize, and the effect of nitrogen fertilizer on maize-based intercropping. The results showed that intercropping with maize could increase yield, but it was influenced by nitrogen fertilizer levels and co-growth duration. Therefore, when designing maize-based intercropping, factors such as species choice, sowing and harvesting dates should be considered.

Summary: The relationship between maize yield and nitrogen use efficiency (NUE) with inherent soil productivity (ISP) was studied in different ecological regions in Inner Mongolia, China. The results showed a linear-plateau model relationship between maize yield and ISP, with a common inflection point. Increasing ISP can lead to simultaneous increase in maize yield and NUE, and reduce the use of chemical fertilizers and nitrogen loss.

Summary: Belowground interactions mediated by root exudates play a critical role in the productivity and efficiency of intercropping systems. This study investigated the assembly of microbial communities in maize, peanuts, and shared rhizosphere soil, as well as their regulatory mechanisms on root exudates under different planting patterns. The results showed that intercropped maize had significantly increased yield, while intercropped peanuts had significantly decreased yield. Root interactions had a significant effect on the content of ammonium nitrogen and the activities of related enzymes in the rhizosphere soil. Network analysis revealed a reshaped bacterial community composition and increased relative abundance of Bradyrhizobium in the shared soil of intercropped maize and peanuts. These findings suggest that interspecific root interactions improve the soil microenvironment, regulate nitrogen absorption and utilization, and provide a theoretical basis for high yield and sustainable development in maize and peanut intercropping.

Summary: This study evaluated changes in soil phosphorus pools and residual phosphorus after long-term phosphate fertilization. Results showed that higher annual phosphorus rates significantly improved residual soil phosphorus in labile fractions, while initial phosphorus buildup had no effect. The study suggests that the phosphorus accumulation in labile fractions from annual rates can be considered for phosphorus fertilizer recommendation in crop production systems.

Summary: In the claypan soils of the eastern Great Plains, no-till crops have lower yields compared to crops grown with tillage, particularly cereals. The impact of tillage system and N fertilizer placement on corn, wheat, and double-crop soybean yields was assessed over a 14-year study. Results showed that corn yield was significantly affected by tillage and N placement, with no-till consistently resulting in lower yields. Nitrogen fertilization increased corn yield, with subsurface band applications showing a slight advantage. However, tillage had minimal effects on wheat and double-crop soybean yield, and only led to slight increases in soil P and K levels. Overall, tillage and N placement treatments had a greater impact on corn yield and soil properties in this rotation.

Results from this study suggest that while M3 shows strong correlation with AA for certain nutrients, such as K, Mg, and Na, it may lead to overestimation of extractable Ca and CEC in soils with high pH levels.

Summary: The research describes a new method for screening and identifying bacterial consortia that promote the growth of corn. This method utilizes a microfabricated high-throughput screening device, called the microwell recovery array (MRA), to explore the maize rhizobiome for combinations of bacteria that enhance the growth and colonization of the nitrogen-fixing PGPB, Azospirillum brasilense. The study found that bacterial consortia dominated by bacteria from the Acinetobacter-Enterobacter-Serratia genera significantly accelerated the growth of corn plants when co-inoculated with A. brasilense. This research demonstrates a rapid bioprospecting method for identifying complementary PGPB and developing next-generation biofertilizers.
