Summary: This study provides scientific evidence for the rational use of crop straw to replace chemical potassium inputs. Long-term field experiments showed that integrating straw return with potassium fertilization improved soil potassium supply and balance, increasing exchangeable and non-exchangeable potassium content in the soil and preventing depletion of non-exchangeable potassium pool under intensive cropping. Additionally, straw return contributed to higher soil available potassium, slow available potassium, and sustained potassium supplying ability of soils.

Summary: This study investigated the physiological responses and candidate genes for ozone tolerance in wheat. It found that sensitive genotypes showed a decrease in net photosynthetic rate and an increase in lipid peroxidation, while tolerant genotypes showed consistent antioxidant responses. Analysis of candidate genes located on chromosome 5A revealed differential expression and sequence polymorphisms between tolerant and sensitive genotypes. This study provides a step forward in understanding the molecular mechanism underlying ozone tolerance in wheat.

Summary: Manure has traditionally been used as a nutrient source in grain crop production worldwide. Irrigation benefits water use efficiency in winter wheat during dry seasons, while manure application improves WUE in winter wheat but decreases it in summer maize. Fertilization strategies have a minor effect on annual water use efficiency of the wheat-maize system.

Summary: The objective of this study was to test the ability of different wheat genotypes to take up nitrogen from preceding legume crops under different water scenarios. The results showed that drought-tolerant genotypes had higher nitrogen nutrition index, biomass, yield, and nitrogen output under low water and nitrogen inputs, while other genotypes performed better under non-limiting conditions. Therefore, this study confirms differences between wheat genotypes in nitrogen uptake from preceding legumes in crop rotations under different water levels and highlights the potential of nitrogen nutrition index to assess wheat nitrogen status.

Summary: Excessive use of water resources poses threats to agriculture, business, and populations in China, India, and the USA, with crop production set to play a crucial role in sustainable water use. Plastic mulching reduces water footprint in crop production, but also decreases volumetric water availability. Different crops in China have varying water footprints, with the potential for saving water by considering appropriate growing regions and nitrogen fertilizer applications in conjunction with plastic mulching practices.

Summary: Water deficits in crop production, caused by depleting water supplies and high water-demanding crops, have become a major concern in semiarid regions of China. A six-year field experiment was conducted to evaluate soil water recovery and fertility after converting lucerne to different crops on the western Loess Plateau. The findings show that all rotation types gradually increased soil water content, but decreased organic carbon and total nitrogen in the soil.

Summary: Bacterial diversity and its functions in soil are crucial for soil health. This study investigated the effects of N fertilization on bacterial communities and soil physicochemical properties. The results showed that N fertilizer significantly altered the diversity and abundance of bacterial communities, with Proteobacteria, Actinobacteria, Acidobacteria, and Chloroflexi being the most abundant phyla. The optimal N fertilizer application rate (N105) promoted soil microbial diversity and abundance, while high N enrichment led to an increase in heterotrophic N-fixing microorganisms. The study also highlighted the importance of soil NO3-N in determining bacterial community function under different N fertilizer treatments.

Summary: This study investigated the mechanism of melatonin in mitigating chromium toxicity in maize plants using transcriptomic and physiological approaches. The results showed that melatonin treatment significantly reduced the chromium content in leaves, while the chromium content in roots remained unchanged. Further analysis revealed that melatonin alleviated chromium-induced oxidative stress by affecting cell wall polysaccharide biosynthesis, glutathione metabolism, and redox homeostasis. These findings highlight the important role of melatonin in alleviating chromium toxicity in maize.

Summary: A meta-analysis of 86 studies has shown that nitric oxide (NO) can significantly improve plant biomass, alleviate oxidative damage, and increase the content of Ca, Fe, and Mg in heavy metal-stressed plants. The optimal concentration of SNP (an NO donor) for hydroponic culture is in the range of 75-150 μM. These findings provide valuable insights for the future application of NO as a plant growth regulator for enhancing heavy metal stress tolerance in agriculture and breeding.

Summary: This study investigated the variations in Cd accumulation and tolerance among four maize genotypes with different root morphology, and found a positive correlation between root characteristics and Cd accumulation. Genotypes Shengrui999 and Zhengdan958 showed higher Cd accumulation and tolerance under Cd stress. Cd toxicity led to membrane degradation and reduced starch reserves in maize plants. The greater tolerance of Shengrui999 and Zhengdan958 may be attributed to factors such as root biomass, shallower root depth, higher Cd content, and accumulation of osmolytes and antioxidant activities.
