Summary: The study found that moderate nitrogen fertilizer application can significantly improve the growth, yield, and biochemical attributes of carrots and beetroot, but excessive nitrogen levels do not show significant effects. Principal component analysis shows significant correlations among the observed parameters.

Summary: Micronutrient deficiencies or hidden hunger is a major public health problem, particularly in low- and middle-income countries, with significant impact on child development. Traditional methods of treatment and prevention have not always been effective and may have undesired side-effects. Gut microbiota, along with the gastrointestinal mucosa, plays a crucial role in enhancing the absorption of micronutrients and protecting against pathogens. However, the exact relationship between micronutrient malnutrition and gut microbiota is still poorly understood. This review provides current knowledge on the interaction between micronutrients and gut microbiota, specifically focusing on iron, zinc, vitamin A, and folate.

Summary: By appropriately managing zinc and nitrogen fertilizers, it is possible to increase the concentrations of zinc and anthocyanins in purple rice. Research has shown that environmental factors, in addition to genetic factors, can affect the concentrations of zinc and anthocyanins in rice during cultivation.

Summary: In rain-fed areas, reducing nitrogen fertilizer application and combining with biochar can decrease N2O emissions and increase yield. In this study, reducing nitrogen fertilizer application and applying 10 t of biochar resulted in increased yield and minimized N2O emissions in a rain-fed winter wheat ecosystem.

Summary: This research investigated the effects of biofertilizers and organic fertilizers on reducing chemical fertilizer consumption and improving effectiveness. The results showed that biofertilizers had a positive impact on lettuce and broccoli growth and yield, and could save 50% of chemical fertilizers.

Summary: This study investigated the impact of different potassium fertilizer application rates on sweet potato yield and economic implications. The results showed that increasing potassium fertilizer application did not increase sweet potato yield, but exhibited a quadratic trend within a certain range. The optimal fertilizer recommendation was 174 kg/ha of K2O. This study suggests that potassium fertilizer can be applied at lower rates than the recommended level while still achieving comparable sweet potato yields.

Summary: Chemical fertilizers are commonly used to meet crop nutritional demands and boost yields, but their high costs and excessive application have negative effects on soil and environmental health. Vermicompost, an organic amendment, offers potential to reduce dependence on chemical fertilizers while providing sustainable nutrient supply to crops and maintaining soil health.

Summary: This study evaluated the effects of N fertilizer on rice yield and grain Zn concentration, finding that different rice varieties had varying responses to soil and foliar N application. The study suggests that N and Zn act synergistically in affecting the accumulation of grain Zn in rice, regardless of the initial grain Zn and yield potential of rice varieties.

Summary: The Yellow River Delta is a significant grain production area in China, but excessive use of chemical fertilizers has negatively affected grain production safety. This study collected data on the application of N, P, K fertilizers from 2011 to 2020 in Dongying City and conducted surveys on fertilizer usage by small farmers. The results showed a decrease in overall fertilizer usage since 2015, but excessive application of macro element fertilizers was observed. Compound fertilizer usage increased over the 10 years of research. It is important to implement scientific measures to reduce chemical fertilizer usage and promote sustainable agriculture in the Yellow River irrigated area.

Summary: Research in Northeast China found that soil selenium deficiency has significantly decreased, but crop products still have low selenium levels due to weak soil-plant transfer. Climate conditions and soil properties were identified as key factors influencing soil selenium distribution, and the challenge remains in ensuring sufficient selenium content in agricultural products for residents in selenium-deficient areas, particularly in China's growing agricultural production environment.

Summary: Cassava is becoming increasingly important in Nigeria, but current yields are low due to poor soil fertility and lack of improved germplasm and crop management. Field experiments conducted over two years with 230 farmers showed that increasing plant density and fertilizer application can significantly improve cassava yields.

Summary: Low planting density and irrational nitrogen fertilization are common practices in smallholder maize production in the Huanghuaihai region of China. A 2-year field experiment was conducted to study the effects of N application and planting density on maize phenology, dry matter accumulation, profit, yield, N uptake, and efficiency. The results showed that increasing N input and planting density delayed physiological maturity and enhanced dry matter accumulation. Optimal combinations of N application and planting density were found to increase grain yield, profit, and nitrogen use efficiency. Therefore, adjusting planting density and N application can enhance profit and nitrogen use in maize production.
