Summary: Nutrition is a crucial factor in the growth and development of plants, particularly in terms of flowering. The process of flowering represents a transition from vegetative to reproductive stages, which requires nutrient consumption. Furthermore, nutrients such as nitrate act as signals that impact flowering. This review aims to enhance our understanding of how plant nutrition influences flowering by examining the relationships between nutrients (primarily nitrogen, phosphorus, and potassium) and the flowering process.

Summary: Substrate-grown crops in southern Spain make up 10% of intensive greenhouse horticulture, and their free-draining nature leads to significant nutrient loss in drainage, causing water contamination. This study examined two management approaches, ratio-based and uptake concentration-based, to reduce nutrient loss in drainage. Both strategies significantly reduced nutrient application, with ratio-based management reducing nutrient loss by 58-77% and uptake concentration-based management reducing it by 65-80%.

Summary: Nutrient use efficiency is crucial for increasing crop yield and quality while reducing fertilizer inputs and minimizing environmental damage. The study in Nepal showed that optimal amounts of nitrogen, phosphorus, and potassium significantly influenced wheat performance and nutrient efficiency. The study recommends specific nutrient levels for efficient nutrient management in wheat cultivation in the mid-hills of Nepal.

Summary: Overuse of chemical fertilizers has caused serious agricultural pollution. This study empirically analyzed the effect of farmland scale on fertilizer use from the perspective of nutrient elements, using micro-survey data from 1015 households in 5 provinces of China. The results showed that farmland scale had a significant negative impact on the nitrogen application rate from fertilizer, but no statistically significant impact on phosphorus or potassium application rates. The findings also revealed heterogeneity effects of farmland scale on nutrient element application rates.

Summary: The aim of this research was to identify the Boundary-Line Approach (B-LA) macro-nutrient optimum concentrations related to maximum yield and sufficiency ranges for Opuntia ficus-indica (L.) Miller variety Rojo Pelon. By analyzing four years' data of yield and macro-nutrient concentrations, the study found that the optimum concentrations of nitrogen, phosphorus, potassium, calcium, and magnesium, as well as sufficiency ranges, can be used as reference standards for maximizing yield per fructification cladode in this variety.

Summary: In this study, rhizo-box experiments were conducted to investigate the effects of nitrogen, phosphorus, and potassium co-application on rice. The results showed that the co-application improved root morphological and physiological characteristics, leading to increased nitrogen uptake and utilization efficiency.

Summary: The study developed an innovative nutrient recommendation approach, Nutrient Expert (NE), to optimize fertilizer use and improve crop yield, particularly for maize, wheat, and rice in China. NE outperformed current farmer practices and soil test-based fertilizer application in terms of yield improvement, profit increase, and reduced nitrogen losses and greenhouse gas emissions.

Summary: The study demonstrated that the use of Integrated Plant Nutrient System (IPNS) and different manures had positive effects on system productivity and nitrogen use efficiency in acidic and charland soils, with poultry manure biochar (PMB) and compost (OF) showing superior performance. These fertilizers can enhance soil properties and crop yield simultaneously.

Summary: This study investigated how stream communities respond to cumulative human impacts such as nutrient enrichment, showing that the effects of nutrient enrichment are conditional on upstream ecosystem conditions. Future assessments may need to consider the complexities related to environmental stressors when evaluating the impacts of human activities on stream ecosystems.

Summary: Our study found that leaf nitrogen resorption efficiency remained constant, while phosphorus and potassium resorption efficiency decreased with overstory succession. Additionally, we observed variations in leaf phosphorus levels between younger and older mixed stands compared to monocultures in Populus tremuloides.

Summary: The study found that phosphorus balance in cropping systems in the Vermelho River watershed in Upper Pantanal, Brazil, is positive, while in grazing systems it tends to be negative. The positive balance in cropping systems is mainly due to high phosphorus inputs from mineral fertilizers and high soil phosphorus sorbing capacities, while the negative balance in grazing systems is a result of nutrient removal without replenishment.

Summary: Dairy farms located in villages in China are an important sector in milk production. The development of village-based mixed livestock-crop systems can improve feed self-sufficiency, nutrient recycling, and reduce chemical fertilizer requirements, leading to increased crop productivity and benefit-cost ratio.
