This editorial introduces our Special Issue entitled "Improving Fertilizer Use Efficiency-Methods and Strategies for the Future". The fertilizer use efficiency (FUE) is a measure of the potential of an applied fertilizer to increase the productivity and utilization of the nutrients present in the soil/plant system. FUE indices are mainly used to assess the effectiveness of nitrogen (N), phosphorus (P), and potassium (K) fertilization. This is due to the low efficiency of use of NPK fertilizers, their environmental side effects and also, in relation to P, limited natural resources. The FUE is the result of a series of interactions between the plant genotype and the environment, including both abiotic and biotic factors. A full recognition of these factors is the basis for proper fertilization in farming practice, aimed at maximizing the FUE. This Special Issue focuses on some key topics in crop fertilization. Due to specific goals, they can be grouped as follows: removing factors that limit the nutrient uptake of plants; improving and/or maintaining an adequate soil fertility; the precise determination of fertilizer doses and application dates; foliar application; the use of innovative fertilizers; and the adoption of efficient genotypes. The most important nutrient in crop production is N. Hence, most scientific research focuses on improving the nitrogen use efficiency (NUE). Obtaining high NUE values is possible, but only if the plants are well supplied with nitrogen-supporting nutrients. In this Special Issue, particular attention is paid to improving the plant supply with P and K.
本社论介绍了我们的特刊，题为“提高肥料利用效率——未来的方法和策略”。肥料利用效率（FUE）是衡量施用肥料增加土壤/植物系统中养分生产力和利用率潜力的指标。FUE指数主要用于评估氮（N）、磷（P）和钾（K）施肥的有效性。这是由于氮磷钾肥料的利用效率低、它们对环境的副作用，以及就磷而言，自然资源有限。FUE是植物基因型与环境之间一系列相互作用的结果，包括非生物和生物因素。充分认识这些因素是农业实践中合理施肥的基础，目的是使FUE最大化。本特刊关注作物施肥中的一些关键主题。由于特定目标，它们可分为以下几类：消除限制植物养分吸收的因素；改善和/或维持充足的土壤肥力；精确确定肥料用量和施用日期；叶面施肥；使用创新肥料；以及采用高效基因型。作物生产中最重要的养分是氮。因此，大多数科学研究都集中在提高氮利用效率（NUE）上。只有在植物得到充足的氮支持养分供应时，才有可能获得高NUE值。在本特刊中，特别关注改善植物对磷和钾的供应。
