Improving Fertilizer Use Efficient Method and Strategies: A Sustainable Approach for Future

The potential of an applied fertilizer to boost the production and utilization of the nutrients present in the soil/plant system is measured by the fertilizer usage efficiency (FUE). The primary purpose of FUE indicators is to evaluate how well fertilization with nitrogen (N), phosphorus (P), and potassium (K) works. The low effectiveness of NPK fertilizers, their negative environmental effects, and the scarcity of natural resources in relation to P are the causes of this. The plant genotype and the environment, which includes both biotic and abiotic elements, interact to produce the FUE. The foundation for appropriate fertilization in agricultural practices, which aims to maximize the FUE, is a thorough understanding of these elements. A few important subjects in crop fertilization are the focus of this special issue. Owing to particular objectives, they can be categorized as follows: eliminating obstacles that prevent plants from absorbing nutrients; enhancing and/or preserving sufficient soil fertility; accurately calculating fertilizer dosages and application schedules; applying fertilizer topically; utilizing cutting-edge fertilizers; and implementing effective genotypes.
