Special Issue Information
Dear Colleagues,
Water shortages and fertilizer pollution are important factors that affect agricultural production. In recent years, with the intensification of global climate change, the balance between water, fertilizer, and climate has become an important issue that must be considered by every agricultural producer. According to a report by the World Resources Institute and the Food and Agriculture Organization of the United Nations, 60% of irrigated agriculture is under extreme water stress on the global scale, 1.2 billion people in agricultural areas are at risk of water scarcity and acute water scarcity, and nearly 1.0 billion hectares of agricultural land are affected by this. Consequently, improving irrigation water use efficiency has become the primary issue for ensuring national food security. The popularization and application of fertilizer is an important means to promote an increase in agricultural production; according to a research report by QYResearch, the worth of the global fertilizer market is estimated to soon reach USD 122.08 billion, and it is expected that, by 2030, it will be valued at USD 148.08 billion, with a compound annual growth rate (CAGR) of 4.28%. However, the overuse of fertilizers also brings great environmental pressures, such as soil degradation, water pollution, and greenhouse gas emissions. Climate change will lead to a series of problems, e.g., water scarcity and uneven distribution, increased soil water evaporation, changes in crop water requirements, and a decline in irrigation water quality. Therefore, the high-quality development of crop tillage systems urgently needs to realize the precise regulation of irrigation and fertilizer under future climate change scenarios. This Special Issue will cover a wide range of areas regarding the relationship of crops with irrigation, fertilizer, and climate change, with the aim of creating a favorable water–fertilizer environment for the optimization of crop tillage systems.
