The aim of this review was to discuss the transition from traditional irrigation to fertigation using reclaimed wastewater in countries with moderate climate. In most European countries there are no regulations on waste water reuse and on the other hand there are countries where regulations are very strict. An important aspect is to standardize the restrictions, which would minimize uncontrolled use of wastewater for fertigation. Wastewater is a source of plant nutrients and organic matter, but can be contaminated with chemicals and pathogens, which in turn can lead to secondary environmental pollution. The reuse of recovered wastewater may require modification of the wastewater treatment process line or construction of stabilization tanks at farms. In both cases, it is necessary to set up initial installations in real systems in order to develop principles for irrigation with reclaimed wastewater for soil and temperate climate conditions. The additional treatment steps required are also associated with large investments, but could reduce fertilization costs and, more importantly, improve the environmental situation. The current scale of fertilizer application does not allow conventional fertilization to fulfill global demand. The introduction of such a solution is a step towards the practical application of circular economy and sustainable crop production. The paper discusses a challenges related with implementation of transition from conventional irrigation to fertigation with reclaimed wastewater in moderate climate countries. A special focus to providing fertilizer nutrients in terms of required doses was undertaken.

这篇综述的目的是讨论在气候温和的国家从传统灌溉到使用再生废水的施肥的过渡。在大多数欧洲国家，没有关于废水回用的规定，另一方面，有些国家的规定非常严格。重要的方面是使限制标准化，这将最大程度地减少灌溉施肥过程中不受控制的使用。废水是植物养分和有机物质的来源，但会被化学物质和病原体污染，进而会导致二次环境污染。回收的废水的再利用可能需要修改废水处理工艺线或在农场建造稳定罐。在这两种情况下 有必要在实际系统中设置初始安装，以开发用于土壤和温带气候条件的再生废水灌溉的原理。所需的额外处理步骤也需要大量投资，但可以降低施肥成本，更重要的是，可以改善环境状况。当前的肥料施用规模不允许常规肥料满足全球需求。引入这种解决方案是朝着循环经济和可持续作物生产的实际应用迈出的一步。本文讨论了在温和气候国家实施从常规灌溉到施肥再生废水过渡的相关挑战。
