Agriculture is the primary driver of growth in most developing countries, providing rural residents with a huge number of job opportunities and supporting them in reaching their food and nutrition security. Film farming (FF) is a novel agricultural procedure developed in Japan enabling soil-less crop cultivation while cutting water use dramatically. FF has the potential to be integrated into vertical farming systems in order to increase water efficiency and food safety. This, on the other hand, relies on possible increases in yield and plant quality to balance the additional expense of film farming by increasing sales volume and price. Polymer-based controlled-release fertilizer nano-formulations are being developed to improve fertilizer use efficiency and reduce losses due to leaching, runoff, and volatilization. These fertilizer formulations ensure that nutrients are released at a very slow pace over a lengthy period of time, preventing nutrient losses and ensuring optimal nutrient availability in the rhizosphere. This editorial discusses the advantages of film farming for water conservation and nutrient release, as well as their importance in increasing production and quality. More research into the intersection of nanomaterials, soil-less farming, and microgreen gardening will assist to improve food supply sustainability.
