Summary
This paper presents an overview of zero liquid discharge technologies and practices applicable to soilless greenhouse horticulture. The work synthesises solutions for recirculating irrigation systems designed to minimise or eliminate nutrient-laden drainage discharge, thereby reducing water consumption and environmental contamination whilst maintaining horticultural productivity. The paper appears to draw on multi-institutional expertise to evaluate technical and agronomic feasibility of closed-loop soilless systems.
Regional applicability
The findings are directly applicable to intensive greenhouse horticulture in the United Kingdom, where water scarcity and environmental regulation of farm runoff are increasingly pressing concerns. Soilless systems are common in UK protected horticulture, and ZLD approaches align with current policy drivers around water efficiency and nutrient pollution reduction.
Key measures
Water use efficiency, liquid discharge volumes, production outcomes in ZLD systems
Outcomes reported
The paper addresses solutions for implementing zero liquid discharge (ZLD) systems in soilless greenhouse production to reduce water consumption and environmental impact while maintaining crop yield and quality.
