Growth and quality of tomato plants grown in sand and perlite by the use of geothermal water

Summary

This early 2000s trial investigated the viability of using geothermal water for intensive tomato production in soilless substrates, comparing sand and perlite as growing media. The work contributes to understanding low-input, thermally-sustainable horticultural practices in Mediterranean or geothermal-rich regions, potentially reducing freshwater demand and production costs for protected cultivation. No abstract was available; specific findings regarding growth and quality outcomes cannot be confirmed without access to the full paper.

Regional applicability

Direct applicability to the United Kingdom would be limited, as the study was conducted in a geothermal region (likely North Africa or Mediterranean), which differs significantly from UK climate and available thermal resources. However, the substrate comparison and soilless cultivation methodology may be transferable to UK greenhouse horticulture, particularly for winter heating scenarios or regions with local geothermal potential.

Key measures

Plant growth metrics (height, biomass, yield), fruit quality parameters (likely including size, soluble solids, and nutrient content), substrate performance in sand and perlite systems

Outcomes reported

The study evaluated growth performance and fruit quality characteristics of tomato plants cultivated in sand and perlite substrates irrigated with geothermal water. Metrics likely included yield, plant biomass, and quality parameters such as fruit size, soluble solids content, or nutrient composition.
