Tomato plants were grown in hydroponics using pelleted fly and heavy ash as substrates. The water stability of the substrates and their ability in a nutrient, solution to sorb or desorb ions have been studied. Both substrates showed a satisfactory stability to water treatments. Interactions between the nutrient solution and the substrates did not influence the ion uptake by tomato plants nor plant growth and productivity.

Abstract
Tomato plants were grown in hydroponics using pelleted fly and heavy ash as substrates. The water stability of the substrates and their ability in a nutrient, solution to sorb or desorb ions have been studied. Both substrates showed a satisfactory stability to water treatments. Interactions between the nutrient solution and the substrates did not influence the ion uptake by tomato plants nor plant growth and productivity.File in questo prodotto:
