Resumen
Descripción
Tomato plants were grown in pots containing sand and fed continuously by drip irrigation with nutrient solutions made from either analytical-grade salts or commercial fertilizers (having the same concentrations of macro- and microelements in each case). Significantly higher P and Ca concentrations and significantly lower Cl concentrations were found in the aerial parts and roots of plants supplied with analytical-grade salts than in those supplied with commercial fertilizers. Fruit juice also contained significantly more P with the analytical-grade salts. The DWs of aerial parts and roots were significantly higher with the analytical-grade salts and yield was increased 3-fold compared with the commercial-fertilizer treatment. These differences were attributed to the greater purity and solubility of analytical grade salts.
