Abstract:Investigations were carried out on the effect of the activity ratio of potassium to calcium and magnesium  /></span>in the nutrient solution applied by drip irrigation on the growth and nutrient uptake of lettuce (<i>Lactuca sativa</i> var. Great Lakes 366) grown on Tottori sand dune soil.</p> The <span class= /></span> of the soil solution was influenced by that of the nutrient solution. Calcium nutrition of lettuce was not influenced by the <span class= /></span> in the soil solution. However, the magnesium nutrition was improved at a low activity ratio, which resulted in the alleviation of the physiological injury.</td>
