It can be noted in the table that low potassium level was mora prevalent 

 this year than the two previous seasons. However, since the samples are not from 

 the same orchards each year, it is not feasible to interpret any trends. For 

 example, one might say the reason for the increase in percentage of samples with 

 low potassium in 1962 might be due to dry weather. On the other hand, rainfall 

 was ample in 1959 and low potassium levels were quite prevalent. 



Leaf samples were obtained from 40 orchards ir 1962. In twenty-three of 

 these orchards growers used a complete fertilizer but 16 growers used no nitrogen 

 in some blocks. Some growers are not using nitrogen in an attempt to lower the 

 nitrogen level in the trees and thereby increase fruit firmness and color. 

 Growers attempting to lower the nitrogen level in their orchards should realize 

 that it may take two or more years for this to occur following reduced rates of 

 nitrogen application. On the other hand, a moderate nitrogen level should be 

 maintained.. Leaf analyses should be requested from county agents in order to 

 follow the effect of the fertilizer program adjustments.
