96 percent and the same treatment on a loamy fine sand at
Webster increased the yield 172 percent when compared with
clover which was not re-treated.
 For maintaining established clover or lespedeza pastures the
following fertilizers may be used:

 1. 300 to 500 pounds per acre of 0-14-10 or 0-10-10 fertilizer or
 Sits equivalent applied annually.
 2. If high rates of rock phosphate or colloidal phosphate have
 been used for establishing clovers or lespedeza, 80 to 160 pounds
 per acre of 0-8-24 fertilizer should be applied annually.
 The 0-8-24 fertilizer will furnish readily available phosphorus
 and also supply sulfur in case of its deficiency.
 For clovers the fertilizers should be applied in the fall (Novem-
 ber) and for lespedeza in early spring.
 One ton of lime may be added every 3 to 5 years.
