Comments

Peaches - Final remark. For establishing new orchards, apply lime and P and K fertilizer as recommended and turn to a depth of 12 to 16 inches, then repeat the application and disk into the topsoil. Broadcast 20 to 25 pounds Zn (50 to 70 pounds 36% Zn sulfate) per acre and disk into topsoil when establishing new plantings. No soil applications of zinc are usually needed on old orchard or crop land. Maintain soil pH at about 6.5 by reliming as needed by soil test.

For annual maintenance apply P and K fertilizer as recommended. For the first and second leaf apply 0.08 pound N (four ounces ammonium nitrate or equivalent) per tree per year of age about February 15, then repeat two or three times at six-week intervals beginning at initiation of new growth. In third leaf apply 0.6 pound N (1.75 pounds ammonium nitrate) per tree, in fourth leaf apply 0.8 pound N (2.33 pounds ammonium nitrate), and in fifth leaf or older apply one pound N (three pounds ammonium nitrate) per tree. Beginning in third leaf apply two-thirds of the N in February and one-third of the N after harvest.
