Calphos Stimulates Growth of Newly Planted Loblolly Pines

One-year-old loblolly pine seedlings were barplanted in furrowed and unfurrowed rows in an open field in eastern Texas. Three or 6 ounces of calphos were placed in planting holes. One week after planting, 1 ounce of 60 percent muriate of potash and 1.5 ounces of 40 percent ammonium sulphate were spread on the soil surface in a 12-inch radius around each seedling. Unfertilized seedlings, planted in the furrowed and unfurrowed rows, served as controls.
