Improving tree growth on poor and medium sites through the use of legumes. Annual report, February 14, 1980-September 1, 1980
Progress is reported on research to improve the productivity of poor land through the use of legumes and limited fertilization. Two sites, a low productivity deep sand and a moderately productive loamy soil were planted to pine, fertilized, and sown to legumes in the winter and spring of 1980. Phosphorus and K were applied to plots of loblolly pine on the loamy soil and to loblolly and Choctawhatchee sand pines on the deep sand. Virgata, sericea, and bicolor lespedezas were sown on disked strips on the deep sand, with Kobe being added on the loam soil. By late July 1980, all legumes were successfully established. Results showed disked strips on the deep sand had nine legume seedlings per .09 m/sup 2/ area and the loamy soil had 14. Loblolly pine had 75% survival on the loamy soil, and 85% on the deep sand. Sand pine on the deep sand had 82% survival. The difference in survival due to site was significant at the 5% level. Fertilizer and legume treatments had no effect on tree survival.
