In recent years, my state for the black wattle has been a lot of cultivation, and set up a base in order to clarify the savannas seedlings on fertilizer needs in order to formulate reasonable fertilization measures to guide the production of black wattle. We from 1987 to 1988, for two consecutive years of nitrogen, phosphorus, potassium and compound fertilizer four kinds of fertilizer, and different doses of compound fertilizer on the growth of young Wattle tree experiment.
