Due to the lack of scientific knowledge for the use of substrate and best fertilizing method in the growth of Araucaria excelsa, it is crucially important to find the most appropriate planting substrate and fertilizing method. The effect of conventional fertilizing method and the application of Fe nanofertilizer were studied on the growth of A. excelsa in which six fertilizing methods and three...
