Long-Term Effects of Nitrogen Fertilization on Giant Reed (Arundo Donax L.) Biomass Productivity

W. Zegada-Lizarazu, G. Pritoni & A. Monti
Proper soil fertility maintenance is an issue of significant importance because of its impacts on crop productivity, production costs, and on the environment. The objective of the present study was to determine the long­term effects (13 years) of several nitrogen fertilization doses on the aboveground biomass production of giant reed. A local ecotype of giant reed was planted in 1997 in Bologna (Italy) at a density of one plant per square meter. Every year, starting...
