oa Journal of Applied Science in Southern Africa - Effects of organic and inorganic nitrogen fertilizer on maize (Zea mays L.) nitrogen uptake and nitrate leaching measured in field lysimeters

Volume 8, Issue 1

Maize (Zea mays L.) production in the smallholder farming areas of Zimbabwe is based on both organic and inorganic nutrient sources. A study was conducted to determine the effect of cattle manure, N fertiliser, and their combinations on nitrate concentration in leachate leaving the root zone and to establish N fertilisation levels which minimise N leaching. Maize was grown for two seasons (1996/97 and 1997/98) in field lysimeters repacked with a coarse-grained sandy soil. Average leachate volumes over the two seasons were similar between different treatments, and ranged from 388 to 418 mm yr-1.
