%X In the high Andes, the traditional rotation is two or three years cropping with potatoes and cereals after 5 to 10 years of fallow. In the Bolivian Altiplano, the balance of available soil nitrogen (N) was monitored during 2 years of cultivation after 3 years rotation. Potatoes or barley were planted in the second year. Fertilization with sheep dung was only applied for potato cropping. The dynamics of decomposition and N-release of the amendment and the plant residues were measured using litterbag incubation in the field. Using te N-release rates provided by the litterbag experiment, we modeled the fate of the mineralizable N originating from the sheep dung and the potato residues decomposition of a 2-year succession to assess if the N supply from fertilization covered the pant demand.
