The objective of this work was to quantify the losses of N from the soil-plant system, in the cane plant and sugar cane ratoon-cycle. Two experiments were carried out in 220 L-pots filled with sandy soil. In the experiment with cane plant two factors were studied: two types of sugar cane crop residues incorporated in the soil and four doses of N applied as urea. In the experiment with sugar cane ratoon two forms of urea application on soil surface were studied: over the straw (trash) or uncovered soil, or at a depth of 15 cm, and two potassium sources: KCl or vinasse. Urea labeled with 15N was used in both experiments. The experimental design was randomized blocks, with three replications. In the cane plant experiment, 12% of the N-urea app...
