-A lysimeter experiment was carried out with sugarcane aiming to evaluate the leaching of nitrogen derived from either urea ( was also evaluated. The experiment was a factorial 2x4. The influencing factors were: firstly, the differential addition of two kinds of sugarcane remains to the soil, simulating conditions of caneplantation renewal after the cane crop harvest, with and without previous straw removal by burning; secondly, four doses of N: 0, 30, 60, and 90 kg ha . O experimento foi um fatorial 2x4. Os fatores foram: 1) adição diferenciada de dois tipos de restos culturais ao solo, simulando condições de reforma de canavial após a colheita da cana, com ou sem prévia despalha a fogo; 2) quatro doses de N: 0, 30, 60 e 90 kg ha
