Abstract – The objective of this work was to evaluate the losses of N-NH3 by
volatilization and the agronomic efficiency of a mixture of urea with natural
zeolite, as topdressing fertilization, in an area for the commercial production
of roses (Rosa spp.). The treatments were: two rates of urea (60 and 120 kg ha-1),
with and without zeolite. The N sources were applied directly to soil surface,
and volatilization was determined using a free semi-open static chamber. The
quantitative and qualitative variables of the collected flower stems were used
to determine the agronomical efficiency of the fertilizers. The zeolite mixture
reduces N-NH3 losses in 30%, compared with the commercial urea fertilizer,
and shows a higher agronomic efficiency, resulting in an increase of 25 dozen
of flower stems per each kilogram of N applied.

Resumo − O objetivo deste trabalho foi avaliar as perdas de N-NH3 por
volatilização e a eficiência agronômica de mistura de ureia com zeólita
natural, como adubação de cobertura, em área de produção comercial de rosas
(Rosa spp.). Os tratamentos foram: duas doses de ureia (60 e 120 kg ha-1),
com e sem zeólitas. As fontes nitrogenadas foram aplicadas na superfície
do solo, e a volatilização foi determinada com uso de câmara semiaberta
livre estática. As variáveis quantitativas e qualitativas das hastes florais
colhidas foram utilizadas para determinação da eficiência agronômica dos
fertilizantes. A mistura com zeólitas diminuiu as perdas de N-NH3 em 30%,
em comparação ao fertilizante ureia comercial, e mostra maior eficiência
agronômica, tendo resultado em incremento de 25 dúzias de hastes florais por
quilograma de N aplicado.
