Conteúdo: | We report the first results obtained with a Brazilian sedimentary zeolite (hereafter called the zeolite concentrate, ZC) to reduce ammonia volatilization - loss of the nitrogen nutrient - in tropical farms. Preliminary laboratory tests were made with both ammonium sulfate and urea into ZC. The reported field tests - obtained in rose cultivations - show a significant effect of the use of urea mixed with ZC on the stem growth of the rose buds. In the laboratory tests, the observations of the retention of ammonia by ZC were done using the photoacoustic set-up described in this work. The report data were obtained at temperatures of 25 and 60°C, simulating typical tropical weather temperatures.
