Slow-release urea fertilisers have been shown to present acceptable values for plant yield and mitigate the harmful efect of
soil emission gases. This study synthesises a slow-release fertiliser containing fumed-nanosilica, nanofbrillated cellulose as
well as sodium alginate as a urea carrier to analyse the growth parameters of Eucalyptus urograndis seedlings and potential
emission of soil gases, N2O, CH4, CO2 and ammonia volatilisation. The developed supraparticles, arranged layered nanopar-
ticle structure, presented a decrease in the normal nitrogen content of urea of 19%, which is attributed to the binding of this
element. A good electrostatic interaction between the elements was confrmed by the FTIR with 20% of nitrogen content from
its chemical composition and an increase in thermal degradation of the main components when synthesised. The profle of
urea release presented to be as frst-order with 85% of this compound was released only after 60 days. These characteristics
led to statistically increased growth of Eucalyptus seedlings compared to the controls, which improves with higher dosages
of urea. Values of biomass and characteristics of the plant were used for principal component analysis which resulted in good
cluster formation based on the upward concentration of urea added to the plant. Nevertheless, fux gases were statistically
higher for certain time periods on lower urea particle concentration, while increased concentration presented N2O emissions
within standard rates with no signifcant variation in the other measured gases, which was attributed to the soil microbial
targeted consumption. Therefore, this material can be benefcial in the agriculture industry. MenosSlow-release urea fertilisers have been shown to present acceptable values for plant yield and mitigate the harmful efect of
