Dissipation and Sorption of Urea on Eburru Soils in Kenya
Dissipation and sorption of urea on Eburru soils in Kenya was done using kinetic studies which indicated that 35.00% of urea was adsorbed in the Eburru soil matrix nanopores within an equilibration of 24 hours. The presence of urea molecules in the loaded soil samples was further confirmed by XRD, FTIR and SEM characterization. Controlled urea release behavior of Eburru loaded soil samples was also determined to be 82.8% in water and 74.2% in Kikuyu soil.
