摘要: Abstract Gross rates of ammonification were measured over 9 days by 15N isotope dilution techniques allied to a mathematical model in an Orthic Ferralsol from Kenya. Rates mineralization soils conditioned for 24 at different constant gravimetric moisture contents increased 0.08 μg−1 Ng−1 d−1 both and nitrification −5.91 MPa 2.12μg Ng−1d−1 −0.063 MPa. In soil which had been constantly then wetted −0.42 MPa, gross immediately stimulated. Wetting no effect on days.
