Abstract
Proceeding from three previously derived expressions for the intensity of nitrification in soil as a function of time (logΣN=K.logt+q), as a function of incubation moisture (logΣN=A.pF i+B), as a function of initial moisture (logΣN=C.pF v+D), it was shown that the nitrification intensity as a function of time and of moisture can be expressed by the bilinear function log ΣN=a.pF i.logT+b.pF i+c.logt+d; as a function of time and of initial moisture by the bilinear function logΣ=N=a.pF v.logt+b.pF v+c.logt+d; as a function of initial and incubation moisture by the bilinear function log ΣN=a.pF ipF v+b.pF i+c.pF v+d. The intensity of nitrification as a function of time, incubation moisture and initial moisture may be expressed by the multilinear function log ΣN=a.pF i.pF v.logt+b.pF i.pF v+c.pF i.logt+d.pF v.logt+e .pF i+f.pF v=g.logt+h. This function is valid for all the incubation moistures lying between pF i 3.0 and 4.0 and for all initial moistures between 3.5 and 5.9 provided that the incubation temperature remains constant.
