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. |
