Abstract
Net mineralizable sulphate, extractable with 0.15% CaCl2, was measured on two soils incubated with a variety of nitrogen sources and rates. Significant effects of source, rate and of interactions were observed, but the responses of the two soils were quite dissimilar. Both net mineralization and net immobilization were encountered.
