摘要:
Urea fertilisers are often applied to soil with cereal residues on the surface. Although the urease properties of soils have been investigated, the urease activities associated with cereal residues have not been thoroughly studied. Two experiments were performed to develop an acceptable urease assay for cereal residues, and to determine the effect of field exposure and concomitant saprophytic colonization on urease levels.
