✦ Synopsis

A laboratory study was made of the influence of the sulpha drugs sulphathiazole, sulphanilamide, sulphapyridine, sulphaguanidine, sulphadiazineand sulphadiamidine on nitrification of urea applied to a sandy clay loam soil of pH 7.8. Sulphathiazole applied at 2 ppm inhibited the nitrification of urea most effectively. Sulphadiazine and sulphadiamidine were also found to have nitrification inhibitory properties and need further testing. About 14% of applied urea N accumulated as nitrites after 1 week of incubation. Application of sulpha drugs along with urea reduced nitrite accumulation.
