Abstract

The effects of anthraquinones and some other quinonoid and phenolic compounds on mineralization of urea N in soils were studied by estimating the influence on urease activity and nitrification. Anthraquinones did not affect the mineralization of urea N but 1,4-naphthoquinone; 2-methyl-1, 4-naphthoquinone; 2-3-dichlorohydroquinone; 4,6-di-tert. butyl-o-benzoquinone; 4-tert. butylpyrocatechol and 4,6-di-tert. butylpyrocatechol inhibited urease activity and nitrification. The hydrolysis of urea (100 ppm) was not prevented by partial reduction in urease activity. The effective substances also inhibited dehydrogenase activity.
