Summary

1,4-Naphthoquinone; 2-methyl-1,4-napthoquinone; 2,3-dichlorohydroquinone; 4,6-di-tert.butyl-o-benzoquinone; 4,6-di-tert.butylpyrocatechol and 4-tert.butylpyrocatechol at concentrations of 10 and 20 ppm inhibit mineralization of urea N by reducing urease activity and/or nitrification in soils. Coating of urea with these chemicals was more effective than direct application to the soil. There was no adverse effect of any of the chemicals either on germination or on the growth of wheat plants at concentrations of 20 and 50 ppm added to soil.
