Summary
Laboratory experiments were carried out with alluvial sandy loam soil to study the effect of simazine and atrazine herbicides at four levels (0.5, 1.0, 1.5 and 2.0 kg/ha) on the mineralization of nitrogen (ammoniacal and nitrate production) from fertilizer urea and sludge sources. The herbicides stimulated nitrate production. No specific trend in total mineralized nitrogen, ammoniacal and nitrate nitrogen was observed by varying the levels of herbicides. Mineralization of total nitrogen (ammoniacal and nitrate nitrogen) in presence of simazine and atrazine from the different sources in the descending order was:
Urea > Sludge + Urea > Sludge > No Nitrogen.
