Fate of [14C]hydroquinone and [15N]urea in a soil-rice system: A pot trial

摘要: Abstract [ 15 N]urea and 14 C]hydroquinone were applied to brown soil (Agrodolf) at rates of 61.33 μg, N g −1 533.2 ng hydroquinone respectively in a rice pot trial. Total C-materials isolated determined. The results showed the plant absorbed 0.25% added this, only 34 47 − existed form refined grain straw, respectively. Most had been degraded or converted other forms tissues. In soil, decomposition rate was found be 86.6% about 58% could not detected; it contained 72 (average) after 3 months growth, much lower than its Multimedia Environmental Goal. effects on promotion yield urea efficiency observed this trial due special experimental conditions. It is concluded that applying appropriate concentration with as urease inhibitor will produce harmful human health environment.
