Urea hydrolysis in a brown soil: effect of hydroquinone
1992
Xiaoyan, Z. | Likai, Z. | Guanyun, W.
The inhibition of urea hydrolysis in a brown soil by hydroquinone lasted for <10 days under laboratory incubation conditions. Soil ammonium-N content in the hydroquinone treatments was higher than that of the control during the middle and later stages of incubation and the increased amounts were positively related to the concentrations of hydroquinone. A pot trial with N-labelled urea showed that in the presence of the applied hydroquinone, wheat plants absorbed more soil-N and urea-N during the early and later growth stages respectively, and also, the rate of hydroquinone application was a key factor affecting wheat yield.
