Webb1 jan. 1991 · Rachhpal-Singh and Nye (1984) studied the effect of up to 10 M urca-N in the soil solution on the rate of urea hydrolysis in a Begbroke soil. They found that the rate of urea hydrolysis increased with an increase in urea concentration until a maximum was reached; at higher urea concentrations, the rate of hydrolysis decreased.
