Indoor cultivation experiment and plot field experiment were conducted to study the effect of lignosulfonates on urea nitrogen transformation in soil and the mechanism of controlling nitrate pollution in vegetable. Results showed that lignosulfonates behaved inhibition effect on urea hydrolysis
The search of inhibitors of the myrosinase enzyme and also enzymes able to transform the glucosinolates into non-toxic combinations has been carried out among the water extracts of the plants row. The inhibitor activity of the water extract of Arctostaphylos uva-ursi and its foresee acting
