Effect of the herbicide trifluralin on nitrogen – fixation in rhizobium
and azotobacter and on nitrification
|
|
Abstract: Nodulation and growth of cowpea were inhibited upon the application of the trifluralin on the day of planting and were stimulated when the herbicide was applied 27 days before planting . Azotobacter was not affected by the trifluralin . Nitrifiers were very sensitive to the herbicide . Disappearance of trifluralin from the soil was rapid when the concentration of the herbicide was low . One litre / feddan (hectare = 2.38 feddan ) almost disappeared within 27 days . After 27 days, 16 and 27 % of trifluralin remained from 3 and 6 litres / feddan , respectively .
