Adding lime increases the pH, thus countering the competition between protons. Because of a time schedule a grower needs to apply urea in November that is not needed until March. He can add nitropyrin with the urea. This will stop the Nitrosomonus bacteria from converting the NH 4 to NO 3 . NH 4 is fairly stable in soil if it is not converted to NO 3 .
Research shows that higher uptake rates can occur at night when the stomates are closed.
The inside of the stomates are covered with a cuticular wax layer. The leaf tissue base around the trichomes have thinner cuticle layers which facilitates more uptake. Jason Gray 14. The whiptail symptoms develop as a result of Mo deficiency. Mo is a cofactor of the nitrate reductase enzyme needed to reduce the NO 3 - .
