Normally, nitrogenous fertilizers contain fast release nitrogen which is quickly absorbed by the plant roots or otherwise leached away from the rhizosphere. So, it is always necessary to apply nitrogen to the soil repeatedly which increases the costs and also labor works. But in Mr. Maestro N21, thanks to DMPP technology, conversion of ammonium to nitric form is slowed down so plants will absorb N from soil gradually based on their needs. DMPP is an inhibitor of the nitrification process; meaning that it reduces the speed of conversion of ammonium to nitric form. Ammonium is less sensitive to leaching and is more effectively utilized by plants. So, Mr. Maestro N21 increases the efficiency of nitrogen use by plants.
