Although the earths atmosphere is composed of 78% nitrogen (N2), it does not exist in a form that plants can take up nitrate (NO3) or ammonium (NH4+). Air contains about 20% oxygen. The correct diagnosis of the deficiency is important to correct the problem. report will provide information on soil deficiencies and will make recommendations Leaf colour will be a darker green and growth will be stunted. Correcting soil pH is the key to unlocking these nutrients.
