Fertilizers that have the sum of the above elements together and in proportion are called complete fertilizers.
Different plants will need the above fertilizers according to their needs and according to the results of leaf and soil tests.
The chemical composition and purity percentage of different fertilizers containing the same element are very different.
These differences have a very important effect on the use, method of spreading, fertilization time and effectiveness of fertilizers.
Therefore, sufficient knowledge of chemical fertilizers is necessary before choosing or using them.
Some of the chemical fertilizers are part of the high-use plant elements or macroelements, and some are part of the low-use plant elements (microelements).
Macro elements include nitrogen, phosphorus, potassium, calcium and magnesium.
