Fertilizers are classified in several ways. They can be classified based on having only one nutrient (for example potassium, phosphorus or nitrogen), in which case they are called “direct fertilizer”. “Integrated fertilizers” contain two or more different nutrients. Fertilizers are sometimes classified based on being natural (organic) and chemical (non-organic). Inorganic or chemical fertilizers remove carbonaceous substances other than urea. Natural or organic fertilizers are usually plants (recycled) or taken from animals. Inorganic fertilizers are usually called chemical fertilizer Minerals because they require several chemical processes to prepare.

Microelements and some are also elements of low consumption elements of the plant (microelements).
High consumption elements (macro) include: nitrogen – phosphorus – potash – calcium – magnesium
Low consumption elements (micro) including: iron – zinc – manganese – copper – bar
types of fertilizers that have all of the above elements together and in a proportionate proportion are called complete fertilizers.
Different plants will need the above fertilizers according to the need and according to the test results of leaves and soil.
The chemical composition and purity of different fertilizers containing an element are very different. These differences have a significant impact on the consumption, distribution, fertilization time and effectiveness of fertilizers. Therefore, sufficient knowledge of the types of chemical fertilizers before selection or consumption is necessary.
Nitrogen fertilizers Because it has a negative charge, it does not absorb soil colloids and is subject to leaching from the soil. But because it has a positive charge, it absorbs soil colloids. Urea is the most common nitrogen fertilizer in Iran. Urea is considered an organic compound and can be absorbed by the plant in the same way. Urea solution is also used in foliar spraying of plant leaves.
Ammonium urate nitrate can be given to the soil before planting or as a road and after the plant has grown a little. Ammonium sulfate contains 24% sulfur in addition to nitrogen. Ammonium hydrate, which is obtained by dissolving ammonia in water, is placed under a layer of soil by special syringes before planting.
Calcium nitrate and potassium nitrate have a low nitrogen content and are less commonly used as a source of nitrogen fertilizer in the soil. These fertilizers are often used in food solutions as sources of calcium or potassium.

The percentage of phosphorus oxide is mentioned. Phosphoric acid, which is obtained from the decomposition of soil organic matter, can be absorbed by the plant, but is not used as a chemical fertilizer. Most of the phosphorus list of chemical fertilizers given to the soil. It is stabilized by calcium in alkaline soils and by iron and aluminum in acidic soils. Usually, the phosphorus fertilizer given to the soil remains absorbable in the first year and a small part can be absorbed by the plant in the coming years. Depending on the soil and the amount of phosphorus fertilizer used.
Because the amount of solubility and movement of phosphorus fertilizer in the soil is very limited, phosphorus fertilizers should be applied to the soil before planting and placed directly in the root development zone. The maximum phosphorus solution is observed at pH 6 to 6.5. Therefore, delivering soil pH to these limits can be effective in increasing solubility and phosphorus absorption. Soil pH can be changed in acidic soils by adding lime and in alkaline soils by adding sulfur or acidic fertilizers. Consumption of large amounts of animal manure can also be beneficial in reducing soil pH. The solubility of phosphorus fertilizers also varies.
