Chemical fertilizer
Chemical fertilizer differs in terms of the type of elements it contains and the proportion of each
The plant's need for fertilizer varies depending on the condition of the soil and the type of plant
For example, nitrogen fertilization is needed by plants more than other elements, especially plants from which grass is taken Or leaf like mint, basil and marjoram
As well as plants that contain alkali, such as sugar, belladonna, and Datura, as it works to increase the active substance in these plants
nitrogenous fertilizers
such as ammonia sulfate and contain 20% nitrogen, sodium nitrate 15% nitrogen, calcium nitrate 15% nitrogen, as well as calcium nitrate in addition to urea 46% nitrogen and ammonium nitrate 33% nitrogen
phosphate fertilizers
they are important in stimulating flowering as well as fruiting As well as increasing the essential oil in the leaves and seeds
It also has a role in the amount of nitrogen absorbed by the plant. The plant can obtain it from poultry waste, or from monocalcium superphosphate 16% and di-calcium superphosphate 32%.
for potassium fertilizers
it has an effective role in regulating vital processes, absorbing nitrogen, and regulating the water content in the cell. Potassium also increases the hardness of the cell wall and is involved in the synthesis of protein and enzymes.
Therefore, the effect of potassium appears clearly in plants that store carbohydrates, such as persimmons, liquorice, maghat, and orchids
Among the sources that contain potassium, such as sheep waste, sebum, sawdust, and plant leaf powder
As for chemical fertilizers that contain potassium, such as potassium nitrate 44%, potassium phosphate 34%, potassium sulfate 48-50%, and potassium chloride 50%.
