Nitrogen plays an important role in the process of plant growth and development, as well as strengthening the crop and increasing its weight, and its use should be used several times according to the farm’s fertilizer management program.
Also, cocoly fertilizer in Pakistan and along with them decomposed animal manures can meet the plant’s nitrogen requirement to some extent.
Some of the most widely used chemical fertilizers with nitrogen include: nitrate, ammonium sulfate, urea and NPK fertilizers.
Phosphorus fertilizer: We can use phosphorus fertilizers in areas where the amount of phosphorus in the soil is lower than the optimal level.
Phosphorus plays a role in the process of rooting and flowering in plants.
Biofertilizers can also be used to supply phosphorus needed by the plant.
The important point in the use of phosphorus fertilizers is that excessive use of phosphorus fertilizers leads to disturbances in the absorption of zinc and iron elements in the plant.
Monoammonium phosphate and diammonium phosphate are phosphorus fertilizers.
Potassium affects the quality, size and appearance of the fruit. Increases drought tolerance by increasing root growth.
It also plays a role in photosynthesis and food production.
Potassium chloride, potassium sulfate, potassium nitrate, etc. are among the types of potassium fertilizers.
The fertilizer that contains all three macronutrients of nitrogen, potassium and phosphorus is called complete fertilizer or NPk.
This fertilizer helps the growth of all plants by providing the mentioned elements and is considered one of the most widely used types of fertilizer.
NPK fertilizer has three numbers, each of which indicates the presence ratio of each element.
In this series of numbers, the first number corresponds to the amount of nitrogen, the second number indicates the content of phosphorus and the third number indicates the amount of potassium.
For example, the fertilizer named 20-15-10 consists of 20% nitrogen, 15% phosphorus and 10% potassium.
