Fertilizers are chemicals that are used to increase the fertility of seeds along with proper spraying. Fertilizers are used daily by farmers to increase seed yield. These fertilizers consist of nutrients used by plants and provide them with the required amount of nitrogen, potassium and phosphorus. These materials increase the storage capacity of the soil and increase its fertility.
Types of fertilizer
Fertilizers include six different types that will be mentioned in the following lines
Mineral fertilizer - types of fertilizer
Mineral fertilizers belong to the category of chemical fertilizers. These fertilizers include nutrients that are produced by chemical methods and are essential for plants.
Chemical fertilizers are divided into the following two categories:
Nitrogen fertilizers - types of fertilizers
These fertilizers contain nitrogen needed by the seeds, which helps them grow. Nitrogen is the main component of chlorophyll and regulates the process of photosynthesis.
In addition, nitrogen is one of the constituent parts of amino acids and helps to form these molecules.
These fertilizers accelerate the cultivation of agricultural products and increase their quality.
Phosphorus fertilizers - types of fertilizers
As its name suggests, the main component of phosphorus fertilizers is the element phosphorus.
The efficiency of these fertilizers varies according to the percentage of phosphorus in them, and it also depends on the fertility method, soil characteristics, and the elasticity of the seeds.
Phosphorus in the protoplasm of plant cells plays a significant role in their growth and reproduction. This type of fertilizer is very useful for spreading the roots of plants.
Organic fertilizer - types of fertilizer
Chemical fertilizers belong to the category of natural fertilizers that are obtained from plants and animals.
These products enrich the soil with the carbon compounds needed by the plant and help its growth.
These fertilizers increase the content of organic matter in the soil, promote the proliferation of microorganisms and change the physical and chemical properties of the soil.
These substances are considered as one of the most important brain substances for green plants.
Organic fertilizers can be extracted from the following products:
* Agricultural Waste
* Excrement of cattle and cattle
* Industrial waste
* Urban sludge and sewage
Benefits of fertilizers
The benefits of using fertilizers will be mentioned in the following lines:
They are easy to store, transport and use. To provide a specific nutrient for the plant, you can use fertilizer containing those substances They are soluble in water and can easily dissolve in soil; As a result, they are easily absorbed by plants Their effect on seeds is immediate and fast They increase the yield of seeds and provide enough food for a large population They are reliable and the result obtained by them is predictableThe importance of using fertilizer
It is very difficult to meet the ever-increasing needs of the population with such few resources.
Loss of soil fertility, pests and lack of nutrients have led to a decrease in the production of agricultural products; This has increased the human need to use fertilizers in agriculture. Fertilizer products are essential for plants in the following areas: Fertilizers increase the tolerance and resistance of plants against pests. This reduces their dependence on insecticides and herbicides; As a result, it produces healthier seeds. Therefore, diseases have been reduced and the aesthetic value of plants has increased. Fertilizers have increased the water holding capacity of plants and increased the depth of the roots Potassium in fertilizers increases the strength and strength of the vessels and stems of plants Phosphorus in fertilizers helps in faster root expansion and seed formation Nitrogen present in fertilizers accelerates the growth of plants; This event is determined by the greenness of the plants Because chemical fertilizers have unpleasant effects on soil fertility, biological fertilizers were invented and are used today. These products are products containing living or dormant cells, and even microorganisms. They add nutrients and microbes needed by the plant to the soil and help maintain its fertility. These products are compatible with the environment and destroy compounds that are pathogenic for plants. Acetobacter and rhizobium are the most widely used biological fertilizers.
