To grow nutritious, healthy crops, farmers need to make sure they have healthy soil.Without fertilizer, it is difficult for nature to replenish the nutrients in the soil.
When crops are harvested, important nutrients are removed from the soil because they grow with the crop and end up on the table.If the soil is not fertilized with nutrients, crop yields will decline over time.
Analyzing and fertilizing crops can become a chain to provide nutritious food for human beings:
●The supply of nutrients to the soil
●The soil provides nutrients for plants
●Plants feed animals and people
The three most common mineral fertilizers are nitrogen, phosphorus and potassium.
The international fertilizer association (IFA) estimates that 85 percent of the world's soil is deficient in nitrogen, 73 percent in phosphorus, and 55 percent in potassium.
What is the use of chemical fertilizer?
Often, these plants lack nutrients almost without the help of fertilizers.
Studies have shown that many plants are almost always nutritionally deficient without the addition of additional nutrients from fertilizers to the soil.
Take nitrogen: because plants can't take nitrogen directly from the air, soil is the only way they can get it.If the soil is short of nitrogen, fertilizer is needed to improve nutrient levels.
Potassium sources are concentrated in large quantities below the surface of the soil (usually about a kilometer), far beyond the reach of plant roots.Potassium mining brings this naturally occurring nutrient to the surface of the soil and to the control of plant roots.
Phosphorus is found in some rocks, but plants need to be water-soluble to get it.Proper use of phosphate fertilizer can help plants absorb phosphorus through the soil, ensuring high yield and rapid growth.
What is the difference between mineral fertilizer and organic fertilizer?
There are 17 kinds of nutrients necessary for the growth of plants in nature.What fertilizer you need depends on what crops you grow and the lack of nutrients in each particular soil.Different crops absorb different amounts of nutrients from the soil.
Many farmers use a combination of nitrogen, phosphorus, and potassium to provide a combination of nutrients at the same time.
Organic fertilizers, such as animal manure and compost, have been used for centuries and are a valuable source of nutrients and organic matter that can improve soil structure.
But since the 20th century, mineral fertilizers have been required to meet the growing food needs of a growing world population.The nutrient content of organic fertilizers varies and is much lower than that of mineral fertilizers.
Mineral fertilizers reduce the amount of fertilizer products and vehicles needed to transport them.
The United Nations estimates that the global population will reach 9.8 billion by 2050.It is necessary to increase the output of crops if we meet enough food for everyone.
This growth is unlikely without well-planned fertilization.
What are the advantages of fertilizers?
Knowing the nutrient content of mineral fertilizers makes it easier to plan agricultural processes and farmers now have wider access to fertilizers containing major, minor and micronutrients.
Mineral fertilizers are mostly in the form of convenient solid particles and are suitable for transportation and use by farmers.Plants that grow in nutritionally deficient and unfertilized soils are usually smaller and grow more slowly than those that grow in healthy soils.
Why is nutrition important to humans?
When we eat wheat, apples, potatoes or other plants, nutrients from rich soil are transferred to our bodies.If we eat animals that eat plants that have the same nutrients, the same thing happens.
Fertilizers make healthy soil: the calcium in the soil is absorbed by the cows as they graze, and then transferred to us as we drink their milk.
For example, milk is rich in calcium, which can prevent our bones from being weak.
But if cows did not graze on land with enough nutrients in the soil, milk would not have that much calcium.
Therefore, planting food in a nutritionally balanced soil is the key to preventing malnutrition.It can also prevent diseases related to the scarcity of people around the world.
In Finland, for example, the government has required selenium to be added to all multi-nutrient fertilizers since 1984.In this way, they managed to fight heart disease with great success among the population.
