What Is The Purpose Of Fertilizers For Plants?

Growing healthy crops requires healthy soil. It provides nutrients to the plants. If we don’t use fertilizers, the soil has difficulty replenishing itself with nutrients.

The removal of important nutrients from the soil is a consequence of harvesting crops, because the nutrients follow the crop to our dinner plates. The yield of crops will deteriorate over time if the soil is not replenished with nutrients through fertilization.

The analysis and fertilization of crops are crucial to creating a food supply chain that provides humans with nutritional food:

  • The soil is nourished by the nutrients
  • It is the soil that feeds the plants
  • People and animals eat plants

Mineral fertilizers based on nitrogen, phosphorus, and potassium are the most common.

According to the International Cultivar fertilizante Association (IFA), 85% of soils worldwide lack nitrogen. Seventy-three percent of the soils lack phosphorus, while five percent lack potassium.

What Is The Purpose Of Fertilizer?

There are often few alternatives without fertilizers for plants to avoid nutrient deficiencies.

The soil is the only place in which plants can acquire nitrogen since plants cannot absorb it directly from the air. Fertilizers are needed to boost soil nutrition if it is low on nitrogen.

Potassium occurs in high concentrations below the surface of the soil (often around one kilometer below) and is not accessible to the roots of plants. Through potassium mining, this naturally occurring nutrient is brought close to the surface of the soil and within reach of plant roots.

While phosphorus can be found in certain rocks, it must be water soluble in order for plants to access it. Plants absorb the phosphorus they need from the soil through phosphorus fertilizers. This ensures rapid growth, high productivity, and a high quality of life.

Which Is Better, Mineral Fertilizers Or Organic Fertilizers?

Looking after the environment: choosing the right fertiliser for your garden · NARC Environment Magazine

There are 17 nutrients necessary for plants to thrive in nature. It depends on what crop you grow, as well as the nutrient deficits in your specific soil, what kind of fertilizer you need. The crops you grow extract different amounts of nutrients from the soil.

The NPK compound fertilizers provided by most farmers provide several nutrients simultaneously.

The use of organic fertilizers such as animal waste and compost has been going on for centuries. These fertilizers provide nutrients and organic matter, which enhances the structure of soils.

Mineral fertilizers have been required to meet the increasing food needs of a growing global population since the 20th century. Organic fertilizers contain different amounts of nutrients, which are much less concentrated than those found in mineral fertilizers.

The use of mineral fertilizers reduces the amount and number of vehicles required to transport the fertilizer products.

According to the United Nations(2), the population of the world is expected to reach 9.8 billion by 2050. Increasing crop yields is essential if we are going to be able to feed everyone.

It is impossible to achieve this growth without carefully planned fertilization.

How Do Fertilizers Benefit Plants?

The exact amounts of nutrients in the mineral fertilizer make planning the farming process easier as well. There is now an increasing availability of fertilizers containing major, secondary, and micronutrients.

It is common to find mineral fertilizers in convenient solid granular form, so they are easy to carry and apply by the farmer. Nutritionally deficient and inadequately fertilized soil will often result in plants that are smaller and grow at a slower rate than soil from healthy soil.

What Is The Importance Of Nutrients To Humans?

The nutrients from fertilized soil are transferred to our bodies when we eat wheat, apples, potatoes, and other plants. We get the same results if we eat animals that have eaten plants that have the same nutrients as the plants.

The calcium in milk, for instance, will prevent our bones from becoming brittle and weak.

Nevertheless, milk will be less calcium-rich if the cows are not grazing on fields where enough of this mineral is present in the soil.
