Fertilizers come in different forms, both natural and artificial.


Fertilizers of recent makeup usually have three essential elements

  • Nitrogen
  • Potassium
  • phosphorus
  • dust from rocks for additional nutrients.

Fertilizers in a wide array of ways. Fertilizers can be in their dried form and liquid form. Keep in mind that there are other modes of application besides those mentioned above.

Do I Need to Apply Fertilizer?

As stated above, fertilizer is naturally occurring or artificial. Although farmers have cultivated their crops in time past without fertilizer, it does not repute that fertilizer is absent. Nature will have a hard time trying to replace minerals or nutrients left out of the soil the crops panted.

Occasionally, during plants’ harvesting, essential minerals and nutrients are also sucked out of the ground and the crops. The land would have lost most of its nutrients after the harvesting season and will need to add fertilizers that will improve the quality of the earth. Otherwise, the next farming season will experience a vast decrease in the yielding of crops. Not only do these fertilizers feed the soil and the plants, of course, after harvesting, but it is also going to end up on the tables of man or as food to other animals.

International Fertilizer Association

These fertilizers also carry nutrients that are beneficial to humans and animals alike. It is stated by the International Fertilizer Association, commonly known as the IFA, that a whooping eighty five percent(85%) of soil samples tested all around the world lack the element nitrogen, which is one of the nutrients that aid the healthy growth of plants and plants cannot take this nitrogen from the air.

Hence, their only source of nitrogen is the soil. They also have realized that seventy-three (73%) of these soil samples lack phosphorus while fifty-five (55%) lack potassium.

Potassium: It is found in soil but is way beyond the reach of the roots of the crops. This vital nutrient is almost a kilometer deep in the ground.

Phosphorus: It is also another naturally occurring element in soil but is in specific types of rocks. Crops cannot access these because the crops need to have water solubility. Hence the importance of phosphorus-based fertilizers as crops can extract from the soil.

Types of Fertilizers

Fertilizers come in different forms that best fit the soil they are for. There are four forms or types of fertilizers available for cultivation in agriculture. Any experienced farmer or gardener is well aware of the value that good fertilizers carry.

Approximates of the nutrient content are usually printed on the sacks because there is no natural way to know the number of nutrients it contains. Because this type of fertilizer is naturally occurring, like most natural things, it takes a while for its effect to show.

Hence is used mainly by farmers to develop rich and healthy soils over long periods. A huge advantage that organic fertilizer carries is that it is made easily in your home.

Unlike organic fertilizer, if you plan to speed things up In your farm or garden the inorganic fertilizer is your best fit. They are the best if your crops increase.

Nitrogen Fertilizers

The element or nutrient that takes responsibility for the growth of plants is nitrogen. The element nitrogen’s importance in fertilizers is good as it plays a significant role during the mid-stage of the lifespan of different crops.

Phosphate Fertilizers

The nutrient phosphorus is a requirement for plants all through their life span. The nutrient is responsible for the strengthing of the roots of crops along with their stems. The use of phosphorus-based fertilizers usually gives flowering, the production of seeds, and ultimately fruits a boost.

Potassium Fertilizers

The nutrient responsible for making your crops develop deeper, healthier, and more robust roots is known as potassium. Potassium is an essential nutrient because it enables your crops to thrive even when they lack other nutrients. Potassium is also crucial in the process of photosynthesis. Potassium-made fertilizers can also reduce the speed or completely kill any form of plague that may affect your farmland garden.
