Fertilizers can be defined as substances that promote the growth of plants. These substances contain recognizable plant nutrients in their content. A commercial fertilizer also known as a chemical fertilizer or non-organic fertilizer usually contains primary nutrients which include Potassium abbreviated as (K), Nitrogen abbreviated as (N), and Phosphorous abbreviated as (P). This is marked on the bag as 10-10-10 as the national standard for the fertilizer. This means that it contains 10 percent of Potassium, 10 percent of Nitrogen and 10 percent of Phosphorous. This kind of fertilizer is described as a complete fertilizer. There is also the granular fertilizer which contains the same nutrients but balanced and packaged in the 12-12-12 formula.
There is also the 16-16-16 formula fertilizer, which is known as the Lawn Starter Fertilizer, which is good when you are starting a lawn, vegetables, trees, flowers, evergreens and shrubs. In addition to these ones, there are also the 14-14-14 and 15-15-15 formula fertilizers. They all contain the same basic primary nutrients, but in a higher ratio.
Apart from the chemical fertilizer, there is the natural fertilizer which contains organic substances such as yard compost and manure. There is also the incomplete fertilizer which doesn’t include one or more of the primary nutrients. There are many other kinds of fertilizers which include the straight and blended varieties. Straight fertilizers have only one nutrient in their composition while blended ones are mixed straight fertilizers.
Uses of the components of the fertilizers:
The chemical components in the fertilizers ultimately determine a lot. These chemicals are abbreviated as NPK meaning Nitrogen, Phosphate and Potassium. Nitrogen is necessary for the growth of the leaves. It is usually used a lot where lots of leaves are desired or where there are large plants. Legume plants such as peas require less nitrogen because they absorb naturally from the atmosphere. However, plants that constitute of narrow leaves like grains need a lot of nitrogen.
Phosphate is used for the health of the plant. Plants ideally use this chemical during the cellular process. A large percentage of it is found in clay soil, but very little of it can be found in sandy soil. Potassium or potash is used for healthy blooming and bearing of fruits. Therefore, it’s also used for the cellular processes.
Testing of the Soil
Different kinds of soil contain varying amounts of nutrients. The kind of soil in your kind may need a specific combination of the chemical fertilizers. Contact your local agricultural officers who will take a soil sample from the garden and analyze it. Additionally, they will be able to tell you which nutrient is needed most in the soil according to the plants that you are growing.
Know the Amount of Fertilizer You Need
Applying too much fertilizer is harmful to you and your crops. The amount of fertilizer you require is determined by the area that you are planning to farm. In addition to this, the kind of chemicals which are naturally contained in your garden and the type of plant you are growing should also determine the amount
