A liquid fertilizer is a great nutrition mixture which provides the primary and secondary micro-nutrients, such as potassium and calcium, and even other micro-nutrients such as zinc and iron altogether, ideal for plants and crops. Hence liquid fertilizers are widely used by farmers to grow their crops and there are various ways of applying them. Here are some different methods on how to use a liquid fertilizer.

Step 1- Choose a Fertilizer

Liquid fertilizers are often criticized since there is a wrong idea that they wash out of the soil after some time. However, this is not totally true and it depends on whether you choose a natural or a chemical fertilizer. A natural liquid fertilizer is not water soluble and will eventually stay in the soil to feed the crops. Furthermore, a natural organic fertilizer is the best liquid fertilizer you can use since it provides the proper nutrients while it does not harm the environment.

Step 2 – Spraying a Fertilizer

One of the most common ways of using a liquid fertilizer is by spraying it on the plants' leaves. This process is generally referred as foliar fertilization and it can be done by using different sprayers such as a hose end or a larger tow-behind sprayer. Moreover, it is recommended not to apply this type of fertilization on a windy day but in humid weather conditions to make it easier for the plants to absorb the nutrients.

Step 3 - Banding Application

Another way to fertilize your crops is by using the band application system. This system is generally used when seeding and it involves running the fertilizer directly to the seed by means of a small “band”. Thus, this method quickens the growth of the plant but at the same time, if careful attention is not taken, it can damage the plant if the band is too close to the roots.

Step 4 - Fertigation System

For this method you should use a liquid soluble fertilizer since it is going to be mixed with water. As the name implies, this method involves fertilizing the crops while you are irrigating and it is commonly used in greenhouses. Hence, an irrigation controller will control the amount of fertilizer that is mixed with water. In addition this method does not require any machinery and ensures no time loss. Furthermore, the fertigation system guarantees no fertilizer loss since it is injected in the soil and it is always there when the plants need it.

So generally speaking, a liquid fertilizer is ideal for feeding plants which are already grown. Moreover, they are much more efficient than any other dry fertilizers which take longer to dissolve in the soil. Thus, whatever method you choose to use, a good fertilization is always guaranteed. However remember to avoid over-fertilization since it can kill the plants rather than make them healthier.
