Top 5 Liquid Lawn Fertilizers

Ingredients Needed For A Good Liquid Lawn Fertilizer?

Liquid fertilizer is to be used on your lawn or garden to provide the desired boost of vital nutrients to your plants or grass. The chemicals in these mixtures are unique, but they all include the same basic components. Studying these chemicals might help you pick out the best fertilizer for your plants or lawn throughout the year, depending on what is happening with the soil around them.

Four Key Ingredients Needed:


Liquid fertilizers, on the other hand, usually include nitrogen. N promotes dark green grass growth, thick foliage, and stimulated top development in grasses and plants. Green lawns may be made with nitrogen, but too much nitrogen can suffocate flower and vegetable growth. It is better to apply a balanced fertilizer in the amount advised on the container, rather than applying excessive nitrogen. If you are going to fertilize for the first time, have your soil tested by a professional to discover how much nitrogen is in it and how much should be added. Fertilizers that contain nitrogen are made from a variety of chemical compounds, with animal dung, ammonium, urea, and nitrate being some examples.


Most liquid fertilizers include potassium, which is important for root health and development. Potassium, also known as K, promotes healthy roots and root growth. Muriate of potash or potassium chloride is two common forms of potassium that are supplied in fertilizers. Because potassium chloride is readily soluble in water, it can be absorbed by plants more rapidly when used as a liquid fertilizer. As with nitrogen levels, you can use a kit or have your soil tested by a professional to assess current potassium levels and avoid excessive applications that might harm grass and other plants.


The third primary component in most liquid fertilizers is phosphorus. Phosphorus is commonly known as P. It aids in plant photosynthesis and flower development. Phosphorus aids fruit production by moving energy throughout the plant’s structure in plants that produce fruit. Phosphorus is an important element for plant growth. Plants will not produce fruits and seeds germinate readily if there is a lack of phosphorus. When too much phosphorous is applied to the lawn or garden, plants may develop a zinc deficiency, resulting in stunted development.


Micronutrients are elements required by plants, but which may not be included in all liquid fertilizers. Calcium, zinc, boron, sulfur, magnesium, iron, and copper are examples of common micronutrients. Read the label on a liquid fertilizer to see if it contains all or part of these components. All fertilizers include a guaranteed analysis that shows the proportion of each component. Choose the appropriate balance of micronutrients for your soil after conducting routine testing.


Liquid fertilizers are made from a wide variety of chemical compounds, but most include nitrogen. Potassium promotes healthy roots and root development. Phosphorus is important for plant photosynthesis and flower development. There are a variety of micronutrients required by plants that may or may not be included in liquid fertilizer mixtures. Always complete a soil test before applying liquid fertilizers to your lawn or garden to ensure proper application and avoid over-fertilization.

I have been very impressed with this product. I have used dry fertilizers for years and always hated the process of spreading the fertilizer and missing areas on the lawn. The liquid is easy to apply and in the two applications I did this year, I never noticed any missed areas. I also think my lawn looks better than when I used the dry fertilizers. The only watch-out I have found is not to apply too much. I had an area of the lawn that I accidentally covered twice that developed lawn rust

Wow, this stuff works! No joke, I sprayed this stuff in my back yard where I have my 6 dogs do their business and had mostly yellow grass and roots. I went thru with a spike to aerate the really bad areas and then applied the spray to the whole yard. My yard exploded, I mean exploded with green. I the help of a little bit of rain, but the man did it made a huge difference. I may use another bottle of this in the still semi-dead areas.

This has greatly improved the soil structure of a compacted area of our lawn and solved some standing water issues from heavy clay. It has allowed the grass to thrive in those spots. In other areas, it has allowed the grass to grow well through some moss and eventually out-compete it. And in more areas, the turf is now filling in and starting to out-compete the weeds as I continue to mow it above 3″. We have been applying almost every two weeks as our soil was really in need of some help to grow grass well. Soon I noticed changes after the 2nd application and shortly after the 3rd, the results were pretty dramatic. I am just ready to apply a 4th time and let the lawn ride out the rest of the summer. I’ll re-evaluate in the fall and early next spring. I’m impressed.
