Things to consider before choosing the Fertilizer

Apply the fertilizer as per the requirement of the soil. You must test the soil before fertilizing it.

N-P-K Ratio

Fertilizer and turf fertilizers are listed by number, by weight, for three specific nutrients: Nitrogen (N) promotes pigmentation and accelerates growth, phosphorus (P) promotes plant and seed formation, and potassium (K) promotes plant growth. Although all three are necessary for the grass of St. Augustine, it is a well-developed, highly nitrogenous soil nutrient.

St Augustine grass usually contains more nitrogen than phosphorus and potassium. The typical composition of turf fertilizer, for example, has an NPK rating of 15-1-5. As you browse the grass compost, you will see how many NPK compounds it produces, but almost all of them are very high in nitrogen.

Formulation of Fertilizer

The fertilizers are available in three ways: liquid, granular, and soluble in water. 

Liquid 

It is more convenient for farmers and caregivers to use liquid manure to grow grass faster since it is absorbed and starts working quickly, encouraging new growth. Results can be seen 3 or 4 days after applying the liquid fertilizer to the grass of St. John’s. Augustine. As a liquid fertilizer passes through the lawn quickly and escapes, it may be necessary to apply it more frequently than granular varieties.

Granular

Granular fertilizer contains many of the same nutrients as liquid manure. Granular fertilizers are generally released more slowly, so grassroots have access to nutrients for longer. Granules will not provide instant growth like liquid manure, but they usually require less work. Granular manure is applied to the grass using a spreadsheet.

Soluble Water

You can use a hose-end dispenser attached to a garden hose to prepare the water-soluble fertilizer. Water flows into the dispenser, disperses and purifies the granules, and disperses the fertilizer with a hand-held spray. Like liquid manure, water-soluble manure can quickly turn green.

Chemical Fertilizer

The manufacturing of these fertilizers takes place in factories and chemical laboratories. Most of the synthetic fertilizers are the products of different industries. We need them in less quantity as they are concentrated. This fertilizer is cheaper compared to organic fertilizer available in the market. They contain essential nutrients and are rich in nitrogen, phosphorus, and potassium. 

Organic Fertilizer

Organic fertilizers are natural resources that contain a limited amount of essential nutrients. They can reduce the problems associated with synthetic fertilizers. They reduce the need to double the fertilizer applied to maintain soil fertility. They gradually release nutrients into the soil solution and maintain nutrient balance for St Augustine growth.

The fertilizers also serve as an active source of healthy microbes, which improve soil structure and plant growth. Organic fertilizers are full of trace elements, and they loosen the compost slightly. Hence, they are a safe alternative to chemical fertilizers.
