How to select fertilizer for grass

1.Elements Fertilizer
Grass needs enough amount of nutrients, water and sunshine to sustain life and grows healthily and green. The importance of fertilizer is the same as water, air, and temperature in the soil.

Most fertilizers all contain three different nutrients: Nitrogen, Phosphorus, and Potassium.

Nitrogen
Nitrogen plays a critical role in the process of photosynthesis, It promotes healthy leaf growth by encouraging the production of chlorophyll, which is a chemical vital to photosynthesis.

Not only does it help with that though, but it also can help plants fight off damaging pests. Plants that are deficient in nitrogen grow poorly and develop yellowing leaves.

Phosphate
Phosphorus is an essential macro-element, required for plant nutrition. And is involved in the metabolic processes responsible, such as photosynthesis, energy transfer and synthesis and breakdown of carbohydrates.

The presence of phosphorus in the soil help turf grows lush and thick because it promotes strong root growth. Plants with a phosphorous deficiency will experience stunted growth.

Potassium
Potassium helps regulate plant metabolism and affects water pressure inside and outside of plant cells to keep the lawn healthy and balanced.

For these reasons, potassium is critical to plant stress tolerance. This affects all aspects of lawn and garden well-being, from cold and drought tolerance to disease and pest resistance.

2.Bio-Fertilizer

Biological fertilizer is the new substance that contains living microorganisms applying on seeds, leaf or soil.

They are of paramount importance in cycling nutrients in the lawn soil. They act as a long-term fertilizer and health system for your lawn.

There are two main different types of soil microbes. Each of these microbe types has a different job to boost lawn health.

Bacteria
Bacteria are the final stage of breaking down nutrients and releasing them to the root zone for the plant. Proper bacteria can create a good soil environment and control root diseases for the lawn.

Such as Bacillus Subtilis, a species of bacteria with strong soil adaptability. It has a good effect on colonizing grassroots and inhibiting harmful pathogens.

Biodiversity in the soil is also essential for daily grass management, Beneficial fungus has a good effect on building healthy root systems, maximizing the use of fertilizer and improving soil conditions.

Fungi
The most popular fungal agent is Mycorrhizae and Trichoderma harzianum, which are already commercially used.

Mycorrhizae form a mutually beneficial relationship with grassroots, stimulating lawns to grow thick and lush.

mycorrhizae fungi
Trichoderma harzianum helps improves soil structure and inhibits fungal soil-borne pathogens, including Fusarium (wilts), Rhizoctonia (root rot), Sclerotinia (blight), Drechslera tritici-repentis (Leaf Spot).

3.Organic Fertilizer

Organic fertilizers contain organic material(mainly manure, compost, or other animal and plant products), which improve the soil’s structure.

Soil with organic matter is easier to allow more air to get to plant roots. Also, the addition of organic substances used in fertilizer increases the bacterial and fungal activity in the soil.

There are generally three different types of organic lawn fertilizer.

Plant-Based
The effect of plant-based fertilizers doesn’t last as long as other organic options but they’re generally the best way to condition the soil.

Because One of the major benefits is they can be very effective at helping dry soils hold onto water.

Animal-Based
These fertilizers include things like bone meal, blood meal, and manure. They add a lot of nitrogen to the soil and are great for the beginning of planting season or when you first seed your lawn.

Mineral-Based
An example of organic mineral-based fertilizer is calcium or Epsom salts which can add necessary nutrients to the soil while also adjusting the pH.
