Organic or Synthetic Fertilizers

Whether it is organic or synthetic, both types of fertilizers can provide nutrients to plants and grass. By knowing each’s advantages and disadvantages, you can choose which to prefer in making your grass tougher and greener.

Organic Fertilizers

When the environment is of concern, most people would prefer organic fertilizers.

Organic fertilizers contain natural ingredients, which typically consist of marine emulsions and processed manure. Because of this, most organic fertilizers exude a stinky smell. 

The other downside of organic fertilizer is that identifying the exact amount of nutrients it has is difficult. That is why using it requires more effort. Also, there are organic fertilizers that require digging into the soil and mixing before usage.

Because it is difficult to determine the exact amount of nutrients, a gardener may still need to look for more fertilizers to suffice what is lacking.

On the other hand, most gardeners prefer organic fertilizers when it comes to fruit trees, ornamental plants, etc. It is because it is safe for the environment, and it allows the plants to grow naturally. As a result, the fruits and vegetables will be more flavorful and safer from harmful chemicals.

Synthetic Fertilizers

Synthetic fertilizers contain a concentrated ratio of nutrients. Because synthetic fertilizers are artificially manipulated, they are easy to use. You are sure that what is on the label is not an estimated amount. Because of this, you can easily mix the right amount that your grass needs.

Aside from that, synthetic fertilizers are commonly cheaper than organic.

Despite the convenient benefits that synthetic fertilizers can provide, they still have disadvantages. One is that most chemical fertilizers contain unwanted elements that can deplete the soil quality. Many of them have chemicals, such as cadmium and arsenic, that are toxic to the plants and can creep its way to the fruits and vegetables. 

Factors to Consider When Buying the Best Fertilizer for Green Grass

If you want to buy the best fertilizer for your green grass, you need to consider the following factors.

Type of Grass

It is easy to ignore the type of grass that you have on your lawn. After all, it is just there to add some green to compliment your home sweet home. However, if you are serious about adding some green to the appearance of your home’s backyard and not ugly yellow, you need to consider the type of grass growing on your lawn.

The typical ones are zoysia, Bermuda, St. Augustine, and ryegrass. Knowing the type of grass on your lawn is the main consideration when you are making a purchase. Take note that not all fertilizers are suitable for all types of grass.

One example is the Scotts Turf Builder Bonus S Southern Weed and Feed. Some of its previous users complained about this fertilizer ruining their Bermuda grass. However, these users were not aware that this fertilizer is only usable for some types of grass, such as the zoysia and St. Augustine. 

Because of this, aside from just knowing the type of grass you have on your lawn, you should also read the label to determine if your fertilizer is suitable for it.


The macronutrients are commonly represented by the NPK or nitrogen, phosphorus or phosphate, potassium, or potash. You will find the ratio of these nutrients on the label in the form of number-number-number, such as 16-4-8. This ratio represents the percentage of NPK.

For this example, a fertilizer with a 16-4-8 ratio has 16 percent nitrogen, 4 percent phosphorus, and 8 percent potassium. These nutrients are the major ones that the plants need.

The recommended balanced ratio is 4-1-2. However, it does not mean that you opt for this. You need to place your grass’s needs as your utmost priority when choosing a fertilizer. 

Commonly, grasses are heavy nitrogen feeders. That is why you will see that nitrogen is always enormous in amount compared to phosphorus and potassium.

To determine the right ratio, you need to determine the nutrients that are lacking. To find it out, you need to perform a soil test. This test will help you figure out the nutrient that is lacking in the soil. 

With this information, you can find the fertilizer that can make up for the deficiency. 

Some manufacturers choose to omit the phosphorus out of the ratio because of environmental concerns. When phosphorus reaches the ocean, it can cause quick algae growth that might exceed what the world can handle. This growth will decrease the dissolved oxygen levels, the type of oxygen that marine animals breathe.

Aside from that, these algae can produce toxins that are harmful to humans and animals. 

Mode of Application

Commonly, fertilizers come in two forms regarding their usage. It can be in the form of spray or granules.

From the word itself, fertilizers in granule form have solid, pebble-like contents. Fertilizers in this form are easy to use because you only have to spread them. However, granular fertilizers usually need watering afterward to soften them up, so the soil can absorb their nutrients.

If you choose to buy fertilizer in granular form, make sure to use a spreader. Please do not use your hands because the fertilizers might spread unevenly, or they might even burn your hands.

Granular fertilizers have a slower release, which is beneficial because it allows thorough absorption of nutrients. It is also a better option for you if you do not have time for reapplication. It is because granular fertilizers tend to last for a longer time.

Granular fertilizers are beneficial if you are located in a rainy place. Moist soil can maximize the benefits of granular fertilizers.

On the other hand, spray fertilizers are commonly in concentrated liquid form. Unlike the granular fertilizers, you are in control. You can apply fertilizer evenly without missing a spot. 

Spray fertilizers are beneficial, especially if you reside in dry areas. Spray fertilizers fertilize and water your grass at the same time. 


There are tons of fertilizers that you can choose from on the market. Hopefully, this article has helped you narrow down your options and learn how to pick the right fertilizer appropriate for the grass on your turf.

Despite this recommendation, you still have the last say about the best fertilizer for your green grass. To determine the best, you should know the type of grass on your lawn, the NPK ratio, and the best application method for you.
