What is the difference between Milorganite and Pgf complete? Milorganite fertilizer provides the grass or plants with a better root system and makes the grass more strong from inside to survive in any unusual circumstances. On the contrary, Pgf complete fertilizer has a Humic DG particle that enhances the soil structure and works as a natural soil conditioner.
Moreover, when we have to say the name of the two most popular slow-release nutrients fertilizer, it has to be Pgf complete and Milorganite without any doubt. But, when you are thinking about buying one fertilizer between these two, things can become confusing for fertilizing your lawn area.
Let’s compare the Pgf complete vs Milorganite with a table to choose the better one.
PGF Complete Vs Milorganite: Figure out the Difference
| Key Point | Pgf Complete | Milorganite |
| Ingredients | Nitrogen, Phosphorous, and Potassium are (4-1-2) ratios, respectively. 3% iron. Humic DG. | Milorganite NPK composition (6-4-0): Nitrogen- 6.0 % (3% slow Nitrogen), Phosphorous- 4.0 %, 0% potassium. 85% Water-Insoluble (WIN) properties. |
| Best Application | Centipede, Zoysia, Bermuda, and St Augustine. | Fescue, Perennial ryegrass, Kentucky bluegrass. |
| Efficacy | Within 5 days to 6-14 days’ time limit. | Typically 1-2 weeks to 10 weeks. |
| Application Rate | 18 Ib bag for each 5000 square ft. | 32 Ibs for every 2500 square ft. |
| Price Difference | Price is higher than milorganite. | Less expensive than pgf complete. |
Ingredients
Nitrogen, Phosphorous, and Potassium are the essential ingredients of Pgf complete fertilizer. Therefore, when we measure it, we get Nitrogen, Phosphorous, and Potassium (4-1-2) ratios, respectively. In addition, 3% iron and some Humic DG are also included to help the nutrient processing.
Milorganite NPK composition is (6-4-0)ratio maintaining primary nutrients: Nitrogen 6.0 % (3% slow Nitrogen), Phosphorous- 4.0%, and less than 1% potassium.
Secondary nutrients are Iron- 2.5 %, Calcium 1.2% and about 85% Water-Insoluble (WIN) properties.
Best Application
Regarding the PGF complete fertilizer, Centipede, Zoysia, Bermuda, and St Augustine are all types of warm-season and cool-season grasses suitable for irrigation purposes.
On the other hand, Fescue, Perennial ryegrass, Kentucky bluegrass, or cool-season grasses are suitable for Milorganite used soil. The time limit is 4 times each year.
Efficacy
Usually, when PGF complete fertilizer is applied on lawn soil, it results within 5 days. The best impact time after irrigation is 6-14 days. The PGF complete helps increase the grass inches so fast that most golf professionals use it.
In this fact, Milorganite typically takes 1-2 weeks which is enough to show the green grass activity. But the best impact time is 10 weeks.
Application Rate
The application rate of the PGF complete is 18 Ib bagS for each 5000 square feet lawn. The application rate is about 50 % to 70% during the summer season.
The Milorganite uses 32 Ibs or pounds for each 2500 square feet lawn. You can mix 1 part seed with 4 parts Milorganite fertilizer for better results based on recommended packet application rate.

Moreover, when you start to apply the Milorganite fertilizer, the fertilization process has to be slow to get the deep root of these grasses. Neither, the root growth may stop, and the upper portion of the grass increases its size using the nutrients. It may create a small root size if you don’t follow this.
Price Difference
PGF stands for Professional Grade Fertilizer. This fertilizer has vast demand as all large-sized and professional golf lawns users apply it. So, the price is higher than Milorganite without any doubt.
But the Milorganite is less expensive than PGF complete.
How Fast Green The Lawn?
Heat-dried microbes are the primary nitrogen source of the Milorganite fertilizer. Its Water-Insoluble (WIN) properties help release Nitrogen in a slow process when the plant needs them. Milorganite goes through 20 parameter analysis processes every day before supply to the market. When soil temperatures are 55–85 F, the microbial activity helps the grass absorb the nutrients properly.
The Milorganite takes a minimum of 1-2 weeks and a maximum of 10 weeks to green the lawn area. On the other hand, when we look at Milorganite vs PGF complete the success rate is high for pgf complete within a less time limit. It only takes a minimum of 5 days to 14 days. That’s why professionals love to use them.

Frequently Asked Questions (FAQs)
Is Milorganite the best?
Milorganite consists of many heat-dried microbes. When plants need the nutrients, Milorganite fertilizer slowly releases them with the help of microbial activity. The making procedure of Milorganite is the ancient recycling effort to release nutrients. It fertilizes the grassroots and helps to adjust it firmly in the soil. So that’s the reason Milorganite is the best.
Why use Milorganite?
Milorganite is made of microbes, and with the application of heat, the microbes have to dry first. Microbes eat the nutrients from the water because these microbes are full of nutrients.
Another advantage is there is no need to pour water after fertilizer is mixed in the soil. But water added will increase the soil absorption capacity more than before.
What is equivalent to Milorganite?
Milorganite is the biosolid fertilizer that is organic. It is used in most gardens and lawns because of its popularity. But its price rate is getting higher day by day, and sometimes there remains a supply shortage.
So alternative fertilizers of fully organic categories are used instead of it. These alternatives also have slow-release nitrogen capacity. Following are some of those alternatives of Milorganite.

Concluding Part
When you go to the market to buy fertilizer, you may confuse about which fertilizer is better when choosing PGF complete vs Milorganite. Though these both are slow-release fertilizers, they have Nitrogen, Phosphorous, and Potassium at different ratios to feed the grass.
Milorganite is full of dried microbes necessary for grass root strength, and the PGF complete has the Humic DG particle to structure the soil properties. Between the two fertilizers, PGF complete has the potential to grow your lawn grass larger in a small limit of time.
