How much fertilizer do you need for corn?
NPK ratio (amount of Nitrogen, Phosphorus, Potassium) is the identifier of good fertilizer. It also suggests the number of helpful elements for targeted applications.
Corns require plenty amount of nitrogen for successful growth. They absorb 65% nitrogen when the flowering begins, 10% nitrogen is accumulated in the seeding stage when trees get V5 (5 leaves). When corn grows from V6 (6 leaves) to V18 (18 leaves) at the rapid growth stage, 8 pounds of nitrogen in a one-acre area per 24 hours are absorbed.
After all, we have found that you may need to use one pound of nitrogen per bushel of grain produces in one acre area. Therefore, phosphorus helps in making the roots strong and growing them properly. On the other hand, potassium works on overall growth, from root development to corn production.

How do you apply fertilizer to corn?
First, you need to test the soil. Then, you can follow these methods to apply fertilizers to corn:
- Before Seeding:
First, spread 2 or 2.5 inches of compost over the field. Then, lightly sprinkle or mix nitrogen-based organic fertilizers. Use a spade to mix the compost and fertilizer well. As a result, the mixture will be 4-6 inches deep. Now, you can plant the corn seeds.
- Sprouts Care:
Try to apply liquid or granule fertilizer of 10-10-10 or close to it when the average height of corn sprouts will be 4-5 inches. The NPK ratio can be reduced or increased upon soil test. Adding some organic mulch at 2-3 inches thickness can be better with fertilizers. Re-apply the fertilizer when plants grow at 10 inches height. This is the best time for applying more nitrogen to the soil. The last time to use fertilizers when you see silk coming from the corns.
Can you over-fertilize corn?
We always think that using excessive materials may bring faster and brighter results. But in the case of corn cultivation this is not true. Fertilizers are good for growing plants stronger. But over usages of fertilizers can adverse effects. As an example, sweet corn grows well if you apply nitrogen and phosphorus well. But if the quantity of nitrogen is higher, then it may weaken the stems. Also, it may heat the field soon, which can let the plants burnt.
Is starter fertilizer advantageous for corn?
Antonio Mallarino, a soil fertility agronomist from Iowa State University Extension, says, colder soil and slow root growth condition is suitable for expecting early growth by applying starter fertilizer. But the grain yield may not be equal to early development. Again, some other experts suggest using fertilizers mainly when corns are at rapid growth or V6 stage. So, it is not always advantageous as our expectation to apply starter fertilizer.
Buying Guide – Choosing the Best Corn Fertilizer
When you are planning to put on fertilizers, you may get hundreds of ideas and names about corn fertilizer. But we are adding simple thoughts besides listing the best fertilizers for corn. You may get benefits if you follow these buying instructions:
Types of Fertilizers
Fertilizers are available in different forms. You can purchase concentrated, spikes, pellets, spray, etc., type fertilizers. But concentrated, pellets or granular types of fertilizers are primarily preferable for heavy-duty crop production. You can use them by mixing them into the soil. However, some of them are also applicable with sprayers.
Have a Soil Test
You may have already thought of skipping this point. But most experts suggest doing a soil test before planting seeds of corns. Testing the soil may indicate what type or quantity of fertilizers you would require.
Quantity of Fertilizers
High-quality products come with or mention the processes of applying them. You can read the application instructions written on the packages of fertilizers. Also, we suggest you follow a trial-and-error method for hands-on experience. Then, you can multiply or reduce the quantity according to growth development.
Nitrogen is a common ingredient of most fertilizers. It helps to produce the natural color of plants. Phosphorus and potassium work for overall growth. NPK ratio helps to know which one is greater in amount and suitable for a particular purpose. You can learn about the ratio written on the package’s body. However, we suggest you follow the NPK ratio to avoid unnecessary incidents.
Select the Organic Product
Organic fertilizers are always suitable for crop production. These fertilizers don’t have any harmful chemicals that may block the flow of feeding the right nutrients. Also, they can harm the soil microorganisms, which help to release nutrients slowly and consistently. You should prefer organic fertilizers to maintain the yields and taste of corn.
