What is the best fertilizer for corn?
There is no best, one-size-fits-all recommendation for fertilizing corn (Zea mays) that fits all soil conditions. Some soils contain more plant nutrients than others. The most accurate way to determine fertilizing needs for corn is to have your soil tested.
How much 10-10-10 fertilizer do I put on my corn?
For a larger plot of corn, till or plow 25 pounds of 10-10-10 fertilizer into the top 6 inches of 1,000 square feet. When your plants have developed four or five fully expanded leaves, apply 1/2 to 3/4 pounds of 10-10-10 fertilizer no closer than 2 inches from the base of your plants and rake it into the top 2 inches of soil
When to apply nitrogen-only fertilizer to corn?
You should apply one final application of the nitrogen-only fertilizer once the corn ears have started to produce silk. Doing so will provide enough energy to carry the corn through until harvest.
Should manure and fertilizer rates be based on crop history and manure use?
When fertilizer and manure rates are applied as suggested for agronomic response, nutrient losses into the environment are relatively small and optimum economic production can be achieved. As mentioned, for nitrogen, guidelines are based on crop history and manure use.
How to determine fertilizer needs for corn?
The most accurate way to determine fertilizing needs for corn is to have your soil tested. Lacking a soil test, there are some general recommendations that apply to nitrogen-loving corn. Water-soluble granular fertilizer is most often recommended.
How to get nitrogen out of corn?
When corn plants have eight to 10 leaves, add 1/2 pound of urea, 46-0-0 fertilizer, to each 100 square feet of soil. Scatter the fertilizer 6 inches from the sides of your plants and water it into the soil. Repeat this with 3/4 pound of urea when your plants develop silk. Another way to address the high nitrogen need of corn is to add 1 1/2 pounds of ammonium nitrate, 34-0-0, for each 100 feet of row when the plants are 8 to 12 inches tall. Sprinkle this at least 2 inches from the base of the plants and rake it 2 inches deep into the soil.
Do you fertilize in square feet?
If you fertilize in a square, hill or circle, then fertilizer recommendations in square feet are more useful than those for length of row. Always water the soil after you apply fertilizer.
Band Rates
The fertilizer used as a starter should contain a small amount of nitrogen; most, if not all, of the recommended phosphorus; and possibly some potassium. Thus, a good starter fertilizer might range from a ratio of 1-4-0, 1-3-1, 1-3-3, to 1-1-1, depending on the rate of fertilizer required.
Efficient Nitrogen Use
It is important to determine as accurately as possible the quantity of nitrogen necessary for optimum economical corn production and to apply only this quantity of nitrogen to prevent over-fertilization.
Nitrogen Status of the Corn Crop
One can determine whether the proper rate of nitrogen was used by examining the crop. This hindsight evaluation helps refine nitrogen management. Nitrogen sufficiency in one year does not necessarily imply that N rates should be decreased in the next year, and vice versa. Examine the lower leaves of the cornstalks.
Adapt-N – Incorporating Weather Information to Adjust Corn N Rates in Season
Appropriate nitrogen rates for corn vary greatly among locations and growing seasons. In some years corn is nitrogen deficient, while in others the same amount of fertilizer appears to be adequate. This happens because the appropriate N fertilizer rate is highly influenced by weather, soil, and management factors.
What is the best fertilizer for soil?
After working the compost into your soil, you should then apply an all-purpose fertilizer with an even distribution of the following elements: Nitrogen. Phosphorus. Potassium.
Why is my corn weak?

How many leaves does corn need?
