Don’t Make Your Crops Stretch—Use a Starter Fertilizer to Promote Early-Season Growth
When you plant this spring, there’s a strong possibility that the seeds in your fields won’t have quick and easy access to everything they need to get off to a strong, healthy start.
While some nutrients like nitrogen and sulfur can move freely through your soil, many other essential nutrients—phosphorus and potassium, for example, and micronutrients such as zinc—are immobile and need to be placed as close as possible to the root zone for the plant to take full advantage of available benefits.
Starter fertilizers can help your crop get off to a strong start
You want your crop to put all of its available energy toward achieving maximum yield potential—not stretching for those vital early-season nutrients. This is where a starter fertilizer can play a significant role in the health of your crop.
By placing a starter fertilizer near your seed, you can set your crop up for a more uniform stand, better emergence in cool, wet soils and aided early growth.
Research has shown that starter fertilizers can be especially beneficial in no-till or high residue systems, coarse-textured soils and soils that test low for phosphorus.

How to determine the right starter fertilizer and placement
One of the most significant steps to selecting the right starter fertilizer for your crops is to determine its salt index—the sum of the nitrogen, potassium and sulfur in your fertilizer source. A 10-34-0 fertilizer, for example, would have a lower salt index than a UAN fertilizer.
Once you’ve determined a product’s salt index, you’ll want to consider your soil type to help determine the proper amount of fertilizer to place close to your seeds without damaging them or inhibiting their growth.
And no matter what type of soils on which you utilize starter fertilizers, placement in proximity to the seed is key. Those aforementioned immobile nutrients need to be placed close to the root zone, but too much nitrogen or sulfur can have a negative impact on overall germination.
