Maximizing Fertilizer Investments Without Sacrificing Yields

Every fall, when it comes time to plan for the upcoming growing season, you look for ways to better manage nutrients and maximize your costly fertilizer investments – all without sacrificing yields. Factors such as fertilizer prices, weather conditions and the bottom-line numbers all play a role in your thinking, all while dealers look for helpful ways to assist in this important decision.

That’s where AVAIL® Phosphorus Fertilizer Enhancer, from SFP, can play a role. Researchers estimate as much as 75 to 95 percent of applied phosphorus[1] (P) fertilizer becomes fixed in the soil in the initial year of application (making it unavailable for plant use), but you still need to produce prosperous crops. To do this, nutrients must be applied at optimal rates – and at optimal times – to avoid deficiency and to maintain manageable input costs. In order to ensure adequate nutrient availability and uptake, growers worldwide use AVAIL with their P fertilizer applications.

Consider AVAIL this fall

In choosing AVAIL as part of a fall P application program, you will have an advantage this spring when time is often scarce and valuable. Additionally, AVAIL is proven to work throughout the winter to protect fall-applied P and ensure it’s available when the plant needs it in the spring.

“In field trials with AVAIL, we’ve found AVAIL-treated acres can increase the availability of applied P fertilizer regardless of when it is applied,” says Barney Gordon, Ph.D., agronomic consultant and emeritus professor in Kansas State University’s department of agronomy.

“Research also shows that AVAIL-treated phosphorus out-yielded non-treated whether applied in fall or spring.”

Smart decisions in fall = prosperous spring

Now, you have the knowledge and product – with AVAIL – to apply your P in the fall. This gives you the security of knowing your AVAIL-treated P will be available come spring.

Advanced crop technologies, like fertilizer-efficiency products, also allow you to adapt to changing growing conditions while achieving yield goals.


AVAIL is a water-soluble additive for dry or liquid P fertilizer and acts as a shield, protecting the fertilizer from elements like aluminum, iron, calcium and magnesium that would normally tie up P and render as much as 95 percent unavailable to the plant.
