18 years of High Q community data clearly shows one Known Known as you improve uniformity of a crop, you improve yield and reduce risk! That is a winning combination at any commodity price. Sleep better at night knowing you are getting the best possible return on your plant food dollar with Willard Nutriblend fertilizer.


Dry Vs Liquid Fertilizer

A key difference between Dry and Liquid fertilizer is the inherent uniformity of the product and uniformity of distribution. With liquid, you get a completely homogeneous product where literally every drop is the same. With a dry blend you get several different raw ingredients with different particle sizes and densities mixed together. The chart below illustrates how different some of these typical raw materials can be:

Product Density
Urea 46 lbs/ft3
Potassium Chloride 62 lbs/ft3
Ammonium Sulfate 50 lbs/ft3
DAP 57 lbs/ft3

As you can easily see, these different densities can cause tremendous stratification during transport as well as big differences in spread distance and pattern when hitting a spinner blade moving at a constant rate of speed. These differences result in LESS uniformity in any given field.

Dollars and Cents

Using High Q data on Wheat as an example you can begin to quantify the advantage of liquid fertilizer. For every % point increase in uniformity, on average, yields increase 1.3 bushels. Using liquid fertilizer feeds your crop consistently and evenly and maximizes the uniformity potential of any given field.

Willard Small Grain Topdress Recommendations

Include High Quality Boron with your first N/S application.

top-grain-1Replicated research by Ron Mulford, University of Maryland showed a 3.9 bu/acre yield increase by adding ½ lb/acre of elemental boron to your 1st topdress application. This is supported by 22,467 acres of High Q wheat data showing a 5.95 bu/acre average increase.

Use plant available sulfate sulfur from Willard Agri-Service in each application

top-grain-2Not all sulfur sources are plant available when soil conditions are cool. All Willard small grain N/S solutions are blended using pure 100% ammonium sulfate that drives higher attainable yields.

Replicated University of Maryland research shows an 18 bu/acre advantage to Willard sulfate sulfur over just 30% nitrogen alone or blends made with less available sulfur forms.

Balancing sidedress nitrogen with potassium, sulfur and boron critical to maximizing corn profitability

Research from the University of Illinois on the uptake and remobilization of nutrients by high-yielding corn hybrids is shaking up conventional wisdom on how corn uses key nutrients. Among the most surprising revelations arising from the study is the volume and use pattern of sulfur, according to crop physiologist Dr. Fred Below.

Since the last deep studies into the uptake and partitioning of mineral nutrients by corn in the 1980s, average yields have risen by more than 50 bushels per acre. The devastation once wreaked by corn rootworms has been held in check on millions of acres by bacillus thuringiensis (Bt) traits, Below notes. Those changes in the crop made it important to understand changes in how it grows, he says.

Among the findings of the Illinois study:

  • Half of the crop’s sulfur was taken up before flowering, with the other half drawn from the soil after flowering and utilized directly for grain fill
  • Unlike nitrogen, sulfur cannot be held in reserve in leaf tissue and remobilized to fill kernels sulfur is relatively immobile in the plant. That means roots need access to readily available sulfur late in the growing season
  • Sulfur has a high harvest index, which is defined as a nutrient that is vital for grain production and that ends up being exported with the harvest.

Willard Agri-Service uses ammonium sulfate which provides sulfur in the sulfate form. This fertilizer is immediately available to plants.

Dr. Below warns that decreases in the atmospheric deposition of sulfur as a result of the Clean Air Act, along with unprecedented levels of nutrient removal by high-yielding crops, threaten to leave many soils sulfur deficient.

Potassium: In addition to sulfur, potassium is crucial. Applying additional K with nitrogen during side dressing and fertigation will help support the ratio of uptake needed for maximum yield. See Dr. Flannery’s research below.
