Don’t Forget Zinc when Applying Phosphorus to Your Farm

Phosphorus (P) fertilizer is often added to cropping systems to increase yield, but growers should not overlook the importance of micronutrients like Zinc (Zn). Understanding some of the nutrient interactions that affect nutrient availability can help with management decisions like fertilizer source.

Magnesium for Balanced Crop Nutrition

Magnesium (Mg) is one of three secondary macronutrients, along with calcium and sulfur, required for balanced crop nutrition. Often overlooked, Mg deficiencies can lead to reduced crop growth and yield.


Banding Phosphorus as a Bandage for low-pH soils?

In the mid-1970s, Dr. Robert Westerman banded 18-46-0 with wheat at planting in a low-pH soil near Haskell, Oklahoma. The impact was immediately evident. Soon after, Oklahoma State University published an extension brochure titled “Banding Phosphate in Wheat: A Temporary Alternative to Liming” (Figure 1). This method was a temporary solution for the significant amount of Oklahoma winter wheat that was either too far from a reliable lime source or under a short-term-lease contract.


Phosphorus Fertility for Winter Wheat

It’s important that producers not overreact to lower crop prices for wheat by cutting back this fall on phosphate fertilizer if it is needed. Wheat is a highly responsive crop to phosphate fertilizers. At low soil test levels, good profits can be made by using the right rate of phosphorus applied at the right time and in the right manner.


Mastering Early-Season Fertility

Whether you are growing wheat, canola or corn, you can set the stage for a healthy growing season and maximum yield with early-season treatments and starter fertilizer.

The Impact of High Yields on Deficient Soils

Record yields equal record removal of nutrients and should indicate a need for record soil nutrient replenishment.


Sulfate Sulfur vs. Elemental Sulfur Part II: Characteristics of S Oxidation

The oxidation of elemental sulfur (S⁰) to sulfate sulfur (SO₄) in soil is a biological process and is carried out by several kinds of microorganisms. The rate at which this conversion takes place is determined by three main factors:

1. the microbiological population of the soil;
2. the physical properties of the S⁰ source; and
3. the environmental conditions in the soil.


Identifying Boron Deficiency in All Crops

One of the micronutrients essential for crop health also happens to be one of the most deficient in agriculture: boron (B).


Bringing a Horticulturist’s Eye for Nutrients to Montana’s Golden Triangle

The ‘Golden Triangle’ in north-central Montana is called that for its bountiful wheat harvests. Chris Barge looks at the near-perfect moisture conditions this past fall and winter, sees the know-how of the growers in his area, and foresees an exceptional year for winter wheat in the Golden Triangle.

Adapting to a Rapidly Changing, Knowledge- and Technology-Driven Industry

The CPS location Lance Loveless works for, located just 4 miles south of Delphi, Indiana, and about 25 miles northeast of Purdue University in Lafayette, Indiana, is in an area ripe with productivity for many corn and soybean farmers. The area is also home to a diverse farming community, with farmers ranging from the 200-acre hobby farmer who works in town to the 9,000-acre farmer whose farm is his business, along with a number of large pork producers.
