Rose Dunn: Welcome back to Agweek TV. It's the time of year to think about crop nutrition, and joining us now is Curt Woolfolk, the senior agronomist of the Mosaic Company. What trends are we seeing in crop nutrition this spring?

Curt Woolfolk: So there are seventeen essential elements that crops need, and so it's very important to look beyond those macro nutrients like N, P and K, and really start looking at the eight micro nutrients, and how those play a part in proper crop nutrition. So when we look at those balances between the macro nutrient, secondary macro nutrient and then the micro nutrients, you know, it's important to understand that each crop has an uptake and a removal pattern and just kind of understand those, and what fertilizer we need to apply to our soil to meet the crop needs.  

Rose Dunn: So what is Micro Essentials and how is it different from other fertilizers?

Curt Woolfolk: Yeah, Micro Essentials is a premium phosphate product. It's a dry granular product. We have a sample here of the Micro Essentials S Z. That's the sulfur and the zinc. The main difference with a Micro Essentials type product is, you have a homogeneous granule, where the nitrogen, the phosphor, the sulfur and in this case the zinc, is all in one granule. That becomes very important when you compare that against a traditional blend. Often as growers we use a map, a monammonium phosphate, you know, eleven fifty two oh. We'll typically put in an ammonium sulfate or maybe even a zinc sulfate in that blend. As we go apply that product, if we're using an air seeder or an air drill, often we don't get really good uniform nutrient distribution. So by having all four nutrients in one granule, you get very good uniformity of nutrient application, and that gives a lot more access for different root systems of different crops to take up that nutrient. Especially when it comes to micro nutrients.

Rose Dunn: So what crops is this used on?

Curt Woolfolk: There's a multitude of crops that can be used. There's three formulations because we do tailor some of the formulations a little bit by geography. So Micro Essentials S 15 is very common for the Canadian provinces as we look at  more canola and flax type crops. A little bit higher on the sulfur. As we get more into Montana, the Dakotas, and Minnesota, we're often looking at more corn, soybean rotations, so we're looking at the Micro Essentials S Z product.

Rose Dunn: What key nutrients are needed to ensure the growth of a healthy soybean crop?

Curt Woolfolk: The growers that do apply fertilizer to beans often think about potassium first, you know, K is front and center for that soybean grower. The research at Mosaic that we've conducted recently has really shown a light on the fact that soybean responds well to sulfur, and even some of the micro nutrients like boron.

Rose Dunn:  Very important. Where can we learn more about Micro Essentials?

Curt Woolfolk: We have several great resources at the Mosaic company. We have Micro Essentials dot com. We also have a great resource, crop nutrition dot com. So if you ever have a desire or a need to learn more about what does sulfur do within a soybean plant, what does the potassium do for the corn crop? Go to crop nutrition dot com and find a wealth of resources available there.

Rose Dunn: Great information today, thank you for being with us today, Curt Woolfolk, the senior agronomist of the Mosaic Company.
