Like there's no doubt with Brazil co
Science, Sustainability and the Art of Farming
In today’s episode: agriscience versus nature. The ability to farm land productively and profitably requires that farmers bend nature to their will on some level. But that doesn’t mean that farmers and scientists can’t find ways to work with nature, minimize off-target effects and conserve biodiversity. A great model species to think about these concepts related to farming and nature is t
Revolutionary Plant Breeding: Breakthrough Unlocks Hybrid Wheat
In today's episode, the challenge and opportunity of hybrid wheat. We've discussed previously how much hybrid corn has increased corn yields over the past century. Wheat is an important crop around the world; but why haven't hybrids been commercialized in the same way? Today we take a look at how agriscience is changing the game for hybrid wheat. Corteva Agriscience is on the cusp of mak
Crucial Conversations About Biologicals in Agriculture
In today’s episode, we start to unpack the category of biologicals. Are biological products ready for prime time on the farm, or still struggling to prove their return on investment? Where are biologicals finding traction and what are the barriers and opportunities for this category going forward? To begin to peel back some of the layers of this nuanced topic, we’ll speak with Corteva res
Fueling Growth in Winter Canola
In this episode, what would a truly renewable biofuel look like? Well, the feedstock would have to come from a crop that is productive, profitable, and resilient to grow. And one that has a low carbon intensity score that’s going to displace minimal amounts of acres of other cash crops. Could winter canola be that crop? It’s sure looking that way, in the mid-south at least. Today we hear
Fungicide Timing Solution: Confident Application to Maximize ROI

Too Tall? A Look at Reduced Stature Corn
In today's episode: Does corn really need to be so tall? It's time to explore this concept of reduced stature corn, otherwise commonly referred to as short corn. When you picture a mature cornfield, I imagine you're probably thinking of tall green stalks, towering overhead, and there are some agronomic advantages and disadvantages to this.So some corn breeders are developing varieties th
Science Makes Active Ingredients More Active
In today’s episode we dive into a critical topic that is usually hidden in plain sight: formulation science.It’s easy to think of agricultural products as straightforward chemistries that get sprayed from a tank. An insecticide is an insecticide; a fungicide is a fungicide. The active ingredient is what is going to give us the outcome we want. But a product is not just made up of that act
Permanent Cover Crops Take Root
In today’s episode: what might it look like to create a better cover crop system? A group of researchers and farmers are seeking to answer this question.Cover crops can help reduce soil erosion, preserve soil biology, build organic matter, suppress weeds and improve water and nutrient retention. So why do fewer than 10% of US row crop acres incorporate cover crops? There is risk involved.
