Feeding the Grain: How to Maximize Source-to-Sink During Fill 🌾 In a good growing year, the question becomes: how do we push yields even higher? When the crop is healthy, water is adequate, and the plant is cruising, it’s the perfect time to turn our attention to the “source-to-sink” relationship—the internal system plants use to transport nutrients to their grain. Understanding Source-to-Sink Think of the grain—the kernels or the beans—as the babies. These “babies” cry out for nutrients, and the plant responds by directing sugars and nutrients their way. The louder the baby cries, the more it gets. Agronomically, this process is called the source-to-sink relationship—with the “source” being the leaves producing sugars and the “sink” being the grain demanding them. To push yield, we want to make the babies cry louder and open up the delivery highways. Boron and Molybdenum: Making Grain Cry Louder Micronutrients play a huge role in this. Two of the most effective are boron and molybdenum. Boron increases auxin levels, the hormone responsible for nutrient movement. Normally, auxin is regulated by enzymes like IAA oxidase, which keep things in check. But when boron is applied, it suppresses that enzyme—letting auxin levels spike and turning up the volume on the “crying baby” signal. Molybdenum, on the other hand, impacts a different hormone called abscisic acid (ABA)—the one responsible for shutting things down. When molybdenum is in the mix, it slows the plant’s progression into dormancy, helping it focus on finishing and filling grain instead of growing new leaves. Nitrogen: Opening the Highways Nitrogen also plays a key role. It increases turgor pressure, which helps move nutrients faster through the plant. Adding foliar nitrogen—such as melted urea—paired with boron and molybdenum can be a powerful way to improve uptake and nutrient flow. Even in late applications, nitrogen helps widen the lanes for nutrient delivery during critical fill stages. Timing Matters For corn, one of the best times to make these applications is around tassel, when nutrient demand is high and tip-back can be prevented. Flying on foliar nitrogen during this period, especially when paired with micronutrients, supports strong grain fill and minimizes kernel abortion. For soybeans, timing is more flexible. An R2 (full flower) application of boron and molybdenum works well in most regions. But in places like Brazil, a late-season finishing spray—even up to R5 or beyond—can still show yield benefits. As long as there’s green tissue, the plant can still respond. That said, spraying after the tissue has browned is too late—by then, nutrient flow has stopped. In Summary: How to Push Yield in a Good Year Make the grain scream: Apply boron to boost auxin and drive sugars into the grain. Slow down shutdown: Molybdenum increases ABA, signaling the plant to finish what it started instead of growing new leaves. Widen the pipeline: Nitrogen increases pressure and flow, helping everything move faster. Time it right: Tassel in corn, R2–R5 in soybeans. Focusing on this internal nutrient highway can help ensure every kernel and pod reaches its full potential. Whether you’re farming corn, soybeans, or wheat, managing the source-to-sink system is one of the smartest ways to turn a good year into a great one. 📈 Learn more by watching our full-length podcast episodes or exploring our other agronomic content on YouTube and social.
