 So we are a world leader in humic substances, humic acids, and those become kind of the foundation for all of our crop nutrients. So we have a technology which we call microcarbon technology. So it's carbon rich, but it provides an incredibly effective and efficient carrier for any type of crop nutrient out there. So as a result of that, we're seeing our nutrient products, whether it's super nitro and any of them, are delivered within the plant within one hour.
