Sure.
4R outlines the right source of nutrients, the right rate at which they need to be applied for the crops, the right timing so that plant uptake is optimal, and then the right placement—so, making sure that, where possible, it's banded under a subsoil versus broadcast. All of these practices—combined with technologies such as enhanced efficiency fertilizers, nitrification inhibitors and other products, and digital technologies such as precision agriculture—can help optimize nutrient use, reduce potential loss to the environment, whether through water or the atmosphere, and optimize the use of water and nutrients in the farmers' fields to create a more productive and profitable crop that's more sustainable from an environmental standpoint.
