See the 4R Practices in Action.
The 4R Principles are the foundation — but the real power comes when they’re applied through proven practices. Explore practical strategies that help farmers increase efficiency, improve soil health, and protect water quality.
Every farm is different, but the 4Rs can be applied anywhere through practices that balance profit, planet, and people.
From precision technologies to soil health systems, these practices show how the 4Rs work in the field.

Split Nitrogen Applications
The Right Time and Right Rate for nitrogen applications depends on many factors, including soil type and texture. For many areas in the Mid-Atlantic with relatively course-textured soils, it is good practice to apply a small amount of nitrogen at the beginning of the growing season, followed by one or more fertilizer applications later on. This allows most of the nitrogen to be applied nearer in time to when the crop will take it up, and reduce the risk of loss in a heavy rain event.
