4R Plus combines the 4Rs of nutrient stewardship — the Right source of fertilizer, applied at the Right rate and Right time, and in the Right place — Plus in-field and edge-of-field conservation practices that can increase productivity, bolster soil health and improve water quality. Examples of these practices are cover crops, strip-till and no-till,  bioreactors and saturated buffers and others.
