The 4Rs of Nutrient Stewardship
The 4Rs of Nutrient Stewardship—Right Source, Right Rate, Right Time, and Right Place—are guiding principles to efficiently and safely use fertilizers. "Right Source" means choosing the appropriate fertilizer for the crop’s needs. "Right Rate" involves applying the correct amount to prevent waste and pollution. "Right Time" ensures nutrients are available when plants need them most, enhancing growth. "Right Place" involves applying fertilizers where plants can easily access them, minimizing runoff. Together, these principles help farmers maximize crop yields while protecting the environment and maintaining soil health.
