Use emerging tools and technologies to maintain responsible and sustainable agriculture. Make cropping decisions that result in higher nutrient use efficiency and increase farm profitability. Maintain and grow the farming operation to preserve the history, heritage and promise of the future for the next generation.

The key to successful 4R Nutrient Stewardship is including a nutrient management plan that is rooted in all 4R’s. This is because the 4R’s are based on scientific principles and the best available local evidence.

The 4 R's approach attacks a waste stream in a logical and methodical method by taking steps to sequentially Reduce, Reuse, Recycle and Recover a waste stream into incremental fractions.
