A deep dive into the 4Rs starts where the original Nitrogen Smart ends with a detailed discussion on N rate, the contributions from soil and the stress from climate factors.
The 4Rs promote a nutrient management approach that balances crop productivity with environmental preservation:
Livestock manures have been used as a crop fertilizer source for thousands of years. It continues to be a valuable source of crop nutrients, even with the advent of synthetic fertilizers. Because its nutrient content and availability can vary widely, it's important to develop a management plan that will optimize crop productivity while protecting water quality.

This is a recording of the RIM-Riparian and Flo
2023 Webinar Replay - Session 3 covers seed mix design, the seed calculator, calculating PLS and bulk seed as well as MN seed tag law.
2023 Webinar replay - Session 4 covers the topics of cover crop seeding and termination methods as well as economics of cover crops.
2023 Webinar Replay - Session 2 covers the practice standard, Implementation Requirements worksheet, Agronomy Technical Note 33 and Cover Crop Identification.
2023 Webinar Replay - Session 1 discusses cover crop strategies, resource concerns that can be treated with cover crops, benefits of cover crops and how cover crops fit into MN cropping systems.
The National Organic Standards require certified organic producers to implement tillage and cultivation practices that “maintain or improve the physical, chemical, and biological condition of soil and minimize soil erosion.” While continuous no-till may be impractical for organic production of annual vegetable or field crops, innovative farmers and researchers have developed many tools and strategies to reduce tillage intensity and to minimize the adverse soil impacts of field operations in organic systems.
Extension educator Brad Carlson discusses split-applying nitrogen for corn and offers 3 tips for sidedress applications.
In this Tech Talk Jeff Duchene, NRCS State Grazing Specialist, provides an overview of the Livestock Forage Balance Sheet available in Section IV of the eFOTG under the CPS 528 Prescribed Grazing Conservation Practice Standard. Jeff discusses how to develop the livestock and forage inventory portions of the forage balance worksheet. Jeff also reviews the equations used to develop the livestock/forage balance and how to use those calculations in the field.
