The University of Nebraska-Lincoln is excited to offer the first 4Rs Nutrient Stewardship Field Day from 8:30 a.m. to 3 p.m. July 15 at the Eastern Nebraska Research and Extension Center near Ithaca.
The 4Rs is a nutrient management and water stewardship approach that emphasizes fertilizer use with the right source, right rate, right time and right placement of fertilizers.
This science-based approach focuses on the best nutrient management practices and sustainable crop production, with increasing crop yield and farmer’s profit while protecting the environment.
Key advantages of following 4Rs nutrient management stewardship include:
- an efficient and effective soil fertility program for optimizing the crop nutrient requirements
- reducing the cost of fertilizer inputs while ensuring crop nutrient needs
- increasing synchrony of soil nutrient availability and crop growth and development
- reducing the potential for nutrient loss to surface water, groundwater and air
- enabling efficient use of water with the combined interaction of nutrient availability, crop growth and water use
- improving soil organic matter and soil health benefits with more crop biomass production
- increasing nutrient use efficiency by minimizing nutrient losses
Speakers from UNL, Nebraska’s natural resources districts and USDA’s National Resources Conservation Service will be presenting topics related to 4Rs strategies to improve crop yield and profits while protecting the environment. The event counts as 4.5 continuing education units on nutrient management.
The field day is free, but registration is required. More information is at agronomy.unl.edu.
Coordinating the event is Javed Iqbal, Nebraska Extension specialist and assistant professor of agronomy. He can be reached at [email protected] or 402-472-1432.
