SHP and TFI publish Nutrient Management ProfilesBy SHP Staff on Monday, 20 April, 2020
In partnership with The Fertilizer Institute (TFI), SHP published two profiles discussing SHP farmers who are implementing soil health management practices and the changes in their nutrient management strategy.
Properly managed nutrients and soil health can provide economic and environmental benefits; however, cropping systems are complex. Nutrient management decisions must align with soil health management decisions for optimal results. 4R Nutrient Stewardship provides a framework to achieve cropping system goals, such as increased production, increased farmer profitability, enhanced environmental protection, and improved sustainability.
The two profiles discuss mobile macronutrients and immobile macronutrients.
Potassium helps strengthen the plant’s ability to resist disease and plays an important role in increasing crop yields and overall quality, including strengthening the plant’s root system. Phosphorus is linked to a plant's ability to use and store energy, being necessary for overall growth and normal development. Phosphorus and potassium nutrients are typically lost through surface water, washing away the fertilizer source or erosion.
This profile highlights two U.S. farmers who incorporate 4R practices into their soil health management system to keep the phosphorus and potassium they apply in the soil.
Profile: Mobile Macronutrients - Nitrogen
Nitrogen fertilizer is commonly applied to row crops, such as corn, to improve yield and quality of the harvested crop. However, nitrogen that is not used by a crop or leaves the field can be released into the air(ammonia and nitrous oxide), surface, and groundwater (nitrate).
This profile highlights two U.S. farmers who incorporate 4R practices into their soil health management system to optimize nitrogen use.
