Brief Project Summary:

Soil test calibration is a continuous process required to maintain up to date recommendations of fertilizers for different crops. Average crop yields are increasing yearly basis due to use of best management practices and the development of new varieties. NC State University is maintaining three long-term trials to check if phosphorus and potassium fertilizer recommendations based on soil testing are still adequate. The three long-term trials testing rates of phosphorus and potassium fertilizers are located at Tidewater Research Station (TRS), Peanut Belt Research Station (PBRS), and Piedmont Research Station (PRS). In one location, also poultry litter and levels of pH has been studied....

Information And Results
Project Deliverables

We will use the results of these trials to change, if needed, the rate of fertilizers recommended for North Carolina crops. We will present the results during the winter meetings and during the training of extension agents and crop consultants. We will promote field days to show the results of these trials and it also will be outreached by writing factsheets and videos to the soil fertility extension portal at NCSU (https://soilfertility.ces.ncsu.edu/).

Final Project Results

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
