1. Cover Crops for Nitrogen Management in Irrigated Cropping SystemIn perennial fruit cropping systems, the inter-row offers on opportunity to grow a cover crop that then can be used to supply nitrogen (N) to the fruit crop. We conducted research in both Concord grape and Gala apple to evaluate the potential of cover crops to supply N to the crop. Based on continuous monitoring of plant available NO3-N by using PRSTM ion exchange resin probes, we found that in Concord grape, while both hairy vetch and yellow sweet clover did not release quite as much N as...

2. What You Need to Know About the National Fertilizer Recommendation Team Called FRSTThe Fertilizer Recommendation Support Tool (FRST) team is a national effort to improve coordination of soil test recommendations in the United States. There are over 125 partners involved in FRST with representation of all four regional soil testing committees including WERA-103. The team has developed a national tool for P and K soil test calibrations (identifying critical soil test values for response to fertilizer), and are working on developing P and K calibration, tools for S calibration,...
