Plant and Soil Test Calibration for Irrigated Crops in Southern Idaho
Phosphorus based manuring can limit N applied for triticale and increase purchased N fertilizers. Plant analysis may help determine N shortages. Plant analysis of reproductive tissue may be more appropriate for alfalfa seed production than using vegetative tissue. The purpose of these studies are to identify triticale N concentrations necessary for maximum boot stage forage and P uptake and reproductive alfalfa tissue B for predicting the need for foliar B.
