Pre-sidedress Soil Nitrate Test for Cauliflower (1996)
Introduction
Although we have established that cauliflower is more efficient that sweet corn or snapbeans in taking up fertilizer N, the large amounts of N applied to this crop (up to 300 pounds/acre) make it a candidate for improvements in N use efficiency. As with sweet corn, a predictive test of the need for late-season N applications could enable growers to cut back on wasteful and environmentally sensitive overapplication of N fertilizer.
