Good management practices are essential if optimum fertilizer responses are to be realized in the production of Brussels sprouts. These practices include use of recommended varieties, selection of adapted soils, weed control, disease and insect control, good seedbed preparation, proper seeding methods, and timely harvest. Because of the influence of soil type, climatic conditions, and other cultural practices, crop responses from fertilizer may not always be accurately predicted. Soil test results, field experience, and knowledge of specific crop requirements help determine the nutrients needed and the rate of application. The fertilizer application for Brussels sprouts should insure adequate levels of all nutrients.
Optimum fertilization is intended to produce top quality and yields in keeping with maximum returns.
The suggested fertilizer applications are based on 36-inch row spacing. With decreased row spacings, increased fertilizer rates are suggested. Recommended soil sampling procedures should be followed in order to estimate fertilizer needs. The Oregon State University Extension Service agent in your county can provide you with soil sampling instructions, soil sample bags, and information sheets. Transplanting Solutions Dilute solutions of complete fertilizers high in phosphorus promote quick recovery and early growth of transplants.
