Abstract or Summary
  • Fertilizer studies at the Oregon State University Vegetable Research Farm were conducted for two years to evaluate the effect of different nutrient sources on yield and selected quality components. Sources of nutrients included sewage sludge, fresh and dried poultry manure, a soybean residue from oil extraction, and several mineral fertilizers. Different rates and time of application were studied to determine optimum response. Most rates were based upon equivalent amounts of total nitrogen. Vegetables grown were bell peppers, cucumbers, radishes, snapbeans, sweet corn, table beets, and tomatoes. The experimental design included a randomized block design of sixteen treatments and four replications on a Chehalis silty clay loam soil. Soil analysis indicated a reasonably fertile soil. The organic materials studied, with the exception of the soybean residue, indicated that they produced yields comparable to equivalent rates of mineral fertilizers. The highest yields were obtained with some of the organic materials on many crops. The soybean residue exhibited phytotoxicities depressing plant grown and yield on both direct seeded and transplanted crops. The cause is presently unknown. Responses to the fertilizer treatments varied from crop to crop. Generally, the main yield response of each crop to nutrient elements was as follows: Bell peppers, N; cucumbers, N, P and K; radishes, P and K; snapbeans, P; sweet corn, N; table beets, N, P and K; and tomatoes, N. When high yields were obtained, little difference was found in selected quality components between nutrient sources, as shown in the bell pepper and tomato flavor evaluation and the tomato fruit nutritional analysis. The chemical analysis of the sewage sludge indicated a low trace element content. Results of the mineral analysis of the radish roots and heavy metal analysis of the sweet corn grain fertilized with sewage sludge compared to an unfertilized control, indicated no trace element and heavy metal accumulation. No strong trends of increased mineral levels from sewage sludge were found from soil and plant tissue analysis.
