Show Vegetable crops need fertilizer experiments reveal j by Alvin R. Hamsun Acting Horticulture Fertilization experiments over a period Of years at Utah State University have indicated generally high requirements for nitrogen and phosphorous by vegetable crops grown in Nitrogen fertilizer should be applied each year to vegetable crops in most Phosphorous requirements depend upon past history of fields where vegetable crops are and gardners should samples of soil for test through County Extension Agents to determine the need for On row such as sweet corn or snap fertilizer can best be applied in bands at planting time provided equipment is available for proper Severe fertilizer injury will result if the fertilizer is placed closer than 2 inches to the side of the Best results are obtained if the fertilizer is placed approximately 3 inches to the side and 3 inches deeper than the Under no circumstance should the fertilizer be mixed with the seed or applied directly above or below the seed For transplanted such as cauliflower or the most economical placement of fertilizer is in bands 3 inches to the side of the plants and 6 inches deep For vegetable crops grown in rows of close such as lettuce or the fertilizer may be broadcast partly before plowing in the spring or drilled into the soil after the land is ready for planting Specific recommendations for the best fertilizer practice on each field and on each vegetable crop is often best determined through careful observation of crop response A careful record of fertilization practices should be kept on each field to determine fertilizer needs in future years In a number of carefully conducted fertilizer experiments on vegetable crops it has been observed that fertilizer response of vegetable crops is directly Influenced by the quality of irrigation water Although the air is largely it is not available to plants in this |
