This book provides a comprehensive guide for vegetable growers and workers on how to conduct soil, plant, and water tests to assess soil health and water quality for irrigation purposes, as well as determine the appropriate nutrient balance for crops. As short-duration and highly photosynthetic efficient plants, vegetables require a high rate of nutrient supply compared to other field crops. Therefore, special attention must be given to the critical ranges and stages of soil and plant tests to ensure balanced fertilization. This manual provides a valuable resource for vegetable growers and workers to improve their understanding of soil, plant, and water analysis and nutrient management. The book includes information on the development of testing methods, calibration, and interpretation of results, making it a practical and useful tool for the vegetable growing community.
