Plant Tissue Analysis.

In the past, tissue analysis was interpreted in a number of ways. One method relies on the critical levels of the minerals in the plant tissue. The critical level is defined as the point below which a nutrient deficiency will result in a 10% reduction in yield provided that all the other nutrients and growth factors are not limiting growth. Critical levels for each nutrient have been established by extensive Balchem research in greenhouses using plants grown in nutrient solutions.

Another way of interpreting plant tissue analysis is to look at optimal ranges. The Diagnosis and Recommendation Integrated System (DRIS) was developed to incorporate the importance of nutrient balance into plant analysis. This system relies very heavily upon yield and plant analysis data gathered from the field over an extended period of time. Ultimately, the system is designed to indicate the appropriate ranges for all the essential nutrients that will maximize quality and yield.

In the case of the macronutrients (N, P, K & S) the foliar application should only be considered a supplement to these elements being supplied by the soil. In most cases soil applications of these elements will be required in addition to the recommended foliar sprays. When trying to determine plant nutritional needs, plant tissue analysis can provide some very important information. Being able to accurately interpret the results of a tissue test is critical to success. Balchem’s unique T.E.A.M. reporting system provides you with all of the necessary information to accurately diagnose and address specific nutritional problems.
