Diagnosing Nutritional Deficiencies

The correct diagnosis of nutritional deficiencies is important in maintaining optimum plant growth.  The recognition of these symptoms allows growers to ěfine tuneî their nutritional regime as well as minimize stress conditions.  However, the symptoms expressed are often dependent on the species of plant growth, stage of growth or other controlling factors.  Therefore, growers should become familiar with nutritional deficiencies on a crop-by-crop basis.

Record keeping and photographs are excellent tools for assisting in the diagnosis of nutrient deficiencies.  Photographs allow growers to compare symptoms to previous situations in a step-by-step approach to problem solving.  Accurate records help in establishing trends as well as responses to corrective treatments.

Because plant symptoms can be very subjective it is important to approach diagnosis carefully.  The following is a general guideline to follow in recognizing the response to nutrient deficiencies:


Summary

The diagnosis of nutrient deficiencies can be a key to optimizing plant growth.  However, this technique is very subjective and requires careful observation.  Plants respond to nutrient deficient conditions in several different ways.  Growers must become familiar with these on a crop-by-crop basis.  Photographs and record keeping can be very useful tools in the diagnosis of nutrient deficiencies.
