Tissue Testing and Interpretation for Florida Turfgrasses

Tissue analysis offers a precise estimate of a plant’s nutritional status at the time of sampling. Nutrient deficiencies can be detected with tissue analysis before visual symptoms appear. This three-page fact sheet describes the importance of tissue testing and how to interpret the results. Written by T.W. Shaddox and published by the Environmental Horticulture Department.

Soil and Plant Tissue Testing

Soil Sampling.  Soil testing is the best tool for monitoring soil fertility levels and providing baseline information for cost-effective fertilization programs. But a major limitation is that it typically accounts for the plant-available nutrient pool present in the surface soil layer. Because of the extensive root system in some plants, plant analysis is a complement to the soil test to better assess the overall nutrient status of a perennial forage system, while revealing imbalances among nutrients that may affect crop production. This 4-page fact sheet was written by Maria L. Silveira, and published by the UF Department of Soil and Water Science, June 2014.
