Plant tissue analysis is a laboratory determination of the total elemental content of certain plant parts. It is used for a variety of purposes including monitoring the nutrient status of crops and troubleshooting problem areas. It also serves as the basis for nutrient recommendations for perennial fruit crops. Click below to access the request form. There are two versions available: one for the general public and another specifically for researchers.
lant tissue analysis provides diagnosis of nutrient deficiency or imbalance for major and micro-nutrient elements. It serves as a supplemental tool to soil tests. It can determine the effectiveness of your fertilization practices and help you correct nutritional problems during early growth season. Commonly tested nutrients include nitrogen, phosphorus, potassium, magnesium, zinc, copper, and boron.
What part of the plant should I send for analyses?
The plant part differs depending on plant species and state of development. In non-trees, the youngest, most fully developed leaves are used (but only during active plant growth seasons), while trees are often the most fully developed leaves in the mid-third of the canopy. Contact the laboratory for specifics for your species.
What should I put my plant sample in prior to shipment?
We recommend plant samples be placed in clean paper bags. Avoid putting fresh tissues in plastic bags, as degradation of the sample will likely occur in the mail.
Can you provide fertilizer recommendations based on my plant analyses?
No. All fertilizer recommendations are based on soil samples, not plant tissues.
Do you test for pesticides?
We do not test for pesticides in any samples.
