PLANT TISSUE TESTING
From traditional row crops to fruits and vegetables, VAS can help you understand your plant’s nutrient status throughout the growing season or identify potential problems.
Laboratory plant tissue testing provides a snapshot of a plant’s nutrient status at the time of sample collection and can be used to fine-tune your fertilizer program throughout the growing season.
Gain a deeper understanding of the relationship between plants and your fertility program with a tissue test or testing program.
Track Nutrient Status
Track historical plant tissue results on a field or crop throughout the year
Fine-Tune Fertility Programs
Use tissue testing in conjunction with soil testing for a complete snapshot of nutrient status
Intervene to diagnose and treat distressed plants

Complete Petiole Analysis – Results include: Total Nitrogen, Phosphorus, Phosphate-Phosphorus, Potassium, Zinc, Calcium, Magnesium, Sulfur, Manganese, Boron, Iron, Aluminum and Sodium
Stalk Nitrate Testing – This end-of-season stalk test was developed to evaluate how well nitrogen fertilizer was utilized by the corn plant and allows the producer to distinguish between over-fertilization and fertilizing to maximize profits.
Cover Crop Biomass Analysis – Cover crops have the ability to take up nutrients, hold them and recycle them back into the soil for use by your next crop. Our Biomass Analysis provides a measurement of N and other key nutrients taken up by the cover crop and indicates how readily those nutrients will become available in the soil for the next crop. A measure of the C:N ratio is used to estimate this rate of decomposition.
If the cover crops are used for forage, gain a better understanding of the nutrients you’ll need to replenish for your next crop with this test.
Utilize VAS’ Cover Crop Biomass Analysis prior to terminating your cover crop (springtime or before planting your next crop). For sampling instructions and more information, contact your local VAS Laboratories’ location.
