Do your crops contain the optimal nutrient levels necessary to produce top yields? Plant tissue testing with SGS is a great way to diagnose a nutrient deficiency or toxicity problem in your field.

Tissue testing is typically performed in-season when a problem has been detected in a field, but can also be used as a compliment to soil testing. By doing routine tissue sampling at the proper time throughout the growing season, you can verify that your fertility program is working, make adjustments for in-season fertilizer applications, and detect problems before they are visually evident. Tissue testing can also help diagnosis problems caused by factors unrelated to soil nutrient deficiencies, such as pesticide use or injury, varietal or hybrid differences, or soil compaction.

SGS tissue packages include: Nitrates; Basic Test (total N, P, and K); Standard Test (total N, P, K, S, and Zn); and Advanced Test (total N, P, K, S, Ca, Cu, Fe, Mg, Mn, Zn, Na, B). Sample corn tissues when the plant is less than 12” tall, by collecting all of the plant that is above ground. If the plant is taller than 12”, collect the first fully developed leaf from at least 12 plants.

Collect the entire above-ground portion of the plant when collecting soybean seedling tissue samples. Otherwise, collect the youngest mature trifoliate leaves from the top of at least 20 plants prior to or during flowering.  Send samples in paper bags and ship to the nearest SGS laboratory in Belleville, IL; Brookings, SD; or Toulon, IL.
