Analytical Services

Water and Hydroponic Nutrient Solution: place at least 10 fl. oz. in a clean bottle.  The analysis results will include pH. Electrical conductivity (EC), and level of all the plant essential elements.  Interpretation of the results will be given if the potential or current use is given.

Soilless Rooting Medium: take an aliquot of rooting medium (organic, perlite, rockwool) from top to bottom from several locations or rooting vessels and let the water drain from the taken samples. Do not air dry but place into a plastic bag and seal.  The sample will be assayed for its pH and level of essential plant nutrient elements, and an interpretation of the results made based on current or potential use.

Soil Testing: sample to a depth of 6 to 8 inches, taking a sufficient number of cores representing the area being tested. Place 2 cups of soil in a suitable container and mail to the address below.  Analysis results will include pH and level of the essential major elements and micronutrients. An interpretation of the assay results and lime and fertilizer recommendations will be given if the crop to be grown is specified.

Plant Analysis: collect fully mature leaves just below the growing terminal from at least 10 plants, or several leaflets from several plants to make a composite sample of at least 10 leaflets. For specific sampling instructions, request by email: Before shipping, allow the leaf tissue to air dry in the open air for 24 hours. Then place the leaf tissue in a clean paper envelop.  The plant tissue will be assayed for all the essential elements and an interpretation of the results given. Include plant species, sampling date and visual appearance of the plants sampled. When dealing with a suspected nutrient element insufficiency, collect leaf tissue from both normal and insufficient-appearing plants in order to make a comparison interpretation.

Analytical Fee:  $25.00 per sample by check or money order.

Dr. J. Benton Jones has written extensively on the topics of soil fertility and plant nutrition over his professional career. After obtaining a B.S. degree in Agricultural Science from the University of Illinois, he served on active duty in the U.S. Navy for two years. After discharge from active duty, he entered graduate school, obtaining M.S. and Ph.D. degrees from the Pennsylvania State University in agronomy. For 10 years, Dr. Jones held the position as research professor at the Ohio Agricultural Research and Development Center (OARDC) in Wooster. During this time, his research activities focused on the relationship between soil fertility and plant nutrition. In 1967, he established the Ohio Plant Analysis Laboratory. Joining the University of Georgia faculty in 1968, Dr. Jones designed and had built the Soil and Plant Analysis Service Laboratory building for the Georgia Cooperative Extension Service, serving as its Director for 4 years. During the period from 1972 and his retirement in 1989, Dr. Jones held various research and administrative positions at the University of Georgia. Following retirement, he and a colleague established Micro-Macro Laboratory in Athens, Georgia, a laboratory providing analytical services for the assay of soils and plant tissues as well as water, fertilizers, and other similar agricultural substances. Dr. Jones was the first President of the Soil and Plant Analysis Council and then served as its Secretary-Treasurer for a number of years. He established two international scientific journals, "Communications in Soil Science and Plant Analysis" and the "Journal of Plant Nutrition", serving as their Executive Editors during the early years of publication. Dr. Jones is considered an authority on applied plant physiology and the use of analytical methods for assessing the nutrient element status of rooting media and plants as a means for ensuring plant nutrient element sufficiency in both soil and soilless crop production settings.
