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.

Hydroponic Advancements

Over the last several decades, there has been little change in how plants are being grown hydroponically. Currently, there are 5 hydroponic methods in common use, flood and drain, standing aerated, nutrient film technique (NFT), drip irrigation and aeroponics . The last major advancements in the hydroponic technique occurred when...

Nitrate Accummulation in Plants

It is well known that plants being grown under low light conditions can accumulate nitrate (NO3), the amount depending on the growing conditions and availability of NO3-N in the rooting medium. Those growing plants hydroponically maybe able to reduce this accumulation by increasing the concentration of molybdenum (Mo) in the...

Measurement Terms for Elements in Nutrient Solution

The concentration of elements, both essential and non-essential, in a nutrient solution formulation are normally expressed in parts per million, best known by its acronym, ppm. In metric units, ppm is equivalent to milligrams per liter, its acronym being mg/L. A frequently used measurement for evaluating the overall elemental content...

Ammonium-nitrogen: Caution, It Can Adversely Affect Plants

There are two ionic forms of nitrogen that can be root adsorbed, the anion nitrate and the cation ammonium. Ammonium is more quickly simulated metabolically, while the nitrate anion must be reduced before metabolic simulation occurs, a reduction process that requires energy. Therefore, some have suggested that the ammonium form...

Is Your Hydroponic Growing System Efficient?

How efficient is your hydroponic growing system in terms of water, nutrient element agents, and electrical power use? A question every hydroponic grower needs to ask himself. How often and how many gallons of nutrient solution are discarded on a scheduled basis? How many pounds of reagents are included in...
