Hydroponics has had a long history of development and use with varying commercial success.  Today, hydroponics has a bright future.  Unfortunately, few are engaged in method development, designing growing systems that can be used by the commercial grower as well as the home gardener.  Hydroponics future lies in urban agricultural use, growing fruits and vegetables for local consumption.  With the use of enclosed chambers, growth rooms and greenhouses, year round production is possible. The commonly used hydroponic growing methods are wasteful in their use of water and reagents needed to make a nutrient solution, and require a reliable source of electrical power, skilled use of nutrient solutions, and environmentally acceptable procedures for the disposal of leachates from the rooting medium and spent nutrient solution which are considered “hazardous waste.”

This website describes a hydroponic growing system that is energy efficient and totally utilizes the water and nutrient elements applied to the crop.

• all of the water and nutrient elements pass through the plant
• no runoff of water and nutrient solution
• no accumulation of elements as solutes or precipitates in the rooting medium
• no need to water leach the rooting medium
• no discarding of spent nutrient solution
• no electrical power required
• one nutrient solution formulation sufficient from all crops and stages of plant growth

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.
