John Saad

Managing Director, CHT Australia Pty Ltd

In the context of Irrigation and soil management John Saad comes from left field, he is a graduate Chemist who has spent his whole career in application chemistry, which began in the late 70s working for more than 10 years in the field of Industrial Speciality Chemicals, John then spent the next 17 years in the area of adhesives and coatings.

Over the course of his career, John started from Technical Sales and advanced through the businesses into various management roles, culminating in his appointment to CHT Australia as Managing Director 10 years ago, with the guiding objective to diversify towards modern sustainable chemistries for the overall Australian Market.

It is John’s holistic approach based on many years of experience in aqueous chemistry applications and his response to the challenge thrown at him for Sodic Soil remediation that has seen CHT Germany emerge as a new key player in soil chemistry around the world.

Abstract Outline: This presentation is based on recent field studies, elaborates the CHT concept of managing irrigation cycles through management of surface tension and charge balance of the soil, and is advocating the principle of water movement through the soil rather than focus on water retention.

Through the use of patented Siloxane chemistries, field studies show that it is possible to increase or reduce the infiltration rate of water and expel sodium from and through soil, much more rapidly than either Gypsum or Lime.

Whether your objective is higher soil friability, less stickiness, lower dampness on harvest or changes to water infiltration, it is time to think beyond Gypsum and Lime and start thinking surface tension and charge balance. Once we do that, a whole new dynamic of soil management opens up for us to optimize our chemical and irrigation programs to reduce our overall cost.

If you really need increased calcium, then the use of Lime or Gypsum becomes much more effective with a greater flow of water through the soil. The other benefit is that by increasing the flow of water through the soil, you are more likely to disperse and release retained nutrients much more efficiently.
