pH Management in Irrigation Water
by Jim Gregory
CEUs applied for: APLD, IA, NALP, QWEL

Most salts in irrigation water are managed and not controlled. However, it is feasible to control both high bicarbonated and high ph with acids. High pH and bicarbonates will affect water quality and often limit plant health, color and productivity. The presentation will focus on why adjusting irrigation water pH is important, with emphasis on maintaining pH at 6.5 to 7.0, on a continuous basis.

TLE seminars are "more advanced than typical conference seminars."
