I have been using APSA-80 for over 20 years. Since we are on strict water rationing, the fact that I can still achieve 200+ bushels of corn with 2–3 acre-inches less water is critical. It varies year to year, but my average return on investment is at least $60 per acre.
Conducted test plots and after positive results recommended trial plots on selected farms. One example is a pecan farm with compacted soil. Irrigation used to take nearly 80 hours, but after using APSA-80 the irrigation time reduced to 20 hours. Water savings was about 40% and yields increased by 20%.
In a four year, two site study, APSA-80 resulted in significantly increased root depth and crop yield. Corn root depth measured 90%. Root volume increased from 25 to 56% and corn yield increased from 13 to 17%.
