I plan to use 50 lbs. ammonium sulfate, 50 lbs. potassium nitrate, 3 lbs. manganese sulfate, and iron and micros per acre. I will decrease rates depending on the weather. I am wanting to add citric acid to this mix. I will not be able to run the irrigation immediately after treating but I can leave instructions for customers to run irrigation the following morning. Would citric acid be possible in this scenario and if so what rate and water volume would I need? Treating mostly Centipede.
