In acidic clay, you want calcium nitrate as your N source and potassium nitrate for the K. No, it will not defloculate the soil provided you pay attention to the calcium levels. Because I often need to use calcium nitrate to correct magnesium excesses, sodium excesses, and acidic soil, potassium sulfate is no good for me. It forms concrete if mixed with calcium nitrate. I can also tell you that a good rule is no more than 1 lb of N per 10 gallons of solution. Especially in dry, non irrigated lawns. That rule is broken with me because I am spraying on lawns that were watered that morning and I am going to short cycle the system after application.
