I have a customer that over fertilized their lawn in june and their lawn started dieing off in a couple of days. Thinking about overseeding using a areo-vator or might just redoe completely. The problem I am having concerns the soil test. Soil testcalls for 118lbs lime per 1000sqft and the phosphorous levels are high off the top of the scale. Nitrogen 4 lbs and potash at 2 lbs per 1000sqft. I plan on putting 50 lbs lime per 1000 when I seed but aint sure what to do about the phosphorus. Area is about 10,000 sqft. Would tilling soil help with the high phos levels. If so I will do a complete redo but, if not I will try the areo-vator and overseed. Any suggestions are apprecated.
