Ok did as advised here and got my soil tested through UMass. The question I have is it is stating I should apply 93 lb of calcitic limestone/1000 sq ft in split application. Do not apply more than 50 lb/1000 sq ft at one time. And also 2 lb/1000 sq ft of P205. It says my soil PH is 5.9 and best I can tell everything else listed is within range. Yes some are low and high within the range, but everything is within range. The only other thing that stands out is that Potassium is 187 PPM which is very high. The recommended dose of calcitic limestone seems like quite a bit when I am not seeing anything totally out of whack. What am I missing? Since I have about 1000 sq feet of lawn where the heck do I buy a 50 lb bag of calcitic limestone? And how would you recommend applying 50 pounds to a 1000 sq feet? And last, but not least if I am to apply 2 lbs of P205 how would you recommend doing that? Best I can tell P205 is not sold straight, but is usually mixed in with other stuff. Am I right here? Can I buy it straight? Thanks in advance for any comments/suggestions!
