I recently submitted a soil sample to a local company whom caters to mostly golf courses. The results were PH 6.6, Calcium base saturation 63.0%, Magnesium Base saturation 29.10, Potassium Base Saturation 5.90%. They recommended (20 #per K of Gypsum Magic), (5#per K of 0-0-50), (50# Per K of 1-20-0), (10# Per K of 18-46-0) Any alterrnatives or your input. I priced this program at $1450.00 that's 3.5 times the cost of materials. with their schedule it will take 12 mos to complete. the test cost 50.0 with recs. I'm learning more everyday.
