My soil test results (performed by UMass) for my lawn indicate acidic soil (5.8), and a recommendation to apply 50 lb of lime per 1000 sq ft now, another 50 in the spring. The same test also indicates high magnesium and calcium levels (250 ppm Mg, 1850 ppm Ca - with normal ranges considered 50-120 and 1000-1500, respectively). Under these circumstances, am I better off applying agricultural or dolomitic lime? Or does it not matter?
Dolomitic limestone contains calcium carbonate and magnesium carbonate.
It would be best to apply agricultural limestone, a finely granulated calcitic limestone. It is easier to apply in the pelletized form. Follow label directions.
