When soil pH is below 6.0, it can reduce your yield by as much as 30%. Calcium Products’ 98G pelletized limestone is the most effective and consistent product to correct and maintain soil pH. Soil pH has traditionally been addressed about every five years with aglime. Rather than create a pH rollercoaster in the field with infrequent aglime applications, 98G can be used as part of a pH maintenance program with annual or biannual applications. 98G is a more reactive liming material than aglime keeping soil pH at a level to maximize yield potential – typically 6.0 – year in and year out.
