Bulk Dolomitic Agricultural Lime
Also known as: Dolomite Lime, Dolomitic Limestone, Ag Lime, Dolomite
Bulk Dolomitic Agricultural Lime is dolomite rock quarried and ground down to a fine material that you work into the soil to raise pH on acidic ground. It supplies both calcium and magnesium, which is what sets it apart from ordinary calcitic lime. Hudson Valley soils tend to run acidic, so this is the material you reach for when a soil test says you need to bring the pH up and the magnesium is on the low side.
Applications
- Lawn & Soil
- Garden Beds & Planting
- Pasture & Field
- Sports Fields
- Correcting Acidic Soil
- Supplying Calcium & Magnesium
Why It Works
Raises pH and feeds magnesium at the same time.
Dolomitic lime is calcium carbonate and magnesium carbonate bonded together in the rock. Once it’s worked into the soil, it dissolves slowly in soil moisture and neutralizes the acidity that holds plants back. As the pH comes up toward the range most grass, crops, and garden plants prefer, nutrients already in the ground become more available, and the lime drops in calcium and magnesium as it goes.
The magnesium is the reason you’d pick dolomitic over plain calcitic lime. If a soil test shows your magnesium is low to marginal, this material brings it up while it corrects the pH. Particle size matters here: the finer material starts working soon after it’s tilled in, while the coarser bits keep dissolving and releasing over the next few seasons, so one application keeps doing its job for a while.
