Down to Earth Dolomite Lime | 5lb - OMRI Listed - (Case of 6)

OMRI Listed Granular Dolomite Lime for Raising Soil pH and Supplying Calcium (5lb)

Down to Earth Dolomite Lime is an OMRI Listed granular lime that sweetens soil (raises pH) to improve plant growth and fertilizer performance. Ground to an ultra-fine powder and prilled into uniform granules for easy spreading, it allows for rapid reaction time once applied to soils and lawns. It supplies both calcium and magnesium.

The 5lb size (Case of 6) is convenient for home gardeners who apply dolomite lime for periodic soil pH management, lawn care, or targeted calcium and magnesium supplementation.

Key Features & Benefits

• Raises Soil pH — Sweetens acidic soils to improve plant growth and maximize fertilizer effectiveness.
• OMRI Listed — Approved for certified organic production.
• Supplies Calcium and Magnesium — Provides two essential secondary nutrients in a single application.
• Uniform Prilled Granules — Ground to ultra-fine powder and prilled for easy, even spreading.
• Rapid Reaction Time — Fast-acting formulation that begins affecting soil pH quickly after application.

Who Should Use Down to Earth Dolomite Lime

Dolomite Lime suits organic gardeners, lawn care practitioners, and growers whose soils are too acidic and need pH adjustment. It is particularly useful for those who want to supply both calcium and magnesium alongside pH correction in a single amendment, and for those who regularly manage soil pH in vegetable gardens or lawns.

Soil pH and Plant Nutrition

Soil pH affects nutrient availability to plants. When soil is too acidic, certain nutrients become less available or may interfere with plant uptake. Raising soil pH with lime can improve the availability of phosphorus, calcium, and magnesium, and make fertilizers more effective. Dolomite lime is distinct from calcitic lime in that it provides both calcium and magnesium — an advantage in soils where both nutrients are needed. Test soil pH before applying lime and follow label recommendations for rates.

Frequently Asked Questions

What is the difference between dolomite lime and calcitic lime?

Dolomite lime contains both calcium and magnesium carbonate, while calcitic lime contains primarily calcium carbonate. Dolomite lime is preferred when soils need both calcium and magnesium, while calcitic lime is used when only calcium and pH correction are needed.

Is Down to Earth Dolomite Lime OMRI Listed?

Yes. It is OMRI Listed and appropriate for certified organic production.

Why does raising soil pH improve plant growth?

Many nutrients, including phosphorus, calcium, and magnesium, are less available to plants in highly acidic soils. Raising pH into the optimal range improves nutrient availability and makes applied fertilizers more effective.

How fast does Dolomite Lime act in the soil?

The ultra-fine powder inside each prilled granule allows for rapid reaction time once applied to soil and watered in, making it faster-acting than coarser lime products.

Should I test my soil before applying Dolomite Lime?

Yes. A soil pH test is recommended before applying lime so you can determine the current pH and calculate the appropriate application rate. Over-liming can raise pH too high, which can also reduce nutrient availability.
