If your lawn is struggling with heavy moss and your garden plants are showing yellow leaves despite regular watering, an acidic, calcium-deficient soil is likely the culprit. Compo Gartenkraft Dolomite Lime solves this issue with a powerful dual-action formula: it neutralizes harmful soil acidity while delivering vital calcium and magnesium in a single application. If you are looking to buy premium dolomite lime, this is your professional solution to restore a perfectly balanced, vibrant home garden.

🌱 Dual Cal-Mag Complex: Safely stabilizes soil pH levels and unlocks locked-up nutrients for immediate root absorption.
⚡ Combats Moss & Lawn Yellowing: High-purity magnesium fuels chlorophyll production, restoring a deep, vibrant green to your turf.
🧪 Structural Plant Strength: Rich in natural calcium to reinforce plant cell walls, significantly boosting drought and disease resistance.
🌿 Dust-Free Application: Specially calibrated, fine granules ensure clean, even distribution by hand or mechanical push-spreader.
❄️ Weather-Flexible Season Start: Highly versatile and effective for late autumn soil maintenance or early spring garden prep.

A dropping soil pH level acts as a silent bottleneck in your garden, locking away vital nutrients and leading to stunted growth, patchy turf, and aggressive moss invasions. Compo Gartenkraft Dolomite Lime Cal-Mag actively counteracts this subsurface deterioration by neutralizing soil acidity and re-establishing the ideal calcium-to-magnesium ratio. This granular magnesium limestone safely prevents nutrient lockouts caused by artificial fertilization or acidic rainfall, making it the top choice for growers seeking to buy high-efficiency soil conditioners.

The Agronomic Power of Combined Calcium & Magnesium

Nutrient Mobilization: Bringing your soil to an optimal pH level releases bound-up essential nutrients like phosphorus and nitrogen, making them fully bioavailable again.
Structural Soil Optimization: Active calcium ions bridge clay and organic matter to form stable clay-humus complexes. This creates a crumbly, well-aerated soil structure and prevents compaction.
Sustained Root Protection: As a natural carbonate lime, it dissolves gradually based on moisture and soil biological activity, virtually eliminating the risk of accidental chemical over-liming.

Dolomite Lime Compared: Choosing the Right Agricultural Lime

Selecting the correct type of garden lime depends on your soil texture, required reaction speed, and specific crop deficiencies. While standard agricultural limes only adjust acidity, dolomite provides a crucial nutritional secondary benefit for chlorosis-prone plants.

Type of Lime	Reaction Speed	Soil Suitability & Key Secondary Benefit	Magnesium Content
Dolomite Lime (Cal-Mag)	Steady / Sustained: Gentle, long-term breakdown over several weeks.	Perfect for light sandy to heavy soils; actively cures and prevents magnesium deficiencies.	Very High: Naturally derived from magnesium-rich carbonate deposits.
Garden Lime (Calcium Carbonate)	Moderate: Relies purely on physical water solubility within the soil profile.	Good for general maintenance on lawns that already boast optimal magnesium levels.	None or only trace elements.
Quicklime / Hydrated Lime	Extremly Fast: Highly reactive, causing immediate chemical shifts.	Strictly restricted to heavy, compacted industrial clay soils. High risk of root burn.	Usually pure calcium oxide with zero magnesium value.

The Science: Why Your Soil Needs Both Elements Simultaneously

The unique advantage of Compo Cal-Mag lies in the biological synergy between its two main mineral components:

Cellular Fortification via Calcium: Calcium carbonation strengthens plant tissues by reinforcing cell walls. This directly regulates internal water pressure, preventing blossom end rot in tomatoes and boosting resilience against heat stress.
Photosynthetic Drive via Magnesium: Magnesium serves as the absolute central atom of the chlorophyll molecule. Without a steady supply, plants cannot capture sunlight efficiently, leading to faded leaves and severe energy loss.
Microbial Activation: A stable, near-neutral pH level creates a hospitable environment for earthworms and beneficial soil bacteria. This accelerates organic matter decomposition, turning dead waste into rich, fertile humus.

Best Uses:

Recommended Applications

Routine maintenance of moss-ridden, sour, or heavily shaded lawns
Bed preparation for calcium-loving vegetable crops (e.g., brassicas, tomatoes, peppers)
Boosting nutrient absorption around established fruit orchards and berry patches
Counteracting the acidifying side-effects of bark mulch and peat-based substrates

Limitations:

Not Recommended For

Acid-loving ericaceous plants (e.g., rhododendrons, azaleas, blueberries)
Naturally alkaline garden soils showing a steady pH level above 7.2
Direct mixing with freshly applied ammonium fertilizers (causes volatile nitrogen loss)
Soil-free hydroponic setups or closed indoor recirculating systems

Application Rates & Guidelines by Soil Type

For optimal results, spread the fine granules evenly across dry lawns or beds. Using a calibrated broadcast spreader ensures a uniform pattern. Lightly raking the granules into the top few centimeters of garden beds significantly accelerates the pH-neutralizing effect.

Recommended Annual Maintenance Dosage:

Light, Sandy Soils: approx. 6–8 kg per 100 m²
Medium, Loamy Soils: approx. 10–14 kg per 100 m²
Heavy, Clay Soils: approx. 15–18 kg per 100 m²
Restorative Liming (For severely sour soils): Based on a prior pH test, dosage can be safely increased up to 25 kg/100 m² for sandy profiles and up to 50 kg/100 m² for heavy clays to regenerate the soil biology.

Frequently Asked Questions (FAQ)

How do I know if my garden soil actually needs lime?
Severe moss growth, patches of weeds like sheep sorrel, and general stunted plant growth are clear indicators of high soil acidity. To get precise data, we highly recommend running a quick DIY pH test before application.
Can I apply garden lime and lawn fertilizer on the same day?
No, you must wait at least 3 to 4 weeks between liming your lawn and applying a high-nitrogen fertilizer. If they mix directly, the lime reacts with the fertilizer's ammonium, turning your valuable nitrogen into ammonia gas that evaporates uselessly into the air.
Is dolomite lime safe for pets and wildlife?
Yes, kohlensaurer dolomite lime is a completely natural, non-toxic crushed mineral product. Once the granules have been thoroughly watered into the lawn and are no longer sitting loosely on the grass blades, pets can safely return to the area.
Why is lime harmful to rhododendrons and blueberries?
These species are acid-loving plants that physically require a low-pH environment to absorb iron and other micronutrients. Raising the soil pH with lime completely blocks their root intake, resulting in lethal leaf yellowing known as iron chlorosis.
