Description

Oldcastle Pro-Select 白云石粉是一种用于草坪和花园的白云石土壤改良剂,旨在纠正土壤 pH 值并解决土壤酸度问题,以便植物能够更有效地吸收养分。

这种园艺石灰是一种精细的粉状石灰石产品,专为处理酸性土壤而设计,可轻松改良土壤。它有助于中和酸性,从而营造更平衡的根系环境,并提高土壤整体养分有效性。对于希望获得可靠、专业级石灰改良剂,又不想让土壤改良方案变得复杂的园丁和草坪管理人员来说,这是一款实用之选。

由于它是白云石粉,因此还能提供钙和镁这两种次要元素——这两种营养元素对许多土壤维持稳固结构和促进植物稳定生长至关重要。钙在土壤结构和根系功能中发挥着关键作用,而镁则支持与植物健康生长相关的核心生理过程。综上所述,如果您希望现有施肥方案的效果更加稳定,尤其是在酸性土壤会阻碍植物生长的地区,Oldcastle Pro-Select 白云石粉无疑是一个理想的选择。

Oldcastle Pro-Select 是一款经济实惠的酸性土壤改良剂,能够为草坪和观赏景观带来专业级的效果。它常用于大面积草坪和花园,因为在这些地方,长期持续的土壤 pH 值调节至关重要,而且种植者希望使用一种天然石灰石,并能将其轻松融入标准的土壤养护流程中。如果您发现土壤出现酸性过强的迹象——例如植物活力下降、生长不均匀或难以保持稳定的生长状态——那么这种粉状白云石石灰石是改善土壤酸碱度、使其恢复到更适宜耕作范围的有效方法。

成分说明:这是一种白云石灰石产品,由与钙和镁(包括碳酸钙和碳酸镁)相关的石灰石碳酸盐构成。这些碳酸盐矿物赋予了白云石灰石灰的石灰化作用以及钙镁元素,使其区别于方解石石灰。

对于希望使用以土壤 pH 值校正、土壤酸度中和以及钙镁补充为重点的草坪和花园石灰的种植者和园林绿化师来说,这款产品非常合适——尤其适合那些以长期土壤改良为目标的户外土壤种植环境。

How To Use

How to Use Dolomitic Limestone With a Basic Soil pH Tester

Check your soil pH first
Use your soil pH tester in a few spots (not just one). Soil pH can vary across a lawn or garden bed, so taking multiple readings gives you a more reliable average.

Decide if you actually need to raise pH
If your pH is already in a good range for what you’re growing, you may not need to add anything. If your pH reads too acidic, this type of soil amendment is typically used to gently move pH upward over time.

Apply a small amount first (don’t try to “fix it” in one shot)
Because a basic pH tester doesn’t calculate an application rate, the best method is gradual adjustment:
Spread a light, even layer over the area (or mix a small amount into potting mix for containers).
Avoid heavy piles or thick coverage in one spot.

Water in and wait
Water helps move it into the root zone and begins the soil change process. pH adjustment isn’t instant—soil takes time to respond.

Re-test later, then adjust if needed
After it has had time to work, re-test your soil pH again:
If the pH is moving in the right direction but still low, you can repeat a light application.
If the pH has reached a healthy range, stop and maintain.

Avoid over-correcting
Raising pH too much can create new nutrient issues. The “apply a little and re-test” method keeps your garden in the safe zone and helps you dial in results over time.

Best practices for different gardening uses

Lawns
Apply evenly using a spreader for consistent coverage.
Re-test in different spots before re-applying.

Garden beds & raised beds
If you’re prepping a bed, mixing into the top layer gives more consistent results.
If plants are already growing, apply lightly to the surface and water in.

Containers & potting mix
Mix thoroughly through the potting mix (don’t leave it layered).
Adjust slowly and re-test—containers can change pH faster than outdoor soil.

Warnings & Safety

Warning – Important Safety Information

This product may cause mild skin irritation and eye irritation. Avoid unnecessary contact with skin, eyes, and clothing. Use only as directed.

General safety precautions

Read and follow all instructions on the product label and any accompanying documentation before use. Keep out of reach of children and pets. Do not ingest. Avoid breathing vapours, mist, or dust that may be generated during handling or use.

Wear appropriate personal protective equipment (PPE), such as protective gloves, long sleeves, long pants and closed-toe footwear. When there is a risk of splashing or airborne particles, use safety glasses or other suitable eye and face protection.

First aid – skin contact

IF ON SKIN OR HAIR: Remove contaminated clothing immediately. Rinse skin with clean water for several minutes, then wash with mild soap and water. If irritation or redness develops and persists, seek medical attention. Wash contaminated clothing before reuse.

First aid – eye contact

IF IN EYES: Rinse cautiously with clean water for several minutes, keeping eyelids open. Remove contact lenses if present and easy to do. Continue rinsing. If irritation persists, obtain medical advice.

First aid – ingestion and inhalation

IF SWALLOWED: Rinse mouth thoroughly with water. Do not induce vomiting unless instructed by a medical professional. Seek medical attention if you feel unwell.

IF INHALED: Move the person to fresh air and keep them comfortable for breathing. If coughing, breathing difficulty, dizziness or other symptoms occur, seek medical assistance.

Frequently Asked Questions

Why is calcium important for plant growth?

Calcium is important because it builds and stabilizes plant cells as they form, acting as the structural support that keeps new growth strong and functional. Unlike other nutrients that drive color or speed of growth, calcium’s role is unique because it controls cell wall strength and membrane stability, making it essential for healthy roots, shoots, and long-term plant resilience rather than quick visual results.

What does dolomite do for plants in the root zone?

Dolomite gently raises and stabilizes pH while supplying calcium and magnesium, helping roots absorb nutrients more consistently and supporting strong new growth and greener leaves. It’s unique because it buffers acidity and feeds two key minerals at the same time, unlike materials that only change pH or only provide a single nutrient.

Why is neutralizing value (CaCO3) important in plant growing?

Neutralizing value (CaCO3) is important because it tells you how strongly a material can neutralize acidity and stabilize root-zone pH, which directly controls nutrient availability and healthy root function—and it’s unique because it measures long-term acid-neutralizing capacity, not just a single pH reading.

What does “passes 10 mesh” mean for a garden soil amendment?

It means the material is processed to a more uniform particle size, which helps it spread more evenly, mix into soil more consistently, and perform more predictably across garden beds, lawns, and planting areas.

What does “passes 100 mesh” mean and why do gardeners care?

It indicates a portion of the material is very finely processed, which increases surface area—often helping the amendment begin working sooner in the soil and creating faster, more noticeable improvements in the root zone.

What are common signs of magnesium deficiency in plants?

A classic sign is yellowing between the leaf veins (often called interveinal chlorosis), usually starting on older leaves first. In more advanced cases, leaves may look pale, weak, or begin to decline as the plant struggles to maintain healthy growth.
