Description

Oldcastle Pro-Select 白云石粉状石灰是一种用于草坪和花园的白云石石灰土壤改良剂,旨在纠正土壤pH值并解决土壤酸度问题,从而使植物更有效地吸收养分。

这种园艺石灰是一种细小的粉状石灰产品,适用于在酸性土壤条件下进行直接的土壤调理。通过帮助中和酸度,它支持更平衡的根区环境,并可以改善土壤中养分的整体有效性。对于希望获得可靠的专业级石灰材料,而又不想使他们的土壤方案变得复杂的园丁和草坪管理者来说,它是一个实用的选择。

因为它是一种白云石石灰,它还提供次要元素钙和镁——这两种养分是许多土壤结构强健和植物稳定发育所依赖的。钙在土壤结构和根系功能中起着关键作用,而镁则支持与健康绿色生长相关的核心植物过程。总而言之,这些益处使 Oldcastle Pro-Select 白云石粉状石灰成为一个可靠的选择,当您希望现有施肥计划表现更稳定时,尤其是在酸度可能阻碍植物生长的地区。

Oldcastle Pro-Select 被定位为一种经济型酸性土壤改良剂,同时仍能为草坪和观赏景观提供专业效果。它通常被选择用于广泛的草坪和花园覆盖,在这些地方,持续的土壤pH值校正至关重要,并且种植者希望使用一种能够干净地融入标准土壤护理程序的天然石灰投入。如果您已经看到您的土壤有趋于酸性的迹象——例如活力下降、生长不均匀或难以保持一致的性能——这种类型的粉状白云石石灰是一种有针对性的方法,可以将土壤恢复到更适合植物生长的范围。

事实层:这是一种白云石石灰产品,由与钙和镁相关的石灰碳酸盐(包括碳酸钙和碳酸镁)构成。这些碳酸盐矿物提供了石灰作用以及钙和镁的贡献,这使得白云石石灰与方解石石灰不同。

本产品非常适合希望通过石灰来纠正土壤pH值、中和土壤酸度以及支持钙和镁的种植者和景观设计师——特别是在以土壤为基础的户外环境中,长期土壤调理是目标的一部分。

产品优点:营养生长阶段;开花阶段;室内;室外;定期浇水;土壤;无土;有机;土壤酸度支持;更好养分吸收;平衡根区;钙支持;镁支持;土壤结构支持;性能稳定;易于使用的粉末形式。

保证分析:钙 (Ca): 20.0%;镁 (Mg): 10.0%;中和值 (CaCO3): 90.0%;细度通过 10 目泰勒筛:99.0%;细度通过 100 目泰勒筛:42.0%。

使用方法:如何使用白云石石灰和基本土壤pH测试仪 - 首先检查您的土壤pH值 在几个地方(不只是一个地方)使用您的土壤pH测试仪。土壤pH值在草坪或花园床中可能会有所不同,因此进行多次读数可以为您提供更可靠的平均值。确定您是否真的需要提高pH值 如果您的pH值已经处于适合您种植的良好范围,您可能不需要添加任何东西。如果您的pH值读数过酸,这种类型的土壤改良剂通常用于随着时间的推移缓慢提高pH值。首先少量施用(不要试图一次性“修复”) 因为基本的pH测试仪不计算施用量,所以最好的方法是逐渐调整:在区域上撒上一层薄而均匀的层(或将少量混合到用于容器的盆栽土中)。避免在一个地方堆积过重或覆盖过厚。浇水并等待 水有助于将其移入根区并开始土壤变化过程。pH值调整不是即时的——土壤需要时间来响应。稍后重新测试,然后根据需要调整 在它有时间发挥作用后,再次重新测试您的土壤pH值:如果pH值朝着正确的方向移动但仍然偏低,您可以重复轻度施用。如果pH值已达到健康范围,则停止并保持。避免过度校正 过度提高pH值可能会产生新的养分问题。“少量施用和重新测试”的方法可以使您的花园保持在安全区域,并帮助您随着时间的推移调整结果;不同园艺用途的最佳实践 - 草坪 使用撒播器均匀施用,以获得一致的覆盖。在重新施用前在不同地点重新测试。花园床和高架床 如果您正在准备花床,将其混合到顶层会产生更一致的结果。如果植物已经生长,轻轻撒在表面并浇水。容器和盆栽土 彻底混合到盆栽土中(不要分层)。缓慢调整并重新测试——容器的pH值变化可能比室外土壤快。

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.

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.

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 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.

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.

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.
