Lime stone as a soil improver

What is the function of lime stone?

Rainwater is fairly acidic and especially sand and clay soils suffer from this. Lime stone prevents acidification of the soil, improves the structure of the clay soil, fights moss and helps the plants absorb fertilizers. Lime promotes plant growth and prevents plant diseases. Basically applies; too little lime is more harmful than too much lime.

Adding lime makes a clay soil more airy. This means there is less chance of silting up in the ground. In addition, lime helps plants to absorb nutrients.

Lime stone and ph-numbers

When soil is too acidic, lime is needed. With lime, the ph (potentie hydrogenii = acidity) value increases. This means that the acidity of the soil decreases.

With too much lime, the pH becomes too high.

PH value = value from 0 to 14. Is the pH lower than 7? Then there is acid soil. If the pH value is higher than 7, then it is a basic/alkaline soil. For example, soap, soda and ammonia are basic substances.

How and when to scatter lime stone?

The best times to scatter lime stone are in early spring and late autumn in rainy weather. It is best to sprinkle lime when it is above 5 degrees at night. Even spreading is recommended, because this is ‘nicer’ for the soil.

Lime cannot be combined with fertilizers. This combination releases ammonia and is toxic to most plants. Have you sprinkled lime and do you also want to fertilize? Wait about 3 weeks before spreading fertilizer, then it won’t hurt anymore.

For what ground how much lime stone?

For sand and loam soil, it is recommended to sprinkle 1kg of lime per 10 square meters with a frequency of 2x per year. This soil needs more lime than clay soil.

The following applies to clay and loess (loess is a soil structure smaller than a grain of sand); 1.5 kg per 10 square meters 1x per year.

To raise the soil 0.1 percent, you need 5 kg of garden lime per 100m2.

Do you have a fruit tree in your garden? You give high stem fruit from 2 to 3 years old a few handfuls every year. If it is now an older fruit tree (from 25 years), give 1 kilo of lime every year.

Lime loving plants

Examples of lime-loving plants are; boxwood, butterfly bush, clematis, grape, lavender, lilac, lawn, roses, yew, rosemary, fruit trees, butterfly bush, roses, Christmas rose, deer hay and clematis.

There are also vegetables that require lime, such as leafy vegetables, cabbages, tomatoes, eggplant and peppers.

Acid loving plants

There are also plants that prefer a more acidic soil. It is not recommended to use lime with these plants. Plants that dislike lime include hydrangea, azalea, heather, rhododendron, cranberry, skimmia, camellia, and broom.

Bio lime stone

The number of brands of lime is gigantic. There are many varieties that barely work or that are so fine that it blows in all directions.

Many types of lime contain no magnesium (an indispensable element for plants, it is the building block for chlorophyll and is therefore essential for photosynthesis). So you can pay attention to this when you buy lime.

Bio-lime is quickly soluble and does not dust. It also contains a percentage of magnesium, which gives the plants a deep green color. This organic lime is also available from Marvy Green.

Determine the dosage

Soil testing is often required for a correct dosage. You can have the pH value determined at many garden centers. Take some soil from the garden of acid-loving and lime-loving plants.

There are also strip tests to determine the acidity yourself. Strips of litmus (resinous substance from the ficus or from lichens) can be used as an indicator. Blue litmus paper for an acidic solution, red for basic.
