Description

Calcitic Lime is made up of 80 – 90 % calcium carbonate, and also contains small amounts of trace elements, such as magnesium, potassium, silicon and sulphur.

Calcitic lime has long been the preferred treatment for acidic soil. A thorough application of pulverized limestone tilled into the soil raises the pH to a neutral level, increasing crop yields and improving overall soil health. In addition to neutralizing pH, lime also encourages the growth of micro-organisms that contribute to plant health. With the combination of helpful micro-organisms and pH balanced soil, plants and crops will thrive.

The main “ingredient” in calcitic lime is calcium carbonate, which counteracts the acidification of field soil. Acidification is the natural result of nitrogen heavy fertilizing practices. By adding a lime treatment, you can undo the damage caused by nitrogen treatments without counteracting the benefits.

Benefits

• Effectively balances the pH soil.
• Natural source of Calcium.
• Contains trace elements that encourages growth of beneficial. microorganisms that contribute to plant health.
• Calcitic lime works effectively, even with one treatment.
• Faster acting but with long lasting effects.
• Calcitic lime works pH's the soil faster than dolomite lime: Calcium carbonate is better at balancing the pH of soils than magnesium carbonate, and calcitic lime contains much higher levels of calcium carbonate than dolomite lime.
• Improves the uptake of nutrients.

How to use

5ml = 1 teaspoon | 15ml = 1 Tablespoon | 240ml = 1 Cup

Organic amendment

Soil Mix: Pre pH buffer soil

• Dosage:
• 3ml Calcitic Lime per 1L substrate
  
• 90ml Calcitic Lime per 30L substrate
  
• Dosages can vary significantly depending on soil substrate
  

• Frequency: When mixing/revitalizing a substrate
• Application: 
• Get a container or set a tarp on the ground
• Add the substrate, Dolomite Lime and other soil amendments
• Mix well and water lightly
• Cover the soil to avoid pests and keep soil from drying out
• Recommended to let the soil sit for approx. 2 months before use

Soil Mix: To increase the pH by 1 unit

• Dosage:
  

• If you have an acidic soil mix (50% peat moss & 50% vermiculite) and you need to increase your pH from 4.5pH to 5.5pH

• 4ml Calcitic Lime per 1L substrate
• 120ml Calcitic Lime per 30L substrate
• Dosages can vary significantly depending on soil substrate

• Frequency: When mixing/revitalizing a substrate
• Application: 
• Get a container or set a tarp on the ground
• Add the substrate, Calcitic Lime and other soil amendments
• Mix well and water lightly
• Cover the soil to avoid pests and keep soil from drying out
• Recommended to let the soil sit for approx. 2 months before use

To Change the Soil's pH in Garden Beds

• Calcitic lime increases the pH of soil, making it more alkaline. Determine how much is needed, dependent on the current pH of your soil, and spread calcitic lime on top layer of soil.
• Per 1m³ of soil apply 2800g / 2L of calcitic lime to raise the pH by 1 point. 
• The medium pH typically takes at least two days to stabilize from the limestone addition alone and may take up to 2 weeks to be fully reacted. Wait before reapplication.

 1L of Calcitic Lime (approx. 1.3kg)

 

Helpful tip:

Lime dust may cause irritation to skin, eyes and respiratory tract. Handle with care - use a dust mask.
