Calcium is a mild-action organic calcium of natural origin (fossilized algae from Lithothamnium calcareum harvested from the ocean) that is ideally suited for the deacidification of all soils. Additionally, this lime makes heavy soils easier to cultivate.

This very fine and mild calcium always acts without any risk of burning and can be used in agriculture, professional cultivation, and amateur gardening. Calcium is rich in trace elements, essential for strong and healthy plants. Thanks to its internal action, calcium is very stimulating for the microbial life of the soil.
