Although this technique dates back more than 2500 years, contemporary agronomists have only recently discovered its immense potential. In our opinion, biochar is nothing less than the missing (and now found!) link in living soils .

Optimal ratio to be achieved gradually (1 to 5 years), according to several application methods: 1 kg/1 m2 of soil (consult the application guide ).

Fine particle size is more easily introduced into small or narrow containers (in multi-cell trays, for example) and is recommended for "living mixtures" (biochar + compost).

• The ultra-porous structure of the carbonized residues of biochar acts like a sponge, trapping nutrients very effectively, retaining water and promoting the maintenance of microorganisms essential to a living soil.
• Biochar represents a future solution for sustainably improving the yield of agricultural land, in addition to being an excellent way to sequester carbon in the soil.

Earthworm castings (Organic Vermicompost Biocompost) are ideal for indoor use, as they are virtually odorless and their fine texture easily incorporates into potting soils. They are also suitable for plants in vegetable gardens, flower beds, and lawns.

• Transplanting, repotting and preparing planters: Mix one part worm manure with 3 parts commercial potting soil.
• Sowing: Once your seeds are placed in the furrows, sprinkle them with worm manure (5 mm) then close the furrows with soil.
• Transplanting in the garden: Place a large handful of worm manure in the hole before putting the plant in.
• Shrubs, vines, perennials, etc.: Sprinkle 5 mm of worm manure at the base of the plants every two months.
• Planters, flower pots, and houseplants: Pour 2 cm of potting soil into the bottom of the container and mix in a handful of worm castings. Then, every two months, sprinkle 5 mm of worm castings over the surface of the soil before watering.
• Lawn: In spring, mid-summer and when closing the field in autumn, sprinkle about 2 L of worm manure per ^m2 of lawn.
• Laying turf rolls: For faster rooting, spread about 2 L of worm manure per ^m2 , lay the turf rolls and sprinkle the rolls with about 2 L of worm manure per ^m2 .
• Manure juice: Once a week, add a handful of worm manure to 5 or 10 liters of water, mix everything together and let it steep for about 8 hours before using the resulting juice to water your plants.
• Lawn repair: When yellow patches appear on the lawn, sprinkle them generously with worm manure and water them with compost juice.
• NPK: 1-0.5-1

Marine calcium used in horticulture is a natural, calcium-rich soil amendment obtained from marine shellfish, such as oyster or mussel shells. It is widely valued for its ability to improve soil structure, correct calcium deficiencies, and promote healthy plant growth. Furthermore, it contributes to soil regeneration while respecting the marine ecosystem through responsible harvesting practices.

Gaia Green glacial rock dust is rich in natural silica and is an excellent source of calcium, iron, magnesium, potassium, and trace elements. It improves soil structure, drainage, water retention, and cation exchange capacity.

• Glacial rock dust allows the soil to recreate the colloids (minerals and humus) necessary to improve soil structure, moisture retention properties, nutrient availability and bacterial action.
• When the right balance is achieved, organic matter is transformed into humus and the soil becomes a favorable environment for a multitude of beneficial molds, fungi, bacteria and earthworms.
• 100% Authentic Canadian Glacial Moraine
• A unique mineral product for vegetable gardens, flower beds, transplanting and composting.
• For vegetable gardens and flower beds, incorporate up to 10 kg (22 lb) per 10 ^m² (107 sq ^ft ) into the top layer of soil once a year or as needed.

Vermiculite is obtained by heating a mica rock to between 900 and 1000 °C. Under such heat, the rock expands and becomes very light. With a neutral pH and hydrophilic properties, it is a prized ingredient in growing media for seedlings, cuttings, and flowering plants.

• Very light, clean and odorless expanded micaceous mineral.
• Mixed with potting soil, vermiculite improves aeration and drainage, which helps root development.
• It helps to retain soil moisture to reduce watering needs.
• It promotes nutrient retention in potting soil mixes.
• Ideal for seed germination

The advantage of dolomitic lime over ordinary lime is its higher calcium and magnesium content, two essential nutrients for vegetable crops. Regular use of dolomitic lime helps reduce soil acidity, facilitating nutrient uptake by plants.

• A mixture of calcium carbonate and magnesium carbonate.
• Neutralizes overly acidic soils to aid in the assimilation of nutrients.
• Promotes better growth of beneficial soil bacteria.
• Excellent choice for application on lawns, flower beds and vegetable gardens.

This natural, additive-free substrate is made entirely of coconut fibers and contains no mineral salts. It can replace peat moss in potting mixes.

• pH neutral
• 100% natural.
• Improves soil aeration and drainage.
• Adds organic matter to the soil.
• Suitable for all plants.

Produced from a renewable resource, unlike limestone extracted from the ground which has a comparable effect, oyster shell flour helps to increase the pH of the soil.

• Excellent source of slow-release calcium.
• A single application can affect the chemical properties of the soil for several years.
• An excellent choice for all vegetable gardens, flower beds, lawns and trees that suffer from soil with a pH that is too acidic.
• Approved for organic farming by Ecocert.
• Guaranteed minimum analysis: Calcium 36.0% - Neutralizing value (equivalent to CaCO3) 96.0% - Passes through a 100-mesh TYLER sieve 30.0%
