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

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.
