Description

A soil amendment for dry, acidic and nutrient poor soils.

Biochar is biomass (any organic material such as wood) that is produced (pyrolysis) in an oxygen-free environment. At 350°C, all the non-carbon elements in the biomass evaporate. The only solid residue is carbon (charcoal).When viewed under a microscope, one sees that the carbon looks like a sponge with millions of "chambers". The surface of the walls of 1 gram biochar is 50 to 500 m² (as large as 2 tennis courts).This porous structure and high specific surface area gives it the ability to attract and retain water and water-soluble nutrients (hygroscopic).

Benefits

• Increase water retention in the soil up to 200% (Reduce irrigation requirements)
• Improve the quality of soil water
• Reduce soil acidity
• Increase cat-ion exchange capacity in soils
• Reduce the leaching of soluble nutrients (Reduce fertilizer requirements)
• Reduce the leaching of E-coli through sandy soils
• Improve the habitat for beneficial micro-organisms (Because it remains in the soil for long, the organisms that have settled into the soil do not perish easily when there is drought or heat stress)
• Provide protection against some foliar and soil-borne diseases
• Improve the health of the plants

• Planters/pots: Add 5% biochar to planting mix. 1 teaspoon per pot. Apply as close to the roots of the plants as possible
• Garden beds: 100 gram per square meter, work into soil
• Loosen lawn first and then add 10 ml per square meter
• Add biochar to compost heap

This green container is not pure biochar, but a mixture of biochar (33.3%) + vermicast (33.3%) cow manure (33.3%) = 5 times better than ordinary compost.
