5 Litre bucket
100% Bio Char
Soil enhancer and conditioner for healthier, more productive plant growth. Ideal for flowers, herbs, vegetables and hanging baskets.
How to use Bio Char
Tubs and Pots - apply 10% on Biochar to 90% compost or top soil. Mix in well.
Lay turf - apply BioChar to topsoil. Rake in 1Kg per one cubic metre turfing area and water well.
Seeding - Apply Biochar to bottom of seedling trenches, place and cover seeds. Water well.
More about BioChar
Biochar is defined simply as charcoal that is used for agricultural purposes. It it created using a pyrolysis process, heating biomass in a low oxygen environment. Once the pyrolysis reaction has begun, it is self-sustaining, requiring no outside energy input. Byproducts of the process include syngas (H2 + CO), minor quantities of methane (CH4), tars, organic acids and excess heat.
Once it is produced, biochar is spread on agricultural fields and incorporated into the top layer of soil. Biochar has many agricultural benefits. It increases crop yields, sometimes substantially if the soil is in poor condition. It helps to prevent fertilizer runoff and leeching, allowing the use of less fertilizers and diminishing agricultural pollution to the surrounding environment. And it retains moisture, helping plants through periods of drought more easily. Most importantly, it replenishes exhausted or marginal soils with organic carbon and fosters the growth of soil microbes essential for nutrient absorption, particularly mycorrhizal fungi.
The latest use is to mix amongst ash tree rootes to help prevent ash dieback disease ... as seen on BBC Countryfile February 21 2016.
Studies have indicated that the carbon in biochar remains stable for millenia, providing a simple, sustainable means to sequester historic carbon emissions that is technologically feasible in developed or developing countries alike. The syngas and excess heat can be used directly or employed to produce a variety of biofuels.
When biochar is created from biomass, approximately 50% of the carbon that the plants absorbed as CO2 from the atmosphere is ?fixed? in the charcoal. As a material, the carbon in charcoal is largely inert, showing a relative lack of reactivity both chemically and biologically, and so it is strongly resistant to decomposition. Research scientists have found charcoal particles as old as 400 million years in sediment layers from wildfires that occurred when plant life first began on earth.
