What is Biochar?

Have you heard of biochar? This “new” organic may be a safe, effective soil amendment with a plethora of advantages from increasing water retention and soil microbes to reducing greenhouse emission emissions. But what’s it, and the way does it work? Biochar is brief for “biomass charcoal.” Unlike mined charcoal, it’s made by pyrolysis (decomposition caused by high temperatures). Organic materials (for Black Owl Biochar, this suggests untreated wood waste) are heated at over 1000°C in an oxygen-free environment. The result’s biochar, a specialized sort of charcoal whose structure is microscopically extremely porous. This porous surface is what gives biochar its numerous benefits within the garden because it creates sites to carry nutrients and moisture, and habitat for microorganisms. Although it’s going to appear to be a replacement thing, the essential process has been used for over 7000 years within the Amazon Basin of South America, where it’s called Terra Preta or “black soil.” These ancient fields of biochar are still incredibly fertile. Today’s technology creates an identical product but using cleaner-burning machines. In fact, it’s due to the improved technology that biochar is touted as a possible solution to greenhouse emission emissions. There are numerous methods to eliminate biomass waste getting used today, like composting, incineration, and slash-and-burn. Of all the various methods of waste disposal, creating biochar is currently considered to be the foremost environmentally friendly. it’s the sole method that doesn’t release greenhouse gases into the atmosphere, and therefore the resulting product sequesters atmospheric carbon within the soil for thousands of years. Thus, by using biochar in your garden, you’re supporting a replacement technology with the potential to form an enormous difference for Mother Earth. Our Black Owl Biochar takes this to a good higher standard. Their product is formed with especially high temperatures, in order that it doesn’t contain PAHs (Polycyclic Aromatic Hydrocarbons) or PCBs (Polychlorinated Biphenyl). Even organic certification doesn’t require testing for these compounds.

What Does Biochar neutralize the Soil?

Chemically, biochar doesn’t add any nutrients to the soil. Its benefits come primarily from its unique structure. Although it’s a source of carbon, it can take thousands of years to interrupt down fully. However, it can improve organic matter content by creating a far better soil for organic interest build up.

Biochar’s porous structure provides many benefits:

It attracts and retains water molecules, thus improving the water holding capacity of the soil. it’s especially useful during this respect for areas with low rainfall and soils with poor water retention.

It decreases nutrient leaching and increases cation exchange capacity (CEC) so nutrients are more available for plant roots to require up.

Biochar features a charge that binds to nutrients like calcium, potassium, and magnesium. This also leads to reduced soil acidity (a higher pH).

The nutrient binding means less fertilizer is required. Since there’s less run-off of nutrients, it’s safer for groundwater and surface water too.

Biochar Benefits Soil Biology

The porous structure also creates the right habitat for soil microbes and beneficial fungi to flourish. Although the microorganisms will eventually enter the biochar, you’ll see a good bigger benefit if you “pre-charge” or “activate” your biochar (this process is additionally sometimes called inoculating, maturing, culturing, or charging the biochar). This optional step is completed before incorporating the biochar into your garden and has the additional advantage of preventing excessive nutrient binding (where numerous nutrients become bound up with the biochar within the soil that not enough are available to the plants for a brief time. Eventually, the biochar will affect a nutrient gain, once the binding evens out).

Charging Your Biochar Before Planting

Aim for up to a one-inch layer of biochar, mixed to a depth of a minimum of six inches to urge it to the basis zone. you simply got to add it once, because it’ll last for a lifetime or more!

To activate your biochar, the well-liked method is to combine it into your compost heap as you build it. you’ll add the maximum amount biochar as you’ll need for your whole garden, up to a maximum of an equal ratio with the compost.

Not only does this improve the consequences of the biochar when it’s added to your soil, but it also improves the composting process itself – leading to a shorter composting time, stimulated microbial activity, reduced gaseous emissions, and reduced odor.

If you employ soiled livestock bedding in your compost piles, you’ll “double-charge” biochar by spreading it up to an in. thick within the fresh bedding. By the time it’s spent, collected, composted, and prepared to spread on your garden soil, it’ll be activated.

Other effective thanks to activating biochar is to incorporate it when brewing your own compost tea. Just stir it into the water before adding the opposite compost tea materials, and brew as per the regular instructions.

Shortcut to Activating Your Biochar

If you do not have the time to activate your biochar by either of those methods, you’ll choose between a couple of shortcuts.

A week or two before once you will use the biochar, mix it with finished compost, organic, worm castings, humates, and/or mycorrhizae.

Incorporate biochar with any of those just before adding them to the soil.

Irrigate, and wait every week or two before planting.

If you select to not activate your biochar, you’ll instead encourage microbes to “move-in” to the biochar’s porous surface by wetting it down before mixing it into the soil. However, albeit you do not do anything to the biochar before incorporating it into your garden, you’ll still see the advantages of increased water retention, microbial activity, organic matter, nutrient retention, and improved soil structure. Taking the few extra steps described here will simply speed up the method.

Try adding some biochar to your soil and grow organic… for Life!
