Using Biochar Amendment for Better Soil

When used broadly, the term biochar simply refers to charcoal made from any organic matter. Biochar is a type of charcoal that can improve soil quality, not all charcoal is good for this.

Raw biochar can be processed further prior to being added to the garden. Adding it to compost, or soaking it with nutrient rich compost tea, urine, or fish emulsion are commonly used to introduce beneficial organisms and nutrients to the porous biochar.

 

What are the benefits of using biochar in the garden?

 

Optimum Soil Properties

Biochar makes better soil, because it changes soil composition in multiple positive ways. With the charcoal amendment, your soil will have better water handling characteristics. It’s porous structure both drains and retains water better, keeping a more consistent water balance.

Biochar reduces soil acidity, and the raise in soil pH also reduces aluminum toxicity. Your soil will have a higher cation exchange capacity after biochar is added. Cation exchange capacity is a bit of a fancy way of saying that on a molecular level, it can hold onto nutrients better.

 

The Soil Ecosystem

Amended soil enjoys an increased web of fungal life deep inside the soil. Healthy microbes thrive, including arbuscular mycorrhizal fungi, which is a needed soil feature that has a symbiotic relationship with the vascular roots in plants.

In fact, your soil should be teaming with life that interacts with the plants you see above ground. Biochar keeps that web of life healthy for you. The presence of biochar increases the microbial respiration and biomass, meaning you have more microbes and they breathe better. This increase in biomass also means that eroded soil is replaced faster than it would be otherwise.

 

Better Fertilization

The amount of fertilizer required for your trees and plants will decrease because of the biochar content. Most estimates say you’ll need 10% less fertilizer for soil areas that have biochar components.

Because of the chemical and porous nature of biochar, your soil will be able to hold higher levels of available Carbon, Magnesium, Phosphorus, and Potassium. This will reduce leaching of nutrients so your soil stays rich.

 

A Long Lasting Investment

The benefits that come from using biochar are not temporary, in fact your grandchildren will be witness to the benefits to the soil that you amend with biochar today. Your trees and plants will grow healthier for years to come as a result of lasting changes that take place in the soil’s inert properties and its ecosystem.
