- Biochar stimulates higher temperatures, resulting in more rapid and thorough composting.
- Higher temperatures also kill pathogens and weed seeds.
- Compost odors are reduced.
- Harmful emissions from compost such as methane, nitrous oxide, and ammonia are significantly reduced.
- Fixed-Nitrogen nutrients normally lost as compost leachate and as nitrous oxide emissions are captured and made available to plants.
Benefits to Soil and Plants:
- Co-composted biochar increases the soil’s water holding capacity.
- Soil and plant usage of water becomes more efficient.
- Soil texture is improved: bulk density, friability, water permeability, porosity, and moisture wicking are all significantly improved.
- The population and activity of rhizobacteria that produce plant-growth stimulating exogenous hormones is increased.
- Soil fungal population and activity are increased; soil fungi mediate the availability of phosphorus.
- Free-living nitrogen-fixing bacterial populations and activity are increased. These bacteria produce nitrates, and minimize the need for inputs of nitrogen fertilizer.
- Fertilizer utilization efficiency is increased; if fertilizer is still needed, much less is needed.
Expect rapid and vigorous plant growth with no added fertilizer in the first growing season, and minimal inputs thereafter. Expect reduced need for water.
Instructions for use
Biochar is very adsorptive, and should not be added directly to soil without some sort of pre-treatment to enable it to immediately benefit soil fertility. Do not add dry biochar directly to soil, otherwise it may suppress plant growth and drive out the worm population until it has been assimilated into the soil over the course of several seasons.
The best way to prepare biochar for incorporation into the soil is co-composting. Sending the biochar through a hot aerobic compost process results in many benefits to the compost as well as the biochar. The biochar is not consumed in the composting process; rather, it enhances the composting process while the composting process coats the biochar in a functional coating that imparts the many benefits that biochar is known for.
Here is the recommended procedure:
- Thoroughly wet the biochar in water until all of it is damp.
- Temper with a quart of finished compost to the mixture as a compost starter if possible.
- Add tempered biochar to compostable materials.
- The ideal ratio is 10% biochar, but 5%-30% also work quite well.
- Turn your compost at least weekly.
- Compost the mixture aerobically until the temperatures drop
Once the compost is mature, either to-dress the soil with the compost and cover with mulch, or mix into the top few inches of soil using a cultivator and cover with mulch.
