Biochar is an organic soil amendment that has deep and complex pores. These pores help to store nutrients, microbes and water.
Use Sunriver High Porosity Biochar for
– improved soil structure & porosity
– creating a better plant root environment
– increases in moisture infiltration & permeability
– improved moisture holding capacity of light soils
– reduced water run off & nutrient leaching
– aiding the proliferation of soil microorganisms
– increased soil pH in acidic soils
The best biochar (biological charcoal) is formed by low temperature pyrolysis, about 500 deg C. This is a high enough temperature to achieve maximal surface area but also low enough temperature to achieve essential bio-oil condensate retention. When used broadly, the term biochar simply refers to charcoal made from any biomass that may, or may not , have a significant bio-oil condensate component. In this broader context biochar is simply, bioavailable carbon that can be used to improve soil quality. Not all biochar is the same.
Proper dispersion is a key component for all biochar applications. A piece of biochar, the size of a sugar cube, has the surface area equivalent to that of a basketball court. When biochar is applied in chunks it has less available surface area then that of finer High Porosity (HP) biochar. Surface area is crucial for storing nutrients, microbes and water. Biochar made from wood pellets or chips, does not have the ability to be easily broken down. Waiting for wood pellets or chunky biochar to increase the available surface area, will take an undesirable amount of time. It’s like comparing a sponge and a rock of the same size (volume), the rock weighs more (greater density) than the sponge, but the sponge has a much greater ability to absorb. HP Biochar has deep and complex pores which help to store nutrients, microbes and water.
Think of Sunriver High Porosity Biochar as an organic sponge for your garden. For best results, get the biochar to the root zone as quickly as possible. For potted plants or raised beds, add 5 – 10% by weight (approx. 1 oz biochar/ lb of soil) & mix thoroughly with your soil. 1 cu ft (7 Gal) covers approx. 50 sq ft of open ground whether lawn, garden or flower beds. Yearly additions, ideally as a fall top dressing, will continue to improve soil quality. Adding Sunriver High Porosity Biochar to your actively aerated compost tea can help kickstart the mycorrhizal fungi for root development.
Sunriver High Porosity Biochar is available in conveniently sized & resealable 1 gal (.16 cu ft) mylar bags, 5 gal (.77 cu ft) plastic buckets & 7 gal (1 cu ft) mylar bags as well as 1 cu yd totes (27 cu ft).

State of Oregon – All products claiming to contain plant nutrients, or intended to induce crop yields or plant growth or to produce any physical, microbial or chemical change in the soil, must be registered with the Oregon Department of Agriculture prior to any distribution, which includes sale, or offer of sale. All agricultural amendment products marketed or distributed in Oregon are required to be registered with the Oregon Department of Agriculture. A product is considered an agricultural amendment in Oregon if it does not contain guaranteed amounts of primary nutrients (nitrogen, phosphorous, potassium), secondary nutrients (calcium, magnesium, sulfur), and/or micronutrients (boron, copper, iron, manganese, molybdenum, zinc), but may induce crop yields or promote plant growth or produce any physical, microbial or chemical changes in the soil
