Cost Calculators

Application rate is 3  gallons per tree if using fresh water, 3-4 gallons per tree if any salt content in the irrigation water, as AG Biochar will help filter the salt content and create a better physical area of protection when watering.  The price quoted $7.80 is based on the 3 gallons per tree.

*During windy conditions or applied to hard top soil so the AG Biochar can’t be blended in, it is advised for the first few months to cover the AG Biochar with either a covering of compost or other soil to keep it from blowing away while the roots get established. 

You only need to purchase AG Biochar and apply to your soil once. It has been proven to work for decades.
