Nutrient leaching is a problem not only for the soil but also our water systems. We want to keep nitrogen where it belongs - in the topsoil - and out of our streams, lakes, aquifers, rivers, and oceans where it grows excessive algae, disrupting aquatic ecosystems.

In 2016 for the San Juan study we found a decrease of 13% and 33% of ammonium nitrogen runoff in the biochar and charged biochar plots respectively. Decreasing nutrient runoff saves growers time and money, and helps keep our water systems clean.
