Lecture: David Johnson and Regenerative Ag to Solve Climate Change

Wednesday | May 03, 2017 | 7:00 am — 8:00 pm

Grange at Healdsburg SHED | 25 North Street, Healdsburg, CA 95448

Join us at The Healdsburg Shed on May 3, 2017 at 7 PM to learn about Dr. David Johnson’s research and how to reduce atmospheric C02 by joining a soil revolution whose waste products are healthier food, cleaner water and more productive croplands. $10 donation suggested.
David Johnson’s breakthrough research on microbial life in the soil suggests a viable path for agriculturalists to improve their productivity and crop quality while sequestering atmospheric carbon. Studies at the Institute of Sustainable Agricultural Research indicate that increased soil carbon content, with larger fungal populations, promotes improved plant growth, soil water-holding capacity, increased macro- and micro-nutrient availability, reduced system energy requirements and reduced land preparation and cultivation costs. “Soils with higher carbon content and larger fungal populations enable us to double crop production without increasing water,” Johnson reports. “Increasing soil carbon in our desert soils by 1% can quintuple the water storage capacity of that soil. Adopting regenerative agricultural practices that enable soil microbial communities to flourish increases the efficiency at which plants can capture and store atmospheric carbon and reduces the rate at which soils respire this carbon. Field experiments on range and farmland soils demonstrate an increase of 10.7 to 25.5 tons carbon/hectare/year of soil carbon and a concomitant decrease of 39.2 to 93 tons CO 2 /hectare/year of atmospheric carbon dioxide. These carbon capture rates could allow the offset of all anthropogenic carbon emissions on ~22% of the arable land on this planet.”
