- 1. Tech - Transformed Agriculture Jim Chamberlin Happy Dancing Turtle October 9, 2019
- 2. Tech- Transformed Agriculture ● Issues in Agriculture ● Soil Health as a solution ● Appropriate Technology
- 3. Issues in Agriculture Population declines (insects, birds, pollinators) Dead Zones Soil Degradation Animal Welfare Food Quality Who will farm? Credit: Scientific American Credit: Forbes
- 4. Issues In Agriculture - Climate Change Credit: Bruce Haffner
- 5. Agriculture as a Solution
- 6. Soil Health Defined “The continued capacity of soil to function as a vital living ecosystem that sustains plants, animals, and humans.” USDA - Natural Resource Conservation Service The ability to cycle nutrients and water. 85-90% of nutrient cycling is through biology.
- 8. Why Soil Health? ● Synthetic N (30%+) ○ Atmospheric off gassing (N2O) ○ Leaching (groundwater) ● Biologically available N ○ Stable ○ Soil integrity The nitrogen cycle
- 9. The Plant/ Microbe Connection 85-90% of soil fertility is through biology (living organisms) ● Rhizosphere - 1904 - ○ Lorenz Hiltner ○ “Unique population of microorganisms Influenced by the chemicals released from plant roots” ● Symbiosis - mycorrhizea ○ 1934 - Sir Albert Howard ○ P
- 10. Soil Health Principles #1 - Minimize disturbance ○ Tilling / plowing ○ herbicides/ pesticides #2 - Keep soil armoured (plants/ mulch/ residue) ○ Stabilize soil temps ○ Hold moisture ○ Prevent erosion
- 11. Soil Health Principles #3 - Keep living roots in the soil #4 - Increase diversity Minimum four year rotation, Companion Planting, Perennials (agroforestry) Cover Crops (multi-species)
- 12. Soil Health Principles #5 - Integrate livestock “Science has yet to replicate what comes out of the back end of a cow.”
- 13. Appropriate Technology- Soil Testing ● Solvita test - Soil Respiration ● Haney test - ○ Carbon and Nitrogen (C:N ratio) ○ microbial activity (Solvita respiration) ○ Cropping system Credit: Earth Microbiome Project

Editor's Notes
- Land art 4-H, OG mag
- Nitrous oxide occurs in small amounts in the atmosphere, but recently has been found to be a major scavenger of stratospheric ozone, with an impact comparable to that of CFCs. It is estimated that 30% of the N2O in the atmosphere is the result of human activity, chiefly agriculture.[3]
- In 1904 the German agronomist and plant physiologist Lorenz Hiltner first coined the term "rhizosphere" to describe the plant-root interface, a word originating in part from the Greek word "rhiza", meaning root (Hiltner, 1904; Hartmann et al., 2008). Hiltner described the rhizosphere as the area around a plant root that is inhabited by a unique population of microorganisms influenced, he postulated, by the chemicals released from plant roots.
