John Kempf describes how to manage soil nitrogen and carbon sequestration for abundant microbial communities. With these slides, John provides an in-depth explanation of the roles of water, oxygen, and soluble carbon in soil. John explains how the limiting factor for building biology is soluble carbon, not water as many people believe. You will learn why carbon sequestration is important to crop performance, and which elements are needed to stabilize nitrogen in the soil.

1. MANAGING SOIL NITROGEN AND CARBON SEQUESTRATION
A Webinar Hosted by AEA Featuring John Kempf

2. Healthy Soil Biology
needs three things:

3. Oxygen. Water. Food.

4. Oxygen from Soil
Aeration

5. Powdery dry soil still contains 70%
moisture in adsorbed water tightly
bounded to the soil colloids.

6. Biology can access this
adsorbed water
(roots cannot)

7. The limiting factor to
healthy soil biology:

8. Food. Not water.

9. Food source for biology:
soluble carbon.

10. Many soils no longer
have enough carbon

11. Healthy organic matter does
not equal soluble carbon

12. Build soluble carbon with root
biomass and root exudates

13. Build soil carbon with
really healthy plants

14. And with carbon
sequestration

15. 70% of root exudates,
50% of the root biomass, and
30% of the above ground plant biomass
contribute to increased organic matter

16. Fall nitrogen applications
degrade soluble carbon

17. by oxidizing and releasing it
into the atmosphere as
carbon dioxide

18. Only 20% of applied nitrogen is
used by the crop. Most is leached
away and lost to the environment.

19. Our solution to building
microbial communities

20. Step 1. Build high levels of
soluble carbon with really healthy
crops and photosynthesis

21. Step 2. Apply nitrogen only
as needed when needed

22. Step 3. Stabilize nitrogen with
sulfur, carbon, and molybdenum to
reduce application requirements
