Dr. Hatfield is the laboratory director for the USDA\\u2019s National Laboratory for Agriculture and The Environment. He has also served on the faculty of the University of California-Davis and is a Past President of the American Society of Agronomy.

In this short but very powerful episode, Jerry and I discuss the mechanics of improving plant efficiency in capturing water, nutrients, and light and put that into productivity. We talk about the role that the soil-plant continuum plays in not only developing the productivity but also the quality of the products that plant is harvested for. Jerry and I discuss the fundamental functions of the soil aggregate structure and the value of gas exchange and water infiltration.

Episode 10 - Jerry Hatfield - Highlights

3:10 - What have been some of the highlights that have lead Jerry to where he is today?

• What drives Jerry: \\xa0Finding out how can we improve the efficiency of plants to capture water and light, and put that into productivity
• What is the role of all this in increasing productivity and quality of what is harvested

\\xa0

5:30 - Why should we care about soil health?

• What does the surface of the soil look like? (Aggregation structure)
• Getting air and water into the soil helps drive the biological processes under the soil
• This determines what the plants are doing (how well they can take up nutrients)
• We need to care because this makes the whole plant system much more efficient - the soil health is the unifying factor

\\xa0

11:10 - How does soil quality improve so many various characteristics of plants\\xa0

• Creating a more balanced soil - creating a condition for the plant to store more carbohydrates more efficiently, for example
• Allowing the plant to optimize itself

\\xa0

13:00 - How do we regenerate and improve soil health?

• Restoring biological activity - Biology has four needs: food, water, air, and shelter
• Putting a cover over soil
• Allowing the biology to express itself when it\\u2019s not being cooked at high temperatures
• Supplying food to the biological system the entire year
• Diversity of plants increase diversity of biological system

\\xa0

18:30 - How fast can we regenerate and improve soil health?

• We can begin seeing changes within one growing season

\\xa0

20:30 - What has Jerry observed regarding a diverse number of plants producing soil changes?

• Comparing cover crops \\xa0- Cover crop cocktails changes are much more rapid
• Crops begin behaving differently with crop rotation

\\xa0

27:45 - Are we just regenerating soil, or also the thought processes and models around agriculture?

\\xa0

29:00 - Increasing water use efficiency and nutrient efficiency

• Water and nutrients are tied together - optimizing together leads to stability
• The plant may be nutrient limited - leading us to expending water to little effect
• How efficient is the plant at capturing solar radiation?

\\xa0

33:10 - What does Jerry believe to be true about modern agriculture that many others don\\u2019t believe to be true?

• How important improving soils are to increasing productivity - allowing genetics to be optimized

\\xa0

35:20 - What is the opportunity for improved yield and quality? What does this mean for growers in terms of profitability?

• If you improve soils in \\u201cbad\\u201d parts of field, immediately improve overall profitability
• No tillage growers have been able to drop nitrogen by 50% without affecting yields because soil is providing nutrients
• Producers need to think about what they are getting out of their inputs

\\xa0

38:10 - What action should farmers take right now?

• Getting a cover crop on system
• Increasing biology in soil
• Crop rotation and diversity
• Cover crop cocktails
• Reduce tillage
