Episode 124: Understanding the Complexities of Fruit Trees with Dr. Ted DeJong

Dr. Ted DeJong is a professor at the University of California where he has dedicated approximately 40 years to researching and teaching about stone fruits such as peaches, plums, and nectarines. His primary focus has been understanding the physiology of fruit trees, driven by his desire to probe into how plants function at a fundamental level. One of DeJong's significant contributions is his effort to simplify and clarify the complexities of fruit tree physiology. He’s observed that existing textbooks often describe the functions of trees in great detail but fail to explain how these functions occur. This gap led him to write his book, "Concepts for Understanding Fruit Trees," which distills these complex ideas into more straightforward principles. 

In this episode, Ted and John discuss:

• Maximizing sunlight capture in orchard planting

• Challenges photosynthetic efficiency

• Impact of early ripening fruit varieties on yield

• How the genetic code of tree organs, such as flowers and fruits, dictates their growth and development

• Nitrogen fertilization practices in orchards

• How the day-night temperature cycle influences the activity of different parts of the tree

• The importance of pruning principles and the timing of fruit thinning

About John Kempf John Kempf is the founder of Advancing Eco Agriculture (AEA). A top expert in biological and regenerative farming, John founded AEA in 2006 to help fellow farmers by providing the education, tools, and strategies that will have a global effect on the food supply and those who grow it.

Through intense study and the knowledge gleaned from many industry leaders, John is building a comprehensive systems-based approach to plant nutrition – a system solidly based on the sciences of plant physiology, mineral nutrition, and soil microbiology.

Support For This Show & Helping You Grow Since 2006, AEA has been on a mission to help growers become more resilient, efficient, and profitable with regenerative agriculture. 

AEA works directly with growers to apply its unique line of liquid mineral crop nutrition products and biological inoculants. Informed by cutting-edge plant and soil data-gathering techniques, AEA’s science-based programs empower farm operations to meet the crop quality markers that matter the most.

AEA has created real and lasting change on millions of acres with its products and data-driven services by working hand-in-hand with growers to produce healthier soil, stronger crops, and higher profits.

Beyond working on the ground with growers, AEA leads in regenerative agriculture media and education, producing and distributing the popular and highly-regarded Regenerative Agriculture Podcast, inspiring webinars, and other educational content that serve as go-to resources for growers worldwide.
