17. Solving Soil, Water & Yield Problems with Chemistry


Listen Later

In this 17th episode, Bill we sat down with David Seagreen, a chemist, innovator, and one of the minds behind some of the most interesting developments in modern agriculture.

From growing up in a farming community in South Africa to building a fertilizer company in Western Australia, David shares the journey that shaped his thinking around soil, water, and plant nutrition.

We dive into:

  • The real problem with water use in farming
  • Why traditional approaches don’t always work
  • The science behind products like Aquifer and CalBud
  • How nanotechnology and surface area can impact plant growth
  • And how small changes in application can lead to major differences in yield
  • This isn’t theory, it’s decades of hands-on experimentation, problem-solving, and pushing boundaries in agriculture.

    If you’re interested in improving water efficiency, understanding soil behavior, or just thinking differently about farming inputs, this episode is worth your time.
