In this week’s interview, we talk with Gregg Forster of Wisconsin Mineral Solutions about some of those other nutrients, including the role of calcium as the “truck” that helps move other nutrients in the plant, the role of boron as the “wheels” on the truck, and the role calcium plays in improving soil texture. But like most things in life there can be too much of a good thing, so we also talk about how much calcium is too much. ## Actions - request_transcript: `POST https://stenobird.com/v1/public/podcasts/growing-for-market-podcast-5952314/episodes/beyond-npk-micronutrients-with-macro-impact-with-gregg-forster-of-wisconsin-mineral-solutions/transcription-requests` — Idempotently request low-priority transcript generation for this episode. - read_markdown: `GET https://stenobird.com/podcast/growing-for-market-podcast-5952314/beyond-npk-micronutrients-with-macro-impact-with-gregg-forster-of-wisconsin-mineral-solutions.md` — Read the agent-friendly Markdown representation of this episode resource.
