Soil Science: 🧪 What is 'Flocculation' and How Does Gypsum Work?

Is Gypsum really the "Miracle Cure" for heavy clay soil? Most of the time, the answer is NO. 🚫 In this video, we dig into the science of Calcium Sulfate (Gypsum). Learn why it only works on specific "Salty" soils, the chemical process of "Flocculation," and why it is the perfect secret weapon for curing Blossom End Rot in tomatoes without messing up your soil's pH. . 【Key Takeaways】 1. The Clay-Busting Myth 🧱 • Many gardeners believe Gypsum softens all clay soil. • The Truth: It only works if your clay is compacted due to Sodium (Salt). • The Science (Flocculation): Calcium kicks the Sodium off the clay particles, allowing them to clump together and create air gaps. If your soil isn't salty, Gypsum won't improve the structure! 2. Gypsum vs. Lime 🍋 • Both add Calcium, but they behave differently: • Lime: Raises pH (Makes soil more Alkaline). • Gypsum: pH Neutral. It adds Calcium and Sulfur without changing the pH. • Use Case: Perfect for Blueberries or Tomatoes that need Calcium but already have the perfect pH level. 3. When to Use Gypsum? ✅ • If you have a soil test confirming high Sodium (Salt). • To treat Blossom End Rot (Calcium deficiency) when pH is already 6.5. • To loose heavy soil only if it has a salty crust. 4. How to Apply 👇 • Broadcast 1-2 kg per 10 sq meters and water it in well to dissolve the minerals. ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ #Gypsum #SoilHealth #GardeningScience #ClaySoil #Calcium #BlossomEndRot #Flocculation #GardenMyths #SoilAmendments #OrganicGardening
