In a previous article, we discussed the core value of magnesium sulfate heptahydrate in aquaculture—it provides magnesium and sulfur for fish and shrimp and plays an important role in aquatic mineral nutrition systems (see link below): https://www.kelewell.de/en/post/magnesium-sulfate-heptahydrate-in-aquaculture-not-just-a-mineral-but-a-key-pillar-for-stable-produc However, if we shift our perspective from “functional minerals” back to “fundamental mineral structure,” we will

I. Forms and Availability of Phosphorus in Soil Soil phosphorus can be categorized into two major classes based on its chemical properties: organic phosphorus and inorganic phosphorus . The vast majority exists in forms not readily available to plants, such as insoluble inorganic phosphates bound to iron, aluminum, and calcium, or as organic phosphorus compounds (e.g., phytates, phospholipids). Plants primarily absorb orthophosphate ions (H₂PO₄⁻ or HPO₄²⁻) from the soil

When a high-quality seaweed extract has been properly selected, the real release of its value often lies in the details of precision application. In our previous article, “ Seaweed Extracts for Agricultural Use: A Comprehensive Guide from Definition to Selection ,” we systematically analyzed the differences in how seaweed extracts are understood and categorized. By now, it should be clear that although products may all be labeled as “seaweed extract,” differences in raw mate

Potassium hydroxide (chemical formula: KOH) is a strong inorganic alkali. Under ambient conditions, a 0.1 mol/L potassium hydroxide solution exhibits strong alkalinity, with a pH typically above 13. KOH appears as a white, uniform granular, powdery, or flake solid and is highly soluble in water, forming strongly alkaline solutions. I. Applications and Industrial Landscape of Potassium Hydroxide (1) Industrial-Grade Potassium Hydroxide: A Pillar of Basic Chemical Industry (App
