Black Chalk with Humic Acids
LIMING + SOIL REGENERATION IN A SINGLE APPLICATION
WHAT IS IT?
Black chalk is an innovative calcium fertilizer that combines high calcium content (CaCO₃) with natural humic acids – organic substances known for their powerful soil-regenerating properties.
This product not only neutralizes acidity but also improves soil structure, microbial activity, and overall fertility.
WHY USE IT?
✅ Raises soil pH – effective, gentle deacidification
✅ Increases humus content and improves soil structure
✅ Activates soil microbiology and enhances nutrient retention
✅ Improves water-holding capacity and nutrient availability
✅ Ideal for soils depleted by intensive farming
✅ 100% natural, organic, and environmentally safe
CHEMICAL COMPOSITION:
➡️ Calcium carbonate CaCO₃: 85–92%
➡️ Humic acids (fulvic & humic) : 5–10%
➡️ Organic matter: 10–15%
➡️ Magnesium oxide MgO: 0,5–1,5%
➡️ Reactivity: > 85%
➡️ Moisture: < 3%
Free from heavy metals, toxins, and chemical pollutants
APPLICATION GUIDELINES:
✅ When: Autumn or spring
✅ Dosage: 0.5–3 t/ha depending on soil pH and condition
