@usa.technici: Turn Eggshells into Liquid Calcium for Your Plants The process described is an acid-base reaction where calcium carbonate (CaCO₃) from eggshells reacts with an acid (acetic acid from vinegar or citric acid from lemon). This reaction releases carbon dioxide (visible bubbles) and converts the calcium into a soluble form (calcium acetate or calcium citrate), making it easier for plants to absorb when diluted in water and used as a bioavailable fertilizer. #SmartGardening #NaturalFertilizer #SustainableFarming #CalciumForPlants #EfficientGrowing
