Limestone: Calcium Carbonate (CaCO3) - Uses, Preparation, Properties ...

Properties of Calcium Carbonate - CaCO3, It is a fluffy powder. It decomposes to give carbon dioxide when heated up to 1200K. When it reacts with dilute acid, it liberates carbon dioxide as a by-product. CaCO3+H2SO4 → CaSO4+H2O+CO2, At 1200K, calcium carbonate decomposes to give carbon dioxide and calcium oxide. CaCO3 → CaO + CO2,

Too Much Phosphorus In Soil: How To Correct High Phosphorus Levels

Unfortunately, there are no ways to actively reduce excessive phosphorus in garden soil. In working to moderate phosphorus levels in the garden, it will be imperative that growers avoid the use of fertilizers that contain phosphorus. Avoiding the addition of phosphorus for several growing seasons will help reduce the amount present in the soil.
