Wood Ash[edit]

Wood ash is the residue powder left after the combustion of wood. It is composed of various minerals and compounds, primarily calcium carbonate, and is often used in gardening and agriculture due to its alkaline properties.

Composition[edit]

Wood ash is primarily composed of calcium carbonate (CaCO_), which makes up about 25% to 45% of its content. Other significant components include:

Trace elements such as iron, manganese, zinc, and copper are also present in smaller quantities.

Uses[edit]

Agriculture[edit]

Wood ash is commonly used as a soil amendment in agriculture. Its high calcium content helps to raise the pH of acidic soils, making it a valuable resource for farmers and gardeners. The potassium content also acts as a fertilizer, promoting plant growth.

Cleaning[edit]

Historically, wood ash has been used as a cleaning agent. Its alkaline nature makes it effective for removing grease and stains. It was often mixed with water to create a paste for cleaning purposes.

Other Uses[edit]

Wood ash can also be used in:

Soap making
Glass production
Metal refining

Environmental Impact[edit]

The disposal of wood ash must be managed carefully to prevent environmental damage. When used appropriately, it can enhance soil quality, but excessive application can lead to soil alkalinity and nutrient imbalances.
