Compost versus mulch

Compost Versus Mulch

Compost is a form of mulch, but mulch is not necessarily compost. Mulch is any material, organic or inorganic, that is spread over the surface of the soil. Its purpose is to protect the soil from erosion, help retain moisture, moderate soil temperature, and suppress weed growth. Common organic mulches include wood chips, bark, leaves, and straw. Inorganic mulches include gravel, stones, and black plastic.

Compost versus manure

Manure is generally not as good as compost as a fertilizer. Manure is often high in salts, which can damage plants, and it can also harbor harmful bacteria that can contaminate food crops. Compost, on the other hand, is made from decomposed organic matter and is relatively free of harmful pathogens.

Compost versus topsoil

Topsoil is the top layer of soil that is typically found in gardens and yards. It is the layer of soil that is richest in nutrients and organic matter. Compost is a type of topsoil that is made up of decomposed organic matter, such as leaves and grass clippings. Compost is often used as a fertilizer or soil amendment.

Compost versus potting soil

Compost and potting soil are similar in that they are both used to grow plants. However, compost is made from organic matter, such as leaves and grass, while potting soil is made from inorganic materials, such as sand and perlite. Compost is richer in nutrients than potting soil and helps improve the quality of the soil.

Compostable versus biodegradable

Compostable materials are capable of breaking down into compost within a reasonable period of time, in a way that is consistent with the composting process. This means that the compostable material must break down into carbon dioxide, water and biomass, which is the same end result as the composting process.
