What is the Difference Between Manure and Compost?

🆚 Go to Comparative Table 🆚

The main difference between manure and compost lies in their composition and the process through which they are created. Here are the key differences:

  • Origin: Manure is typically animal dung and is a byproduct of livestock farming, while compost is a mixture of various components, including plant waste, food waste, and other organic materials.
  • Composition: Manure is digested organic material that has not yet decayed or broken down. Compost, on the other hand, is organic material that has been biologically broken down (decayed) into a relatively stable soil amendment.
  • Process: Compost is created through a process of decomposition, where organic materials are broken down into a soil-like substance. Manure, when well decomposed, can be used as a soil amendment similar to compost.
  • Nutrient Content: Composted manure contains lots of nitrogen and is a good source of other nutrients like phosphorus and potassium. Composted plant material also provides important nutrients to the soil but more slowly.
  • Application: Manure is best used when well decomposed and mixed into the soil, adding nutrients and helping bind sandy soils while increasing drainage in clay soils. Compost can be applied to gardens and landscapes as a soil amendment and is generally considered safer and easier to use for the average homeowner and gardener.

In summary, manure is derived from animal waste and has not yet decayed, while compost is created from decomposed organic materials, including plant and food waste. Both can be used to improve soil health and provide nutrients for plants, but they are created and applied differently.

Comparative Table: Manure vs Compost

The main difference between manure and compost lies in their composition and the process involved in their production. Here is a table comparing the two:

Manure Compost
Manure is primarily digested animal waste that is not yet decayed or broken down. Compost is organic material that has been biologically broken down (decayed) into a relatively stable soil amendment.
Manure is typically animal dung and is a byproduct of livestock farming. Compost is a mixture of various components, including plant waste, food waste, and other organic materials.
Manure can contain pathogens or weed seeds, and its nutrient content varies depending on the type of animal it comes from. Compost does not usually contain pathogens, as the decomposition process can reach high temperatures, which helps kill bacteria.
Manure is often used as an organic fertilizer in agriculture. Compost is also used as a soil amendment and fertilizer, but it is considered a safer and more user-friendly option for home gardeners.

In summary, manure is animal waste that has not yet decayed, while compost is a mixture of decomposed organic materials. Compost is generally considered safer and more versatile for gardening purposes, as it does not usually contain pathogens or weed seeds.
