What is Compost?

Compost is a nutrient-rich organic material that is created by the decomposition of plant and animal matter. It is a dark, crumbly substance that can be used to improve soil quality and promote plant growth. 

Here are some of the benefits of using compost:

  • Improves soil quality
  • Promotes plant growth
  • Reduces waste
  • Attracts beneficial insects

After understanding the concept of compost, we will examine two popular types in detail and then compare them to gain a clearer understanding.

Mushroom Compost: Mashroom compost is not made of actual mushrooms, even though it sounds like it. It is actually the leftover parts from growing mushrooms. It is sometimes called mushroom soil because it is used to help other plants grow.

Organic Compost : Organic compost is a type of soil amendment or fertiliser made from organic materials that have undergone decomposition. It is a natural and environmentally-friendly way to enrich the soil and provide essential nutrients to plants.

Now that we have a basic understanding of both types of compost, let's delve deeper into comparing the two.
