Compost info

Compost is usually composed of organic waste mixed together to form soil. Compost is usually used in gardening.

Most compost’ers usually use a special bin called a composting bin for their compost. Compost is created when various decomposers such as mushrooms, decompose the organic materials.

Compost can be rich in nutrients. It is used in gardens, landscaping, horticulture, and agriculture. The compost itself is beneficial for the land in many ways, including as a soil conditioner, a fertilizer, and as a natural pesticide for soil.



Worms are sometimes used to quicken the decomposing process, this compost, which is the product of worm waste, is called vermicompost.

 At its most essential, the process of composting requires simply piling up waste outdoors and waiting for the materials to break down from anywhere between 6 weeks or more. Modern, methodical composting is a multi-step, closely monitored process with measured inputs of water, air and carbon- and nitrogen-rich materials, but this is not required to create compost..
