Compost types

Few things reflect the natural renewal cycle as well as the use of different types of organic compost. Thanks to the production of compost, we can recycle many of our organic waste, also obtaining a natural and ecological product that will help our plants to grow more and better.

Do you want to learn more about the different types of composting? So, join us in this article where you will see a gardening guide on 6 types of compost and their characteristics.

What is compost and what is it for

Compost is an organic and ecological fertilizer for plants that is produced by the degradation of organic waste of different types. In other words, when making compost we transform our waste as vegetable remains from the kitchen, or pruning remains from the garden, into a product whose composition allows the plants to absorb their nutrients through the roots, as they are incorporated into the earth.

Plants, especially those that are grown in pots, deplete the nutrients available to them in the soil or substrate and need an extra contribution that allows them to continue growing healthy. Using homemade compost is a cheaper alternative than buying synthetic fertilizer or chemical compost and, in addition, it is an ecological and sustainable method. Therefore, we can say that the compost serves to provide more nutrients to the plants .

Compost types – list

As a summary, we can say that these are the most used types of organic compost :

  • Common compost: pile, surface, compost and industrial.
  • Vermicompost or worm castings.
  • Bokashi, bocashi compost or Japanese compost.

Common compost and its types

Common compost is understood to be the most common and simple system of making homemade compost . There are different methods in its elaboration, which depend mainly on the way or place in which we stack the organic matter so that it decomposes. When making this type of compost it is important to maintain a correct proportion in the different types of waste, which are usually separated between wet and dry or between rich in carbon or rich in nitrogen. If the compost seems too greasy or has strong odors, it most likely contains too much nitrogen-rich residue. On the other hand, if the mixture is too slow to decompose, it is probably due to an excess of carbon-rich materials. These are the differenttypes of common compost :

Common compost in heap

This is one of the methods most used by people who have large gardens or lands. It consists of stacking alternately layers of dry and wet organic materials directly on the ground. The usual thing is to cover the pile with straw or some other similar material, and add water as needed to maintain adequate levels of humidity and heat. It is also necessary to stir the pile regularly to aerate it.

Common surface compost

This is a method that allows the preparation and application of compost in a single process. In it the organic matter is applied directly on the cultivated land, as is done in the green manure or mulching methods . Thus, as microbial life and insects decompose organic matter, nutrients are filtered directly into the soil, enriching it.

Common compost in boxes or composters

It is one of the methods most used by non-professional gardening or horticultural enthusiasts. Its main advantage lies in its simplicity, since you only have to acquire one of the many models of composters or composters that exist for sale. These are optimized and usually incorporate instructions for use to make compost making easier.

Industrial compost

There is also industrial compost, which requires facilities with pipes that provide oxygen to the pile of organic matter and extract the carbon dioxide produced, thus greatly accelerating the process.

Vermicompost or worm castings

Also called worm humus , vermicompost is one of the ecological fertilizers with the most beneficial effect on plants and soil properties, both in terms of nutrients and beneficial microbial load. In fact, it is especially useful in microorganisms, which associate with the roots of plants and protect them from pathogens such as fungi and bacteria.

The vermicompost is made mainly with red worms from California , appreciated for their great voracity and their ability to consume practically any organic vegetable residue, except those of citrus fruits and products of the garlic and onion family.

To obtain it, you only have to acquire some of these worms and a vermicomposter , which can also be made at home without too many problems. As soon as we begin to provide them with organic matter, our worms will not take long to multiply and generate vermicompost.

Bokashi or Japanese compost

The Bokashi compost or bocashi is a type of compost that originated in Japan, so it is also known as Japanese compost . Rice farmers in this country developed it as a way to use their residues and waste productively for their crops.

Its main advantage over common compost is that the decomposition process is much faster . This is thanks to the addition of a culture of microorganisms that is prepared with water, molasses and yeast. In addition, bokashi also has chicken manure or avicompost among its ingredients, as well as ashes, rice husks and charcoal , although some of these materials are substitutable for others.
