II. Understanding composting

Composting is a natural process of decomposing organic matter.

This process is possible thanks to the presence of microorganisms such as bacteria, fungi and invertebrates that break down organic matter into nutrients that enrich the soil.

To start composting, it is important to understand the basic principles of composting.

First of all, it is important to know what can be composted and what should not be.

Compostable materials include fruit and vegetable scraps, leaves, grasses, grass clippings, branches and wood chips.

Materials that should not be composted include dairy products, meats, bones, oils and fats, and products containing chemicals such as pesticides and fertilizers.

There are different types of composters, each with their advantages and disadvantages.


Rotary drum composters, for example, compost quickly and efficiently, but are more expensive.

Pallet composters or compost piles are more affordable, but can be more difficult to manage.

It is important to choose a location for the composter that is well drained, shaded, and accessible for adding materials and removing compost.

The compost should also be balanced in terms of dry and wet matter.

Dry materials include leaves, branches and wood shavings, while wet materials include fruit and vegetable scraps, grass clippings and herbs.

A well-balanced compost contains approximately 50% dry matter and 50% wet matter.

Compost should also be mixed regularly to ensure uniform decomposition.

This also adds air to the compost, which helps microorganisms grow and break down material more quickly.

Finally, it is important to maintain adequate humidity in the compost, which should be around 40-60% humidity.

In summary, to understand composting, it is important to know what can be composted and what should not be.

It is also important to choose the appropriate type of composter, a suitable location and to add materials in a balanced manner.

Compost should be mixed regularly and maintained at adequate humidity to ensure uniform decomposition.

In the next part of this article, we will explain how to start a compost.

V. Tips and advice for composting

Composting is easy, but it takes a little know-how and practice.

Here are some tips and advice to help you improve your composting technique:

Mix the materials: for a healthy and balanced compost, it is important to mix brown materials (such as dead leaves, branches, paper) with green materials (such as food waste and garden waste).

Brown materials are rich in carbon, while green materials are rich in nitrogen.

A balanced mixture of these two types of materials creates compost rich in nutrients.

Avoid non-compostable materials: It is important to avoid putting materials in your compost that are not compostable, such as plastic, glass or metal.

These materials will not decompose in compost and may even harm the quality of the compost.

Keep the compost moist: In order for the microorganisms in the compost to break down organic matter, it is important to keep the compost moist, but not too wet.

You can add water if necessary to keep the compost moist.

Aerate the compost: it is important to aerate the compost regularly to encourage the decomposition of the materials.

You can do this by stirring the compost with a fork or similar tool, or by using a composter that has a built-in aeration feature.


Use a composter: Using a composter is a great way to make composting easier and keep your compost organized.

Compost bins come in a variety of sizes and styles, allowing you to find the one that best suits your space and needs.

Compost all year round: You can compost all year round, even in winter. If you live in a colder climate, you can use an insulated composter to help keep your compost warm and active during the colder months.

Be patient: composting can take several weeks or even months, depending on the conditions and the materials composted.

Be patient and continue to mix and aerate the compost regularly to obtain healthy, nutrient-rich compost.

By following these tips and advice, you can improve your composting technique and create healthy, nutrient-rich compost for your garden.

Composting is an eco-friendly and sustainable practice that can help reduce waste, improve soil quality and promote healthy plant growth.
