For gardening and agriculture there are numerous homemade inventions that make our lives easier and we can do them in an ecological way without polluting or damaging our environment.

From organic fertilizers to worm composters, there are various homemade inventions that can help us in our tasks. Today we are going to focus on the compost bin with worms.

What does this invention consist of?

For urban and home gardens, it is good to have organic fertilizers without any treatment that does not contaminate our place or our water. A composter is a machine that generates compost through the degradation of organic matter. This compost can be used as fertilizer. There is a type of composting called vermicomposting, which tries to generate compost through the degradation of organic matter resulting from the biological activity of earthworms.

There is a whole internet trade of various species of worms that are more efficient at degrading organic matter and helping to oxygenate the earth. The purchase and sale of these worms for vermicomposting is an activity that is being seen more and more in the world of organic urban gardens.

How the compost bin works

The compost bin whose “raw material” is the worms has dimensions of only 80×40 cm. In this way we can have organic fertilizer without taking up too much space. In addition, we will gain the advantage that we will not waste vegetable waste.

The creator of this compost bin baptized this great invention as “the worm farm” . In this “farm” the worms begin to carry out their feeding process. As a result of the digestion and defecation of the worms, we obtain the liquid humus of the worms that will help us with the fertilization of the automatic irrigation water. In the lower part of the farm are the seedbeds for the next planting, closing the cycle to obtain our fresh vegetables throughout the year without agro-toxics.

How to make our own compost bin

In order to have this wonder in our urban orchard or in our garden, we must drill a 4-inch tube every 15 cm to form steps through which we will introduce the carbon filter and it will remain perforated, in such a way that in the lower part there are several holes for water drainage.

The other container is perforated at its base to contain the worms and will be fixed to the top of the previous container that already has a tube. A hose is inserted through the 4-inch tube to introduce the irrigation water through it. Finally, humus (earth) is introduced into the tube, we sow our seedlings to the taste of each one. The worms are placed in the container with a little soil and a portion of vegetable waste.

So that too much sunlight does not pass through and does not affect the activity of the worms, a small acrylic lid is made to prevent the passage of light. Three holes are made in the lid in which two of them can be planted with tomatoes, beans or any type of plant that needs a certain height.

To finish our compost bin, a water pump is installed in the hose and it is programmed to do watering intervals during the day. Fill the pump container with water, preferably without chlorine, and with liquid earthworm humus.

As you can see, there are homemade and ecological inventions that can help us in our gardens in a sustainable and healthy way, both for the environment and for us. Thanks to earthworms, we can convert unprocessed vegetable waste into good quality natural fertilizer. This fertilizer goes into the water container where it is used to water and fertilize the plants in our garden. Once our plants are ready to harvest, we can replace them with other seedlings to germinate them continuously and have a constant production.
