Everyone who owns a garden, even a small one, knows how many green "waste" it produces, especially if it is flanked by a small vegetable garden. And they also know how much of the time they would devote to the care of the crops, it must be spent instead to give the ecological islands, or the bins, sacks and bags of cut grass, branches, leaves, and maybe even vegetables or fruits that are too ripe, or eradicated to make way for other crops.
Composting allows us to use these wastes, which become raw materials, to produce a fair amount of excellent humiferous soil; in this way the time spent for the "cleaning" of our garden will be able to reward us, even offering us good fertilizer for our garden and garden.
In fact, the appropriate storage and treatment of branches, leaves, grass, leftover food, fruit and vegetable peels, allows bacteria, microorganisms and small insects to feed on them, to develop and decompose the organic substances present in our waste; after a few months the organic material thus treated will become a mass of microorganisms and nutrients, called compost, similar to the humus that we can find in the undergrowth: a soft, well-aerated and mineral-rich soil, excellent for our crops.
First of all you need to choose the type of composter more suitable for our purposes; therefore it is appropriate to evaluate both the time that we usually dedicate to the greenery of our house, and the quantity of waste that usually our garden produces.
The heap: if our garden is large we will have the possibility of creating a heap for composting, or a small, possibly rectangular, area delimited by a fine-meshed net or a trellis. It is advisable to cover the compost heap with non-woven sheets, or jute, to avoid the direct incidence of the sun's rays, and also to limit the water supply due to the rains.
Composter: this is a bell, often made of plastic, with a top opening, for inserting the material to be composted, and a side opening, or a gate valve, to pick up the ripe compost or to check the composting trend. Some types of composter they are distributed by the municipalities, which also guarantee, to those who use them, a discount on waste disposal rates.
Bins: if the material we want to compost is small, or if we want to carry out composting in a confined space, we can use bins, or boxes, suitably perforated, to allow better ventilation, and equipped with a lid.
In any case, it is a good idea that the composting containers have no bottom, or with the bottom made up of a grate, and that they are placed in contact with the ground: in this way, from the soil of our garden, earthworms and other insects will migrate into the compost. which accelerate their decomposition. They should also be equipped with a lid, so that the rain does not alter the contents. To accelerate the decomposition it is also better to grind the material you want to compost, so that it is more easily digestible by bacteria and insects.
