The organic fertilizer

By organic fertilizer we mean any fertilizer made up of decomposing organic material. In most cases, manure is used as organic fertilizer, ie the remains of animal manure, left to decompose and ferment for a certain period of time. Manure is also called manure, and is available in small dry pellets, or even of a consistency more similar to a common soil. Despite what one thinks, if the manure is left to ripen correctly it takes on an odor that is not particularly unpleasant. Manure is very rich in mineral salts, especially nitrogen, and can be used as a fertilizer in many situations, both in the garden, in the garden, and in the pots of houseplants. In addition to being a good fertilizer, the manure also contains a good quantity of carbon, which makes it possible to improve the texture and texture of a soil. The addition of manure to the garden soil, for example, helps make it softer and easier to work with.

The compost

In addition to the classic manure, there are other types of organic fertilizer; one of the most used is the compost, which can be found mixed in the classic soils, sold in bags in nurseries, or which can also be produced in the garden. Compost is an excellent soil conditioner, although it does not always contain large amounts of nitrogen or other mineral salts; however, a lot depends on what was used to produce it. The compost practice is the result of the controlled decomposition of vegetable waste, obtained by heaping such waste and leaving it to mature, as it is called in jargon. Special compost bins are also commercially available to produce compost; these are large containers with lids, which help to create a good pile of organic material to be composted, so as to favor their correct decomposition. In order for the compost to be suitable for use in the garden or in the garden, it is necessary to spend some months inside the heap, reaching high temperatures, which reduce the bacterial load and make any seeds present in it sterile. During compost preparation, kitchen waste can also be added to the pile.

The earthworm humus

Among the most used organic fertilizers there is also the earthworm humus. Earthworms are very useful insects for the garden and garden soil because their feeding method allows the soil to be partially digested, and to return a soft and rich soil, perfect for growing plants, in pots and in the open ground . Until a few years ago the earthworm humus was not very easy to find in garden centers, while in the last period the properties are being rediscovered. Compared to other fertilizers it has the practicality of being inexpensive and of being completely respectful of the plants and their root system; it can in fact be used freely as a soil improver, adding a good handful to each vase. By its nature, this organic fertilizer is quite rich in nitrogen, and gives the soil a softer and lighter mixture.

Organic fertilizer: Other types of organic fertilizer

In addition to the more classic organic fertilizers, there are also special types, not always available in any gardening store. However, these are fertilizers obtained from processing waste from the food industry, so their use makes it possible to perfectly recycle what should otherwise be thrown away, making these practices particularly ecological. Among the best known organic fertilizers are the remains of animal slaughter, such as bone meal, rich in calcium and phosphorus; or even the cornunghia, a ground of horns and animal nails, rich in different mineral salts, perfect as a slow release fertilizer. Some organic fertilizers have ancient origins, such as lupine flour, widely used throughout southern Italy as a fertilizer for citrus plants.
