The organic fertilizer is made up of elements of an exclusively natural nature, animals and plants. However, there are also mixed fertilizers on the market, formed by two components that remain exclusively animal and vegetable.
In recent years, in light of the massive use that has been made of chemical fertilizers that have led and lead to considerable damage both to crops and to people's health, the use of organic fertilizers has increased and spread. The use of organic fertilizers, therefore organic, has not yet been extended to an industrial level, in fact, it is mostly used mostly by private individuals who practice organic farming. At the industrial level, for the moment, organic fertilization is combined with chemical fertilization.
The reason why the use of organic fertilizers should be preferred instead of chemical ones is due to the fact that this type of fertilizer performs important organic and nutritional functions. So, through organic fertilizers the soil develops and enriches instead of weakening, as happens in cases where mainly chemical fertilizers are used. Organic fertilizers provide the soil with specific nutrients such as potassium, nitrogen and phosphorus, which make it more productive. Organic fertilizers are particularly suitable at the time of planting of the plants and therefore in the preparation of the soil, precisely because the substances of which they are composed arrive in a much simpler way to the soil than to the plant itself, thus allowing the soil to enrich itself and prepare itself. to accommodate crops. Precisely because the most nutritious part of organic fertilizers impregnates the roots of plants, it is important to use this type of fertilizer just when they are still in the first phase of their life. By favoring the use of organic fertilizers, our plants and vegetables are allowed to grow healthier and give them the strength to be stronger against diseases.
Types of organic fertilizer
The organic type fertilizer can therefore be mainly of two animal and vegetable types. Among the fertilizers of animal origin we can mention the zootechnical liquids and the manure, while as regards the vegetable ones the pomace, the compost and the ash derived from the combustion of the wood. As we have said, there are also mixed-type fertilizers among which we recall the pollina and the compost. However, the manure is a semi-organic compound as it is formed from the industrial processing of zootechnical liquids.
Precisely because of this double value that involves a part of industrial processing both the droppings and the zootechnical liquids are used less and less. Furthermore, the zootechnical liquids are not well absorbed by the plants and risk to pollute, instead the pollen, that is the dried excrements, are not free of polluting agents. When zootechnical liquids are used, just to improve the effectiveness, a part of dried excrement is added which allows the soil to absorb all the chemical elements, such as phosphorus, potassium and calcium, which would risk not being well distributed on the ground and therefore to disperse.
Instead, mature manure is widely used for fertilizing vegetable gardens.
Manure can generally be purchased in packs of different sizes where the most suitable method of its use is specified. Usually the manure is used initially in the first phase of cultivation, that is in primrersa or in autumn. The manure, once mixed with soil and soil, can also be used for our house plants.
Compost is born from the fermentation and their transformation of waste.
The compost can be used as an organic fertilizer, organic vegetable remains or leftovers can be fermented, it is absolutely essential not to add plastic, synthetic materials or for example rubber. To make the action of the compost even more effective and to make its chemical-physical characteristics more balanced, it is important to mix wet remains with more dry and dry leftovers. Along with fermentation waste to make composting easier, it is possible to add chips or powder from pebbles and clay. All the mixture must then be chopped and it will go to give life to a heap to be covered with grass or straw, in this way the compound will be protected from light and the entry of the air will be favored which will contribute together with the bacteria to transform and ferment. the whole. After doing this, about six months will have to pass before the compost can be used. Compost can be used as an organic fertilizer both for potted plants and for the garden or vegetable garden.
Without as organic fertilizer
Also from the waste materials deriving from the pressing of the olives it is possible to obtain organic fertilizer, that is, without it. As well as compost, even in this case, a period of fermentation is required together with natural products of about three months. Once three months have passed, the fertilizer obtained can be used for the garden and the vegetable garden. The use of sanza precisely because of its high percentage of nourishment multiplies the yield of the soil, nourishing it much more than common chemical fertilizers. Sanza, together with other fertilizers of vegetable origin, is particularly suitable for fertilizing potted plants.
