Use of organic fertilizers

Use of fertilizer in agriculture

Soil fertilization is one of the most important practices in agriculture. It is known that plants need water, carbon dioxide (carbon dioxide), sunlight, minerals such as phosphorus, potassium, nitrogen to grow. The fertilization of the soil is essential for the cultivation of some particularly demanding plants, such as cereals (barley, wheat), vegetables (beets, tomatoes) which need large quantities of minerals to give a rich production. Fertilizers are divided into natural and artificial. Natural fertilizers derive from the decomposition of dead living beings, plants and animals, by decomposers (molds, bacteria), which, not being able to manufacture their own food like plants, feed on transforming the remains of other organisms into substances simpler (mineral salts).

Organic fertilizers

Organic fertilizers are organic fertilizers used in organic farming. They are divided into animal, vegetable and mixed organic fertilizers. In organic agriculture, in order to maintain or increase the fertility of the company, it is not enough to replace chemical fertilizers with natural ones but it is necessary to take into account some guiding criteria such as: applying a valid multi-year rotation program, with the cultivation of legumes or vegetables having a deep root system, and then use organic fertilizers that take into account the legislative indications in this regard. In fact, the laws governing organic farming indicate the protocol to be followed, which must be complied with in its entirety. The protocol, among other things, provides that on the packaging of used fertilizers,

Soil fertilization techniques

The fertilization of the soil is the first step to obtain a luxuriant production, whether it is the flowering of garden or apartment plants, or the production of vegetables and fruit. In ancient times when artificial fertilizers did not exist, in intensive agriculture, some precautions were used. Agricultural rotation, a method used already in the Middle Ages, requires that part of the land be cultivated with legumes, in whose roots there are tubercles. These are formed by the action of bacilli widespread in the agricultural soil. The resulting advantage is that the bacillus, present in the tubercles, uses nitrogen from the air to build protein substances, therefore the plant also grows in soils poor in minerals.

Use of organic fertilizers: Types and use of fertilizers

A fertilizer is that substance which, due to its content in nutritional elements or its physical, chemical and biological characteristics, contributes to the improvement of the fertility of the agricultural soil for a better development of the cultivated plant species. They are divided into mineral, organic, organo-mineral, soil improvers and corrective fertilizers. They can be simple (nitrogen, phosphatic, potassium) or compounds. Fertilizers are water-soluble substances that are dispersed in the water; their indiscriminate use can have significant consequences in the environment. The increase in nitrogen and phosphorus-based fertilizers (nutrient elements) in surface waters (fluvial, marine and lake) leads to the phenomenon of “eutrophication” that is
