The shape, the growth and the life cycle of the plants are performed only if they receive nutrients from the soil getting everything they need at the right moment of their life cycle. Vegetable species, in order to survive, need substances which are considered fundamental for their existence, and others which are not essential but still complementary for a good development and a healthy growth of the plants. Essential elements called macro elements are phosphorus, potassium and nitrogen. Micro elements are instead iron, zinc, calcium, chlorine, sulphur, and magnesium. Fundamental for plants are also hydrogen, oxygen, carbon, copper, manganese and others. There are also nutritive composites that are utilized only by some species of plants. The majority of these substances are called minerals, because they are inorganic elements existing in nature. Not all the needed minerals can be found in the soil so this is why you will have to provide the soil with these external composites called fertilizers allowing the plant to absorb them through its roots.

Characteristics Fertilizers which are used in nature are generally divided in three main groups: organics (or biologic) chemicals (or minerals) and organic-minerals. Organic fertilizers come from organic substances like manure or animal blood, chemical fertilizers are produced by industrial processes and the organic-minerals come from the mixture of the two. Fertilizers, no matter their origin, can contain some or all the substances needed by the plants. Depending on how many elements they do contain, fertilizers can be identified as complex composites if there are two or more, or essentials, if there is only one.

    Fertilizers Dosage A well management of the usage of fertilizers involves a correct dosage. Chemical fertilizers are bought in packages where the producers indicate the quantity of substances that will have to be added to the soil and the right moment to do so. The right dosage may vary depending on the mixture which composes it, on the kind of plant, on the life cycle stage of the crop, and the kind of fertilizer which will be used. A big factor which conditions the quantity of fertilizer to be added to the soil is the ph of the soil itself. Soils rich in limestone, for example, will not need the presence of calcium. Phosphor becomes useless in soils which are too acid or too basic. A right fertilization process should have the right and balanced amount of essential minerals and micro elements. Usually, composites fertilizers are already balanced while simple fertilizers are needed for those plants which need only a specific element.


    As a general rule, fertilizers are needed to provide a good growth of the plants. Every substance goes to work on specific needs and functions. Too much or not enough of these substances can hurt the plant, so the purpose is to know the correct dosage and practice in order to guarantee the wellness of the crops. Some fertilizers will improve the growth, other will help with the production, others will help the plant in the case of necessity and others will correct some other mistakes deriving from bad maintenance or diseases.
