With an annual crop cultivation, agricultural land pretty quickly exhausted and lose the substance necessary for normal development and growth of plants. It is therefore necessary to use organic and mineral fertilizer to restore the nutritional properties of soil. Chemical fertilizers usually contain a few highly concentrated nutrients – potassium, phosphorus, magnesium, nitrogen and calcium. Complex and mixed fertilizers are complexes of chemical elements and inorganic substances of different composition – for different types of crops and soils. Apply fertilizer such as in greenhouses and greenhouses, and for outdoors, as well as for Indoor flower, country houses and gardens.

Such fertilizers are easy to use, well assimilated by plants and economically beneficial. The most famous fertilizers: ammonium nitrate, diammofos, nitroammofos, , ammophos, urea and ammonium sulfate combine the best of components and universality, apply as a basic introduction into the soil and its seasonal feeding. Usually fertilizers applied to land in during spring or autumn plowing – so they are not blown away by the wind and a better mix with the soil. Mixing with the soil of substances contained in fertilizer, gradually dissolve in the soil, enriching it and improving the nutritional value. It is extremely important as a fertilizer is their during storage and transportation and good friability. Typically, mineral fertilizers, and feed produced in the form of crystals and beads, and treated with special additives that prevent their caking. Mixed and hard-blended fertilizers produced by mixing several kinds of fertilizers on plants or in industrial environments. When mixing is possible occurrence of chemical reactions that can lead to lower amounts of nutrients, or solubility of the final product, which also must be considered.
