In article value of mineral fertilizers is described. Their origin is specified.
Many gardeners and truck farmers have an opinion that all mineral fertilizers are unhealthy. It not so. It is impossible to put in one row pesticides (preparations for pest control and diseases of crops, i.e. synthetic poisons) and mineral fertilizers – a wildlife product.
Under the concept "fertilizer" mineral and organic substances or materials which use for improvement of soils, in a broad sense, are incorporated. And those, and other fertilizers – the main sources of replenishment of nutrients in the soil. Their main difference that is included into composition of organic fertilizers both macro – and microcells, and mineral – is more often any one element, is more rare – two-three. Plus of organic fertilizers that they considerably improve microbiological activity of the soil and its physical properties (rykhyolost) that you will not tell about the majority of mineral fertilizers. But the second (especially nitric fertilizers) have an important property: they are perceived by plants easily and quickly while the organic fertilizers introduced in the soil demand time and good conditions for decomposition. In this regard, mineral fertilizers consider the most acceptable at extra root and summer podkormkax for fast elimination of a lack of a food. It is impossible to consider that production which has been grown up without application of mineral fertilizers, is more nutritious and safe for health.

Therefore the correct solution – not refusal of fertilizers, and their correct use is unique: application in optimum doses, in the necessary terms, taking into account features of the soil.
