The selection of an adequate NPK fertiliser depends on the level of nutrients in the soil and the nutritive needs of the plants grown there. Therefore, a proper soil analysis needs to be performed before starting any plant production. "Fertil" recommends the Natura products taking into account requirements of its customers, and in accordance with the needs related to the soil and crops.

"Fertil", the Fertilisers Factory from Backa Palanka, is the first factory in Serbia to produce mineral fertilisers by applying the compaction technology based on the cutting-edge technology in the world for making granules of homogeneous composition using standard mineral components. This technology implies a completely dry procedure, without generation of waste gases and fluids, thus ensuring compliance with the highest environmental standards.

For the reasons stated above, all Natura products are produced and labelled in conformity with Regulation (EC) No. 2003/2003 relating to fertilisers (EC FERTILISER) and the Law on plant nutrition products and soil enhancers of the Republic of Serbia, and they also meet all conditions and requirements for trade in the EU and the Republic of Serbia.

A lower nitrogen content in Natura formulations results from the fact that Natura fertiliser is a basic fertiliser, intended for use in autumn, for basic treatment, or in spring, as early as possible, when higher amounts of nitrogen are not needed. It is far more important to provide phosphorus and potassium, to make them ready for plants and let them penetrate the soil as deep as possible. In this way, we produce a fertiliser that ensures optimum nutrition, lower costs and maximum yield.
