Naphthenic oil improves artificial fertilisers

The use of fertilisers around the world to boost agricultural production is both vital and constantly under critical scrutiny. Developing products that provide optimum benefits both economically and from an ecological viewpoint is an important challenge for the artificial fertiliser producer. Very small quantities of oil are employed in the production of fertilisers. The market demands optimal products and every link of the chain must be taken into consideration, including the properties of the oil being used.
