The forest calculator shows the forest fertilisation potential of the site and calculates the cost of fertilisation and the carbon sequestration benefit, thus making it easier for the forest owner to assess the fertilisation decision. The user interface of the service utilises public forest resource information.

Yara Finland and Mtech Digital Solutions Oy have developed a calculator that provides an estimate of the fertilization potential of a forest plot. The easy-to-use Forest Calculator provides fertiliser recommendations for the site in exchange for the property identifier and also provides an estimate of the fertilisation costs and calculated carbon sequestration caused by fertilisation.

“Fertilisation is the most profitable individual forest management measure. However, it can be challenging to assess the suitability of forest fertilisation or the right fertiliser for one’s own forest plot. The forest calculator makes it significantly easier for forest owners to make a fertilisation decision,” says Juho Salmi, Product Manager for forest fertilisers at Yara.

“Yara’s calculator shows the most profitable forest fertilisation sites. Forest owners are familiar with the map-based interface, and the calculator is easy to use as a document for planning. As a forest owner myself, I found this project interesting and the solution necessary,” says Mikko Jääskeläinen, Commercial Director at Mtech. Mtech has implemented the user interface of the Forest Calculator.

The forest calculator can be found on Yara’s website at yara.fi/metsa or directly at metsalaskuri.fi. The service can also be used in the My Yara service for Yara’s customers.

The calculator is based on public forest resource information

The forest calculator has been implemented using public forest resource information. The forest resource information is updated to the calculator from time to time, so the measures and changes that have taken place in the forest will be visible with a slight delay.

In calculating the potential of forest fertilisation, the calculator utilises the growth models of reproductive fertilisation, the figures of which are very moderate in the light of current research.

“However, the latest data is not comprehensive enough to be used to update the growth models that are commonly used and cover the whole of Finland,” Salmi says.
