New fertilizer formulation by Biokasvu now patented and ready for the international market

Biokasvu has succeeded in developing and patenting a fertilizer formulation which stimulates the activity of natural soil micro-organisms so that nutrients are released to be used by crops better than before. With the help of Berggren, this quite novel fertilizer was widely patented in the Western world. The aim for the future is boldly to export the new fertilizer formulation to the international markets.

Biokasvu Oy provides customers with first-class and environmentally friendly products for a variety of uses. The products are made of high-quality renewable and/or recyclable main or side products of industry and agriculture. The history of the small Finnish family enterprise dates back to the early 1980's when the firm was established as a subsidiary of Kemira. Since 1990, Biokasvu has been in private ownership.

The operative activities of Biokasvu are carried out by Tilkanen together with Jaakko Lehtinen, Production Manager. Product development is the responsibility of Tuomas Tilkanen, Project Manager, and Keijo Lehtonen, Ph.D., scientist who has studied microbial life in soil.

NUTRIENTS MADE AVAILABLE FOR CROPS BY STIMULATING MICRO-ORGANISMS

The idea of stimulating soil micro-organisms was first conceived nearly 10 years ago. At that time, Biokasvu tried to solve the common problem of accumulated fibre in golf courses. In Finland and elsewhere, the accumulation of nutrients in the soil over the years had been previously studied, but not the rich activity of living soil micro-organisms in the whole temperate zone.

"Only a few studies indicating that there might be more life in soil than had been previously thought, had been finished by the early 2010's. It was our own experiments that gave us the idea of feeding micro-organisms in the soil and stimulating them to do what they do by nature: to decompose organic matter", Tilkanen recalls.

"Keijo and I started to find out if the decomposition process could be controlled to improve the availability of nutrients to crops."

BERGGREN'S SOLID KNOW-HOW IN THE BIO-SECTOR WAS IMPRESSIVE

On the basis of field experiments made during the research process, the theory could be shown to work in practice. Soon after that, the entrepreneurs had a feeling that this was an invention that should be patented.

"This was all quite a new way of thinking, even to those whose job is to study soil and plant cultivation. Even to them, micro-organisms turned out to be of greater importance than researchers in Finland had previously been able to find out. In view of the entire world, the situation was much the same as in Finland. The activity of micro-organisms and various fungi was and still is slightly mysterious", Tilkanen says.

The first contact with Berggren was about eight years ago when Biokasvu started to draw up a patent application. Berggren and Outi Virtaharju, the contact person for Biokasvu, impressed with their solid know-how in the biotechnological sector.

"Outi was convincing in her views and opinions on how we should proceed with our idea", Tilkanen describes.

PATENTS COVER THE ENTIRE WESTERN WORLD

From the outset, it was obvious that patents would be applied internationally, in the whole Western world. The potential of the invention to replace chemical fertilizers by releasing nutrients from recycled fertilizers to be available for plants in a controlled matter, and to give significant savings of costs, energy and soil, was globally recognized.

"The problems are global, particularly in the temperate climate zone. So the situation is the same everywhere. It is true that patenting involves costs and we are a small firm, but the costs were reasonable in view of their benefits", Tilkanen says.

Up to now, patents have been granted not only in Finland but also elsewhere in Europe and the USA. They cover almost the entire Western world and some parts of Eurasia. The length of the application procedures varied, but now, after a process of about seven years, the applications have reached the finish line. At the moment, a suitable actor is being sought who would be ready to bring this new invention to the international market.

SMOOTH AND EFFICIENT WORK TOWARD A COMMON GOAL

In Tilkanen's own words, collaboration with Berggren was quite smooth and efficient. There were no superfluous meetings, and it was hardly necessary to have physical meetings at all. Conference calls and emails were largely sufficient for communication.

"Outi had the relevant skills and knowledge to advise us which features should be focused on in each patent application. She had a good perspective on the opinions of authorities who grant patents. So Berggren helped us to find the right approach", Tilkanen describes.

"It would have been impossible for us to formulate such patent applications by ourselves. It is true that we have had to work hard, but not once have we needed to bang our heads against a wall but things have gone smoothly", Tilkanen points out.
