Beyond Yield

Pro Farm seed treatments and fertilizers aim to proactively support and enhance general plant physiology. With improved plant physiology and stamina, a number of valuable and measurable effects follow.

A complete treatment cycle with Pro Farm products consists of one seed treatment and two to four foliar treatments. These treatments are usually made together with an existing fertilizer program, so no extra sprayings should be required, reducing total cost of input. Depending on crop the typical final yield increase is up to 10-35% (see more details in Crop Solutions).


Only using the second, foliar part of the treatment will have a positive effect. Different crops react differently, for some the seed treatment have a small direct effect on final yield and on other a more significant. 

Germination and roots

When using Pro Farm seed treatment, seed germination rates are improved and roots become longer and more divided. Plant stand increase and reduces re-sowing. For all crops and especially winter crops, a good start is important. 

Following up with foliar treatments, less energy is spent on extracting micronutrients from the soil, there are more available resources to grow longer and better root systems which in turn give the plant better access to water and primary macronutrients.

Stem and leaf

The main reason you apply the fertilizer as a foliar spray is that the plant absorbs the nutrients delivered with Pro Farm's unique delivery method through their leaves. Instead of pulling it out of the soil, transform and transport it up the stem to its final destination, the nutrients are at the right place in the right form - ready to be used with minimum energy consumption by the plant. As with any sprayed agent, there is some runoff. The runoff is coming to good use also in the soil, even though the direct return is limited.

A successful treatment cycle will affect the photosynthesis efficiency. Laboratory studies conducted on soybean suggests up to 40% more efficient photosynthesis and a significant increase in yield. In the field, the effect is sometimes noticed as a slightly reduced biomass on treated fields. The stems get stronger, field tests with oilseed show a 10% stronger stem on treated plants. 

The plant's natural defence mechanisms against pests and disease is improved. Pro Farm is half-way through a three-year study together with Turku University, looking specifically on increased levels of polyphenols in treated plants as a part of the overall immune system of plants.

All put together it presents a plant with higher metabolic activity and better equipped to tackle the impact of abiotic stress, pests and disease.


Throughout the growing season, there are so many threats to a good harvest. Having stronger and more resilient plants by their own accord where the plants are more likely to withstand stresses caused by too much or too little of water, sun and wind. Together with inputs fighting off pests, diseases and competing plants ultimately result in a higher yield. A higher yield is however worthless if you, as a farmer, pay more for input than you get out when selling your crops. At Pro Farm, we understand this and the return on investment is an integral part when analysing field trials. 

In general, with a full treatment cycle, our field trials show up to between 10-35% yield increase in volume. Quality properties such as sugar, protein, vitamin and starch-levels are usually improved.
