Our long-term biochar field experiments were sown this May to faba beans, we're set to explore the effects differently activated biochars combined with either different fertilizer rates or fertilizer types have on yield formation and nutrient uptake of the crops as well as on greenhouse gas emissions and soil nutrient availability. In Helsinki, where two of our longest running experiments are located, was extremely dry month of May, almost zero rain. This, one one end, allows the moisture-retaining effects of biochars to become more clearer, on the other hand, posed some challenges on uneven germination of some of the plants.
Thanks to active team on the fields, led by Samuel Amoah, we have succeeded in collecting hundreds of soil, plant and gas samples that we are exploring further in laboratories. Great job everyone, but especially Karel Bartoš, Kira Eskelinen, Zannatul Ferdous, Cecilia Renvall, Faiza Enam, Jasmi Näsäkkälä, Laura Parvila, Lii Lopp! Looking forward for the harvest!
