Building up the organic matter content of coarse-textured soils with organic amendments seeks to ameliorate the productivity of these soils, which is limited by plant available water and nutrient supply. Wood fibre-based sludges from the pulp and pap

Purpose Charred materials are low in bioavailable nitrogen (N) due to gaseous losses and the formation of recalcitrant structures during pyrolysis. Enriching chars with N from wastewaters offers a possibility to upgrade the agronomic value of the cha

Ilmastonmuutoksen myötä sään ääri-ilmiöt yleistyvät. Hyvinä esimerkkeinä äärisäistä ovat heinäkuun 2021 poikkeuksellinen kuivuus sekä kesän 2017 hyvin viileät kasvuolosuhteet. Sateisuuteen ja lämpötilaan liittyvät sään ääri-i
