Wasteless application of residual logging biomass for obtaining of environmentally friendly plant protection products and soil additives Project leader Agrita Švarta Duration 2023 - 2025 Research focus 3.Studies of the basic resources of the bioeconomy – land, soil, water – to ensure sustainable use and reduce pollution Source of funding National grant Project partners Latvian state Institute of Wood Chemistry Description of project The aim of research To evaluate the impact of low rates of application of environmentally friendly organo-mineral soil amendments, containing inorganic oligomer in various mass ratio (5, 10 or 15% Si), on yield and yield quality of wheat and potatoes under organic farming conditions. The tasks of project: Determination of effectivity of environmentally friendly organo-mineral soil amendments, containing inorganic oligomer in various mass ratio (5, 10 or 15% Si), on crop-forming components of spring and winter wheatInfluence on the yield and yield quality of wheat, potatoes, dill and radish under organic farming conditions Results The obtained results show that the treatment of seed material with environmentally friendly organo-mineral soil amendments, containing inorganic oligomer in various mass ratio (5, 10 or 15% Si) will promote tested plant growth and development.
