Development of a new technology for production of plant fertilizers from fermentation by-products of biogas production facility – cogeneration residue Project leader Aleksandrs Adamovičs Duration 2019 - 2023 Research focus 4. Development and adaptation of technologies for obtaining high-value agricultural and forest products, as well as in veterinary medicine Source of funding National grant Project partners AS ""JP Ziedi"SIA "Fortum Latvia"SIA "Pampāļi"ZS "Irbenes"LVMI "Silava"SIA "Latvi Dan Agro"ZS LīgoSIA "Dobeles Eko" Description of project The aim of research Developing of new technologies to produce soil fertility improving products (fertilizers) with a high added value from by-products – digests and wood ashes. The tasks of project: 1) Development of production technology of a new type of fertilizer from wood ashes and digestate2) Analysis of different digestate, produced in Latvia, to determine the content of ashes, impact of different mixtures of digestate and wood ashes on plant growth and productivity in vegetation vessels and in field and forest conditions3) development of a technological cycle for production of a competitive product and studying of the impact on the production technology of changes in proportions of raw material4) Creating of new products from by-products of biogas and wood cogeneration stations Results Zuševica, A., Adamovičs, A., Dūmiņš, K., Vendiņa, V., Žīgure S., Lazdina D. (2023). Soil Fertility improvement with mixtures of wood ash and biogas digestates enhances leaf photosynthesis and extends the growth period for deciduous trees. Plants, 12(5): 1152.
