“…The second large group is organic fertilizers, which are used for fertilizing willow plantations. Organic fertilizers are rich in organic matter and nutrition and they are sufficient resources for plant growth [34][35][36]. They are readily available from nearby livestock farms, biogas stations, and sewage sludge from wastewater treatment facilities.…”

Willow (Salix) family is one of the fastest-growing woody energy crops. It·has been widely used for biomass energy production in short-rotation plantations, carbon storage in longer rotation, and as a phytoremediation plant in Northern Europe. Willows could be cultivated on a wide range of soils, including marginal land, and they are readily propagated by planting un-rooted cuttings. Soil fertilization is necessary for obtaining a higher biomass yield. Different side products of energy production and municipal waste could be used for soil improvement. The aim of this research is to review fertilization practices in short-rotation willow plantations and their impact on the biomass yield. The data from the literature were collected, and different doses of various fertilizers were compared. The response to fertilization is positive if fertilizer contains complex NPK macro elements. The most appropriate dose per hectare varies depending on the soil properties, soil types, willow varieties, weather conditions, water availability, and other factors. Wood ash and peat could be used for soil improvement to solve the main characteristic marginal soils problems in Latvia – low organic content and pH value. Wood ash has high concentrations of calcium (Ca) and magnesium (Mg) and already is widely used as a liming agent in organic farming. Less demanded peat fractions, dewatered wastewater sludge, and biogas fermentation leftover -digestate contain a high amount of organic matter and nitrogen, therefore, could be used as a replacement for previously used fertilizers such as cattle slurry. In addition, wastewater sludge, digestate, and wood ash are also sources of microelements. A mix of all listed products has a high potential to be used as a complex soil amendment.

“…The biometric parameters of lettuce prove that correction of fertilizer composition by the introduction of micronutrients (LFM) can bring even more benefits: higher chlorophyll content, longer roots, and higher yields than in groups without micronutrients (LF). Therefore, the valorization of digestate may be a promising solution for agriculture, especially in these times of high demand for fertilizers (Keskinen et al 2020 ).…”

This study aims to explore the development of sustainable fertilizers from waste materials of a biogas plant and a brewery. These wastes, rich in organic carbon and nitrogen, were processed with sulfuric(VI) and phosphoric(V) acid mixture, facilitating the production of free amino acids and achieving waste sanitization. This treatment produced by-products, which extended the range of possible applications. The highest concentration of free amino acids (360 mg/l) was achieved through hydrolyzing with a 40% concentration medium over 24 h. In this case, the maximum levels were recorded for beta-alanine (69.3 mg/l), glycine (46.8 mg/l), isoleucine (43.5 mg/l), proline (36.2 mg/l), and valine (31.5 mg/l). The study presents two fertilizer technologies, with and without micronutrients, that satisfy European Parliament Regulation 2019/1009 (Ntot > 2%, Norg > 0.5%, Corg > 3%). Bioavailability of nutrients in the formulations ranged from 60 to 100%. The efficacies of these fertilizers were evaluated in 30-day pot trials with various plant species, with both single application and fertigation tested. Multielement analysis confirmed high nutrient transfer in the soil-plant system, and the inclusion of micronutrients led to biofortification of plant biomass in Cu (48.3 ± 7.2 mg/kg), Mn (249 ± 37 mg/kg), Zn (164 ± 25 mg/kg), and Fe (211 ± 32 mg/kg). These sustainable fertilizers present an alternative to traditional, non-renewable fertilizers and offer promising solutions for precision agriculture and environmentally conscious production.
