Every year huge amounts of bottom sediments are extracted worldwide, which need to be dis-posed. The recycling of bottom sediments for soil fertilization is in line with the long-promoted circular economy policy and enables the use of micro and macronutrients accumulated in sedi-ments for soil fertilization. When considering potential agricultural reuse of the dredge sediments, the first necessary step should be to analyze whether...

Six treatments including straw biochar and its blends with organic waste (a mixture of anaerobically digested model kitchen waste, stillage and its enhancement with the fish waste digestate, both solid and liquid fractions) were tested via greenhouse experiment using fast-growing and pollution-resilient Miscanthus × giganteus. The four months long tests under spring/summer conditions in northern Poland with six fertiliser loads...

The effect of biochar (Bc) application on marginal soil fertility and growth of Miscanthus × giganteus (M × g) was investigated in a greenhouse-based short-term mesocosm experiment. Straw (SBc) and wood-based (WBc) biochars were added to poor class marginal soil (C = 0.5 %) in 5 volumetric ratios (0, 1, 2.5, 5, 10, 15 % v/v). The composition and nanostructure of SBc and WBc were assessed in reference to European Biochar Certificate...
