“…A positive effect of biochar amendments on cereal yields, especially when combined with nitrogen fertilization, has been reported in multiple studies [35][36][37][38]. Zhu et al [39] also found that biochar amendment to soil could also stimulate the growth of crop root systems, which can also be a factor that, over time, improves the utilization rate of nutrients available in soil.…”

The agricultural application of biocarbons (biochar) derived from different biomass sources in the process of pyrolysis is a promising solution for crop productivity and quality, soil health improvement, and carbon sequestration. In a three-year study, the effects of low doses of biochar (1 t∙ha−1 and 3 t∙ha−1) of different origins on winter wheat grain quantity and quality were tested. Six different biochar types were used: biochar derived from wheat husk (WHB), (2) extracted medical plant biomass biochar (MPB), (3) wood chip biochar (WCB), (4) wood sawdust biochar (SB), (5) biochar made from straw of rye (RSB), and (6) meat and bone biochar (MBMB). Higher doses of biocarbon had a positive effect only on wet gluten content. The use of different types of biochar showed a significant impact on grain parameters; however, the results were different in different years of this study. Among the tested biochars, SB (Saw Dust biochar) showed rather good results for most of the parameters tested (the highest grain yield in 2018, the highest weight of 1000 g in 2019, the lowest wet gluten content and gluten index in 2020, the lowest falling number in 2019, and the highest Zellenys index in 2019). MBMB biochar was one of the highest yielders in 2018, had the highest wet gluten content in 2018, and the highest gluten index in 2019 and 2020; the lowest Zelleny’s sedimentation index in 2019; and one of the lowest in 2020. Those made SB and MBMB the most promising biochars tested in this study.
