Abstract:
This research evaluates how variations in raw input materials affect biochar characteristics, their subsequent performance as soil amendments, and plant growth or development. Utilizing locally available agricultural residues within the Latvian context, two distinct biochar types—derived from hay bales and from low-grade silage—were tested. The study hypothesized that different biochar types uniquely impact wheat yield components and soil agronomical indicators. To test this, a pot trial was conducted on summer wheat across two cropping systems: a conventional system using mineral fertilizers and an organic system using pelletized fertilizer from poultry manure digestate. The results have gradually revealed the contribution of native fertility to ensure minimal production, the influence of applying fertilizer on plant but also on soil to sustain production or not, and the influence of biochar on the soil-plant-fertilizer nexus. Compared to the hay biochar, that from the low-grade silage presented more total nitrogen content and a higher moisture absorption. The high dose of biochar (6 t.ha-1) has highlighted the contrasted effect of both types of biochar on yield whereas their effects on soil parameters and on yield levels when biochar is applied alone were similar.
