Although data regarding the effect of different types of synthetic biochar on plant performance and physical and chemical characteristics of soil is widely available, the effect of natural biochar in this respect is not well known, so far. The purpose of this research was to investigate the effect of 650-million-years old natural biochar at three application levels of 0 %, 2.5 % and 5 % by weight on yield parameters of quinoa plant and the soil water retention characteristic curve in sandy loam, loam, and clay textural classes. The results showed that the application of 5 % natural biochar to the loam soil increased the thousand seed weight by 8 %, but adding 2.5 % of biochar to the sandy loam soil increased biological yield by 2 %, and in loam soil increased root volume by 409 %, compared to the control. The results of the physical parameters of the soil showed that the application of biochar in three soil textures caused an increase in moisture content at the field capacity (1.8 %-11.22 %), a decrease in macropores in the range of 10–46 %, and an increase in micropores in the range of 0.2–10 % in three soil textures. Therefore, it can be concluded that the potential of natural biochar storage affected the physical properties of the soil and increased soil water retention while improving important soil functions.

天然生物炭对不同土壤质地土壤保水能力和藜麦植物生长的影响


尽管有关不同类型的合成生物炭对植物性能和土壤物理和化学特性的影响的数据已广泛获得，但迄今为止，天然生物炭在这方面的影响尚不清楚。本研究的目的是研究具有 6.5 亿年历史的天然生物炭在 0%、2.5% 和 5%（重量比）三种施用水平下对藜麦植物产量参数和沙壤土土壤保水特性曲线的影响。 、壤土和粘土质地类。结果表明，在壤土中添加5%的天然生物炭可使千粒重增加8%，而在沙壤土中添加2.5%的生物炭可使生物产量增加2%，在壤土中根系体积增加8%。与对照相比，409%。土壤物理参数结果表明，在三种土壤质地中施用生物炭导致田间持水量水分含量增加（1.8%-11.22%），大孔隙减少10-46%，三种土壤质地的微孔增加了 0.2-10%。因此，可以得出结论，天然生物炭储存的潜力影响了土壤的物理性质，增加了土壤保水性，同时改善了重要的土壤功能。
