The utilization of biomass ash in sustainable agriculture and increasing its fertilizing efficiency by biological agents, potentially sequestering CO, have become important issues for the global economy. The aim of this paper was to investigate the effects of ash from sorghum ( L. Moench) and Jerusalem artichoke ( L.) biomass, a biogas plant digestate, and a extract, acting alone or synergistically, on soil fertility and the development, health and physiological properties of sorghum plants. The results show novel information concerning differences in the composition and impact of ash, depending on its origin, soil properties and sorghum plant development. Sorghum ash was more effective than that from Jerusalem artichoke. Ash used alone and preferably acting synergistically with the digestate and extract greatly increased soil fertility and the growth, biomass yield and health of sorghum plants. These improvements were associated with an increased chlorophyll content in leaves, better gas exchange (photosynthesis, transpiration, stomatal conductance), greater enzyme activity (acid and alkaline phosphatase, RNase, and total dehydrogenase), and a higher biomass energy value. The developed treatments improved environmental conditions by replacing synthetic fertilizers, increasing the sequestration of CO, solving the ash storage problem, reducing the need for pesticides, and enabling a closed circulation of nutrients between plant and soil, maintaining high soil fertility.
将生物质灰分用于可持续农业，并通过生物制剂提高其肥效，从而潜在地固定 CO2，已成为全球经济的重要问题。本文的目的是研究高粱（ L. Moench）和菊芋（ L.）生物质灰分、沼气厂消化物和 提取物单独或协同作用对土壤肥力以及高粱植物生长、健康和生理特性的影响。结果表明，灰分的组成和影响存在差异，这取决于其来源、土壤特性和高粱植物的生长情况。高粱灰分比菊芋灰分更有效。灰分单独使用，最好与消化物和 提取物协同作用，可极大地提高土壤肥力和高粱植物的生长、生物量产量和健康。这些改善与叶片中叶绿素含量的增加、更好的气体交换（光合作用、蒸腾作用、气孔导度）、更高的酶活性（酸性和碱性磷酸酶、RNase 和总脱氢酶）以及更高的生物质能量值有关。所开发的处理方法通过用替代合成肥料、增加 CO2 的固定、解决灰分储存问题、减少农药的使用以及实现植物和土壤之间养分的闭路循环，来改善环境条件，保持高土壤肥力。
