Prototype study of agricultural microbial materials utilizing purified water sludge

Abstract

In this study, the objective was to effectively utilize untreated purified water sludge, which is currently underutilized in resource recycling. To achieve this goal, high-value microorganisms were introduced into the purified water sludge, resulting in the development of stabilized materials. By blending this newly developed material with commercially available soil, a novel agricultural material enriched with various functions was created and incorporated into the base soil. In this paper, as part of a preliminary experiment, an environment conducive to maintaining microorganisms with high cellulose decomposition capabilities within purified water sludge over an extended period was initially established. Subsequently, this was applied as a supplementary high-performance material to farm soil developed by Oishi Bussan, and the effectiveness of the applied functional microorganisms in addressing challenges related to plant growth and consecutive cropping was evaluated.
