Evaluation of soil supplements impact on plant growth factors through trials of vegetable cultivation

Abstract

In this study, prototype production of soil supplements was conducted using Trichoderma isolates, and these supplements were evaluated through Komatsuna germination tests and physicochemical assessments. Furthermore, based on the results of the soil supplement prototypes using the aforementioned Trichoderma isolates, high-performance agricultural substrates were produced. During the prototype production, various conditions were investigated, including fungal concentration in the soil supplements and the mixing ratio with commercial substrates. Additionally, cultivation evaluations were conducted using Komatsuna and tomatoes with the high-performance agricultural substrates, revealing the effectiveness of the soil supplements on plant growth.
