- Production of multifunctional biological products to improve hillyland and infertile soils in Quang Tri province.
- Experimental application on some major crops on hillyland and infertile soil.

Theoretical results: Completed the technological process of producing multifunctional biological products to improve for hillyland and infertile soils. These include five bacterial strains: Bacillus subtilis TiN1, Bacillus megaterium CFB3, Bacillus flexus Ti6; Nitrosomonas winogradski NBRC 14297 and Azotobacter chroococcum NBRC 102613;  two fungal strains such as Penicillium oxalicum N19CL and Trichoderma harzianum N4.1; and one actinobacterial strain as Streptomyces diastatochromogenes CLĐ XK3. 
- Applied results: The technological process for producing multifunctional biological products to improve for to improve for hillyland and infertile soils" will be applied to commercialize and produce multifunctional biological products to improve hilly and infertile soils, thereby applying and replicating the model of using products in the whole Quang Tri province: Hai An commune (Hai Lang district), Trieu An and Trieu Van communes (Trieu Phong district), Gio My commune (Gio Linh district) and Vinh Tu and Vinh Thai communes (Vinh Linh district); widely applied to neighboring provinces and areas serving sustainable organic agriculture.

The novelty of this research lies in the optimization of the submerged fermentation process. This fermentation approach involves the production of a multifunctional biological preparation comprising eight strains of beneficial microorganisms. These microorganisms play a crucial role in enhancing soil quality, increasing agricultural productivity, and mitigating crop diseases.
