Optimizing Plant Growth-Promoting Rhizobacteria to Improve the Relationship Between Above and Below Ground Biodiversity

Abstract

Biodiversity plays a crucial role in ensuring environmental sustainability. Plantrhizosphere microbiome interactions are ecologically important because they can alter the biological, chemical, and physical properties of the soil, ultimately affecting plant productivity. To maintain soil function, bio-ameliorant technologies, new modern composting crop residues, and limited use of synthetic pesticides have all been used to boost microbial activity in the soil. Soil management biotechnology is the use of microbes to maintain soil function, resulting in increased plant productivity. It offers a novel way to deal with a wide range of issues that are currently unsolved by conventional technology. It is thought that an improved relationship between above and below ground biodiversity can contribute to the re-establishment of essential biological functions. The Indonesian Research Institute for Biotechnology and Bioindustry (IRIBB), PT Riset Perkebunan Nusantara, has been working on developing plant growth-promoting rhizobacteria (PGPR) as a bio-ameliorant to improve the relationship between above and below ground biodiversity for sustainable management and increased plant productivity.
