Abstract

We face major agricultural challenges that remain a threat for global food security. Soil microbes harbor enormous potentials to provide sustainable and economically favorable solutions that could introduce novel approaches to improve agricultural practices and, hence, crop productivity. In this review we give an overview regarding the current state-of-the-art of microbiome research by discussing new technologies and approaches. We also provide insights into fundamental microbiome research that aim to provide a deeper understanding of the dynamics within microbial communities, as well as their interactions with different plant hosts and the environment. We aim to connect all these approaches with potential applications and reflect how we can use microbial communities in modern agricultural systems to realize a more customized and sustainable use of valuable resources (e.g., soil).

Highlights

  • Soil is considered as one of the most diverse habitats on Earth containing billions of bacteria and millions of fungi, as well as larger organisms such as nematodes, ants, or moles (Bardgett and van der Putten, 2014)

  • In this review we present the challenges and latest efforts that have been made in order to advance our understanding of the different dimensions of microbiomes and how it affects plants

  • The generation of microbial communities with customized activities has the potential to serve as a powerful approach to enhance sustainable agricultural production by increasing crop health, through combatting plant diseases and reducing the application of fertilizers
