Understanding soil health through the lens of its microbiome

By analysing large microbiome data sets, IBM Research scientists based at the Science and Technology Facilities Council (STFC) Hartree® Centre are working with established agricultural research centre - Rothamsted Research – to understand how soil microbiomes can shape soil health.

Challenge

The ability to understand the microbiological profile of soil, its biochemical properties and fertility is crucial to address global challenges including food security and climate change. Soils are the most complex biological systems on Earth but understanding their microbiomes in detail requires analysis of huge amounts of data. This is a computationally demanding exercise that needs skills in data analytics to provide real insight. Rothamsted Research needed to speed up their metagenomics data processing capability and identify methods that could provide new insight to help understand soil health.

Approach

The IBM Research team developed highly-parallelised workflows suitable for processing large scale metagenomics datasets on the Hartree Centre’s high performance computing (HPC) systems. Using their expertise in data science, the team devised methods to distribute datasets, ultimately reducing the run time from days to hours. By further developing APIs – application programming interfaces – to mine a range of diverse public databases, the team created a rich, integrated knowledgebase used to develop machine learning models that were capable of offering a detailed picture of biochemical activities across soil samples and their connection with overall soil health.

Benefits

This work provided a HPC-enabled solution to the data processing bottleneck experienced in soil metagenomics. The computational and data analytics capabilities of the Hartree Centre complemented the expertise of Rothamsted Research to create a highly-integrated and effective collaboration, providing novel insights towards the understanding of soil health. These tools - developed as part of the Innovation Return on Research (IROR) programme - can now be applied to processing any microbiome datasets, transferable across a
broad range of industry challenges.
