This program investigates the science of soil, showing that it is a living, breathing ecosystem and one of the most complex structures known to mankind. It gives us clean air, filters our water, and provides us with our food, forests, and wildlife. Digging a cross section into the ground, Irish researchers discuss the conditions soil needs to thrive and feed the planet, the problems created from compaction, and the crucial role earthworms play in running a healthy farm. The program also looks at research on how the microbiology and nutrients in the soil are impacted by the structure, drainage, and farming practices above the ground. It examines the importance of retaining, protecting, and restoring peat bogs in the battle against climate change.
