Science: The magic of soil

The world’s farming soils are deteriorating quickly.

Conventional coffee farming where plants are grown using agrochemicals allowed farmers to reap huge harvests these last 70 years. But these agrochemicals have been at the expense of soil health.

I travel to Honduras to explore a potential solution: organic coffee farming.

Come with me as I show you the organic farming tricks of Don Rufino, one of the region’s leading organic farmers.

He nurtures the soil around his coffee trees using mountain microorganisms, a huge diversity of shade trees, attentive tree pruning, and very funky batches of homemade bug spray.

The results speak for themselves: when I pick up a handful of his soil, it is moist, dense and writhing with life.

Could these cultivation techniques be the answer to the coffee world’s declining soil health?
