Female narrator:
Then: Farmers used a mouldboard plough to turn the soil over, making it loose…

Text on screen: loose

…and airy…

Text on screen: airy

…for good root growth. It was a popular farming practice, but made soil less fertile over time.

Text on screen: less fertile over time

Top soil could be washed away by rain or blown away…

Text on screen: soil blown away

…by the wind, creating the perfect conditions for disasters such as the prairie dust bowl of the 1930s.

[A cloud of dust blows across the screen, picture fades to a modern black and white one of a man tending his field.]

Text on screen: stalks

…and roots…

Text on screen: roots

…from last year’s crop on the soil surface. This keeps water,

Text on screen: water

…organic matter, and nutrients…

Text on screen: nutrients the soil and reduces erosion.

Text on screen: reduces erosion

It’s better for crops and the environment.
