Listen to this week’s radio segment on the environmental benefits of no-till farming.
For an in-depth description of no-till farming and of how farmers will need to adopt the practice to meet increased food demands of the future, see this video published by The Economist.
Some Iowa farmers are helping to reduce air pollution – one untilled row of cropland at a time.
This is the Iowa Environmental Focus.
Researchers already knew that no-till farming could improve soil quality and reduce erosion. But a Purdue University study has found that it can reduce harmful gases too.
Compared to chisel-tilled fields, cropland left untilled in the study released 57 percent less nitrous oxide – a gas that stays in the atmosphere for 120 years and contributes to climate change.
The practice can also help save farmers money because it slows the breakdown of costly fertilizers in the soil.
So thank you, no-till farmers – for growing a cleaner, more prosperous Iowa.
