The farmers in this story discovered that their soils had become less fertile. Through an ingenious collaboration with a nearby local council, they found materials to turn into compost and restore the fertility of their fields.
There are many methods for making compost, and a variety of resources on the internet that describe these methods. Here is a selection:

The farmers in this story worked together to address the issue of decreasing soil fertility. Are farmers in your broadcast area suffering similar problems? If so, how do they improve their soils? If your soil is less fertile, is the quantity and quality of foods in your local market decreasing?
The scripts offered in these Notes would make an excellent series to present to your listeners on the value of compost as an agricultural fertilizer. Try to involve both farmers and buyers in discussions about how they can work together to solve issues about local soils, and how to improve the fertility of their gardens and fields.
