Notes to broadcasters on mulch

Mulch is any material (such as decaying leaves, compost or grasses) that is spread on the soil or around a plant to enrich or protect the soil. Many different materials can be used for mulching. Farmers use mulch for various purposes: to protect soils from erosion, to add nutrients, to suppress weeds, to preserve soil moisture, or to add organic matter to soils. Used carefully, mulch can provide many of these benefits, often at the same time. There are, however, situations where mulching is not appropriate. In humid areas, for example, moist and warm conditions can encourage the crop to rot, or mould to flourish.

Mulching is a simple and normally inexpensive technique that can be used to improve degraded soils under many conditions. It would be a good topic to consider as part of a program on practical and low-cost farming practices. Find out more about the use of mulching in your broadcast area by talking to agricultural extension workers or NGO staff. Ask them to participate in an interview or show, and ask them to provide technical information. Make sure they explain advantages and disadvantages which are relevant to local farming conditions. If possible, ask farmers to call in with questions or to share experiences.
