An outreach programme aims to educate farmers about the benefits of ploughing rice stubble into the soil and incorporating green manure crops such as sunn hemp - as well as other sustainable practices. Groups of farmers are formed, and they are assisted by various organisations including the Land Development Department and volunteer "soil doctors".
Sunn hemp (Crotalaria juncea) has been promoted by the Land Development Department as a green manure plant with the objectives of increasing soil organic matter, improving soil fertility and reducing salinity levels.
