2. Description of the SLM Approach

2.1 Short description of the Approach

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".

2.2 Detailed description of the Approach

Detailed description of the Approach:

An outreach programme aims to educate farmers about the benefits of ploughing rice stubble into the soil, while incorporating green manure crops such as sunn hemp (Crotalaria juncea). It also provides demonstrations on proper and effective SLM techniques that enable farmers to apply this knowledge to improve their own lands. Farmers can generate greater and more sustainable income while reducing production costs. Agricultural staff of the Nakhon Ratchasima Land Development Station coordinate with local government agencies to organize activities and lead campaigns: they also help in planning and group formation. One particular group of 50 farmers is part of a project to encourage the use of organic substances instead of chemicals. A nine-member committee coordinates and drives its activities.
The purpose of group establishment is to exchange knowledge, create networks and develop clusters of active participant farmers to trade experience with SLM in relation to rice growing– including the cultivation of green manures and sunn hemp.
Agricultural academics and officers of the Land Development Department give training, as well as continuous advice, knowledge and support in managing areas with saline soils. The Rice Department provides salt tolerant varieties of rice. Government agencies provide some funding for the approach. They help preparing the learning process for coaching farmers in methods of natural agriculture. Study tours are also organised. Furthermore, a group of volunteer “soil doctors” with knowledge and expertise in the area lend their assistance and collaboration (note that the organisation and activities of soil doctors in Thailand has already been described in WOCAT’s global database). In addition, monitoring is carried out jointly between farmers and officers of Land Development Department.
Between 2010-2011, Land Development Department officials promoted farmers to plant Sunn hemp to plow and cover the soil and create seedbeds to collect seeds for use in the next season, which reduces production costs and increases organic matter in the soil.

  • yes

6.4 Strengths/ advantages of the Approach

Strengths/ advantages/ opportunities in the land user’s view
1. Land users monitor climatic changes in predicting disasters to occur. This is used as data for planning cultivation. As a result, there will be no damage during yield harvesting.
2. Regarding knowledge in managing soil, water and plants for utilization in areas with saline soil, previously, rice farming could be conducted only and there was lack of knowledge of correct and suitable saline soil amendment until currently, costs of production can be reduced.
3. The fact that the wisdom obtained from learning and practices has been applied together with academic principles to restore areas with saline soil which are limitations and obstacles during the past ten years have been eliminated makes farmers utilize areas with saline soil sustainably.
Strengths/ advantages/ opportunities in the compiler’s or other key resource person’s view
Farmers have knowledge and understanding. And accept the technology of saline soil improvement with green manure before planting.

6.5 Weaknesses/ disadvantages of the Approach and ways of overcoming them

Weaknesses/ disadvantages/ risks in the land user’s view How can they be overcome?
Before implementing the technology of planting sunn hemp as a green manure plant, the cultivation area is outside the irrigation zone. This has an effect on biomass of the sunn hemp
The farmers who join the group are ready to learn and observe the surrounding environment, including keeping up with climatic changes all the time. At certain time, there is shortage of labor. There are problems of expensive oil establishing the group is the guideline to solve the mentioned problem.
Weaknesses/ disadvantages/ risks in the compiler’s or other key resource person’s view How can they be overcome?
Climate fluctuations It doesn't rain according to season. Resulting in flooding, drought, which affects the use of green manure biomass
