Specifications

1. Description of the SLM Technology

Definition of the Technology : Making compost by burned rice bran to improve the soil fertility in vegetable home gardens.
Description : Compost is used to improve soil fertility and increase crop production. Vegetable home gardens are generally implemented across the country as part of livelihood activity for food security and other source of household’s income for local people. In the past, local land users only used animal manure for improving crop yield and soil fertility. The amount of animal manure applied was dependent on the potential of each household to collect animal manure. In addition, most agricultural land is sandy with shallow depth and mixed with gravel which is not productive for agriculture. Most of vegetable home gardens are situated along streams or riverbanks near the village whereas arable land availability is an issue. In 2016, the Food Security and Nutrition Market Linkage Project supported by International Fund for Agriculture Development (IFAD) has encouraged local people and provided training on how to prepare and use compost with a view to soil improvement and increased crop yields that subsequently should increase food security. Compost is a simple process where local people can use available materials from their own farm production. Materials for compost production include 10 bags of partly burned rice bran (bran burned up to 50% / 15kg/bag), 200kg of animal manure, 50 litre of water, 15 table spoons of molasses or sugar, 5 table spoons of organic extract. All those materials has to mixed together, then should be putted it in a container which is made of cement or plastic (depth: 0,5 m /width: 1,5 m /length: 2 m). After, the compost material in the concrete tank should be flattened and then covered by a plastic sheet. The decomposing process usually takes between 1-2 weeks before the compost can be applied. Buckets or bags are used to carry the compost from the container to the home gardens where - during the land preparation - it is directly spread out on the vegetable plots by fork. Then, the compost will be mixed with the soil by hoe. Now, the soil is ready for planting. Vegetable cultivation may commence from the end of December to March (2-3 cultivation cycles per year). Most people use water from boreholes for the irrigation of the vegetables. In summary, the advantages of using compost are the improvement of soil fertility by adding more organic matters to the soil, increasing of soil nutrients and activation of the organic decomposition process. These positive effects on soil promote crop growth, and finally ends in increased crop yields. The compost production is not complicated, but it needs to be emphasized that attention should be paid to the cleaning of the storage tank and a careful maintenance of tools including shovels and watering cans to keep the costs as low as possible.

Strengths/ advantages/ opportunities in the compiler’s or other key resource person’s view : Compost can modify the soil's condition making it more fertile.
Strengths/ advantages/ opportunities in the compiler’s or other key resource person’s view : If a large quantity is produced, it can be applied over a more extensive area or be sold to generate household income.
Weaknesses/ disadvantages/ risks in the land user’s view : Compost production has so far only results in small quantities as it was still at the trail phase (2017).
Weaknesses/ disadvantages/ risks in the land user’s view : It is bring benefits in the long term as it is a slow process for the compost to improve the soil/s quality (unlike the chemical fertilizer which have an immediately effective).
Weaknesses/ disadvantages/ risks in the land user’s view : If farmers intend to produce compost for rice paddies, they may need quite a large quantity which requires an intensive input of labour in order to collect sufficient raw material.

How can they be overcome? :
How can they be overcome? : It would be preferable to build cement tanks or a concrete containers that would enable farmers to stock a large quantity for more long term use.
Weaknesses/ disadvantages/ risks in the compiler’s or other key resource person’s view : Local people have not yet fully realized the benefits of using compost because the farmers have never used it before.
How can they be overcome? : The compost production process and its benefits shall be disseminated throughout local communities, including knowledge exchange between those communities that have been using compost and those that have not yet started.
