2.1 Short description of the Technology

Definition of the Technology:

Liquid compost is produced by chopping and mixing animal dung and fresh plant matter, including plants with insect-repellent properties, in an aqueous medium. This liquid compost can be used as a substitute for mineral fertilizers and for pest control in crops. It can be used on all types of crops, but is particularly suitable for market gardening.

2.2 Detailed description of the Technology

Description:

Liquid compost is produced by chopping and mixing a blend of animal dung and fresh plant matter, including plants with insect-repellent properties, in an aqueous medium. Liquid compost can be used as a substitute for mineral fertilizers and for pest control in crops. It can be used on all types of crops but is particularly suitable for market gardening. Its application over large areas is problematic since the recommended application rates are high. This technique is therefore recommended for small plots, such as those used for market gardening. Various containers, including 20-litre plastic drums, 200-250-litre barrels, or 700-litre concrete tanks, can be used in making liquid compost.
The various steps involved in preparing liquid compost are as follows:
- fill two-thirds of the container with water
- finely chop the green matter, incorporating any repellent/biocidal plants (false neem, neem, tephrosia, comfrey, wormwood, tansy, chili pepper, etc.)
- gradually fill the remaining one third of the container with two parts of green matter and one part of animal manure
- cover the compost bin with a wooden or metal lid, but do not close tightly
- stir with a stick for five minutes, two days after mixing, then every two days until ready
- the process lasts about three weeks. The product must be sieved before use.
The recommended application rate is one litre of liquid compost per square metre, diluted to 50% strength. In market gardening, liquid compost is applied two weeks after transplanting or three weeks after seedling emergence. This product helps:
- improve soil fertility by enriching it with organic matter and promoting the life of living soil organisms
- protect crops against insect attack
On large plots, the application of liquid compost can be challenging due to the recommended application rate. Raw materials for compost production may be in short supply, and some farmers may find it difficult to obtain sufficient quantities of animal manure. In many cases, farmers opt to sell liquid compost by the litre.

4.1 Technical drawing of the Technology

Technical specifications (related to technical drawing):

2/3 of the container should be filled with water, and the remaining 1/3 with animal manure and green organic matter. The should consist of 1/3 manure and 2/3 green matter, cut into small pieces to facilitate decomposition. After blending, the mixture should be allowed to rest for 2 to 4 days. It is then stirred for 5 minutes every 2 days until the 21st day, then sieved before use.
The container options include a 700 L concrete tank, a 200 L plastic container or a 20 L can.
Regardless of the container used, the same ingredient proportions must be adhered to consistently.

4.2 General information regarding the calculation of inputs and costs

Specify how costs and inputs were calculated:

• per Technology unit

other/ national currency (specify):

Ariary

If relevant, indicate exchange rate from USD to local currency (e.g. 1 USD = 79.9 Brazilian Real): 1 USD =:

4300.0

4.3 Establishment activities

4.4 Costs and inputs needed for establishment

If land user bore less than 100% of costs, indicate who covered the remaining costs:

Each farmer was provided with the necessary equipment (1 watering can, 1 bowl, 1 bucket, etc.) by GIZ ProSoil.

Comments:

The availability of raw materials and containers continues to be a limiting factor for operators in the production of liquid compost. However, they can produce as much liquid compost as the supply of these raw materials and containers permits within a year

4.5 Maintenance/ recurrent activities

4.6 Costs and inputs needed for maintenance/ recurrent activities (per year)

Comments:

The costs mentioned are associated with the production of 800 litres of liquid compost.
The cost of stirring the liquid compost is minimal, as it only requires labour for mixing the preparation for 5 minutes per day.
Kapoaka is a traditional Malagasy unit of measurement, equivalent to 300 ml.
The amount of manure may vary depending on its condition, but in this case, dry manure is used.
