Integrated Soil Fertility Management (ISFM)
approaches

Integrated Soil Fertility Management (ISFM) [埃塞俄比亚]

The Integrated Soil Fertility Management (ISFM) approach has been adopted under the Integrated Soil Fertility Management Project (ISFM+). It was introduced as a quick-win solution to increase both crop and biomass production through the incremental promotion of varied but complementary technology packages.

2. SLM技术的说明

2.1 技术简介

技术定义:

Vermicompost is the product of the decomposition process using various species of earthworms. It is a form of humus and is produced through worms digesting and excreting organic in their casts. Vermicompost has been shown to be an effective organic soil amendment, reducing the need for inorganic fertilizers.

2.2 技术的详细说明

说明:

Vermicomposting is the process by which worms convert organic materials (usually wastes) into a humus-like material known as vermicompost. The process is an aerobic, bio-oxidation, non-thermophilic process of organic decomposition that depends upon earthworms to fragment, mix and promote microbial activity. In making vermicompost, earthworms are very good at transforming dead plant material, and livestock droppings into excellent manure. The excrement of the worms has high nutrient levels and a growth‐promoting effect on plants. Earthworms are very sensitive to changes in moisture and temperature. They need a continuous food supply and protection from ants, birds, and chickens. Compared to ordinary compost making, it needs maximum care. For optimum management practices, vermicompost production must be located close to the homestead where livestock barns are usually located. Livestock droppings (especially those of horses and donkeys) are the best sources of feed in addition to plant biomass and other household refuses. Vermicompost production needs a bin in which the worms live. This holds the bedding and food scraps, regulates the amount of moisture and temperature in the bedding, and blocks light which is harmful to the nocturnal worms. Worm bins can be made from plastic or wooden materials. In Ethiopia, wooden boxes are preferred because they are more absorbent and provide better insulation.
Vermicompost reduces farmers’ investment costs on chemical fertilizers. It also has a sustainable role in restoring soil fertility, ameliorating soil acidity and rehabilitating degraded farmland – all of which are problems in the southwestern part of Ethiopia. In the farm where vermicompost is applied, newly transplanted seedlings, in the case of vegetables, remain green and resilient as the compost improves not only the nutrients but also the moisture content of the soil. According to the land users, annual and perennial crops such as horse beans (Vicia faba), wheat, cabbages and avocados grown under vermicompost do very well. Under ideal conditions, 1,000 earthworms can convert 45kg of wet biomass per week into about 25kg of vermicompost. Therefore, the size of production depends on the number of worms, supply of foods, availability of boxes, and associated management practices. In rows and spot application of vermicompost during planting the crop allows efficient and effective uses of the products.

Currently (2023) the government in the southwestern zones of Oromia Region is promoting vermicompost as a vital organic fertilizer. This signals a change in the public sector's and end-users’ mindset in the use of organic fertilizer as a reliable soil amendment, particularly in acid-prone areas. In general, compost restores soil fertility, increases crop production and improves the livelihood of the end users. While the initial cost of constructing the house and installing bins and worms is high, there is potential for the use of local materials. However, it demands considerable household labour for upkeep.

ISFM+ project of the GIZ covered some minor costs of a farmer.

注释:

Labour cost is estimated for a year, each with half a day for follow-up and care. The establishment price is just an estimation. A farmer can start with a few boxes: a couple or more boxes made of local materials that are less costly. Therefore, the estimation is based on the model farmer's approach since he used corrugated iron sheet roofed house and wooden boxes to establish the vermiculture/ vermicompost production center. Otherwise, locally available materials can be used to build hats and wooden structure with plastic lining to serve as boxes. Once established, the recurrent cost is limited to labor and some pesticides.
