2.1 ຄໍາອະທິບາຍສັ້ນຂອງ ເຕັກໂນໂລຢີ

ການກຳໜົດຄວາມໝາຍ ຂອງເຕັກໂນໂລຢີ:

Compost production, and its application in planting pits (zai) by farmers on fields near their homes.

2.2 ການອະທິບາຍ ລາຍລະອຽດ ຂອງເຕັກໂນໂລຢີ

ການພັນລະນາ:

Compost is produced in shallow pits, approximately 20 cm deep and 1.5 m by 3 m wide. During November and December layers of chopped crop residues, animal dung and ash are heaped, as they become available, up to 1.5 m high and watered. The pile is covered with straw and left to heat up and decompose. After around 15-20 days the compost is turned over into a second pile and watered again. This is repeated up to three times - as long as water is available. Compost heaps are usually located close to the homestead. Alternatively, compost can be produced in pits which are up to one metre deep. Organic material is filled to ground level. The pit captures rain water, which makes this method of composting
a valuable option in dry areas.
The compost is either applied immediately to irrigated gardens, or kept in a dry shaded place for the next sorghum seeding. In the latter case one handful of compost is mixed with loose soil in each planting pit (zai). These pits are dug 60 cm by 60 cm apart. Three to four grains of sorghum are planted in each pit. Compost in the pits both conserves water and supplies nutrients. This enables the sorghum plants to establish better, grow faster and reach maturity before the rains finish. As compost is applied locally to the crop, not only is the positive effect maximised, but also the weeds between the pits do not benefit. The water retaining capacity of the compost (absorbing several times its own weight) makes the difference. This is much more important than the additional nutrients, which only become available in subsequent years, and do not anyway completely replace all the nutrients extracted by the crops.
The planting pits also help by harvesting runoff water from the microcatchments between them. Boulgou experiences erratic and variable rainfall with frequent droughts. The poor soils are often crusted and have a low water-retention capacity. Due to a high and increasing population, the land has become exhausted, and fallow periods are no longer sufficient as a consequence. Fertility and yields have declined. Sorghum without compost is more vulnerable to drought and crop failure.
During the dry season, after harvest, fields are grazed by cattle of the nomadic pastoral Peuhl, who also herd the agriculturalists’ livestock. Interestingly, the Peuhl have started to systematically collect the manure for sale, since the increased demand (for composting) has led to doubling of the price. Composting has been applied in Boulgou Province of Burkina Faso since 1988.

ຄວາມຄິດເຫັນ:

Major land use problems (compiler’s opinion): Population increase has led to cultivation of all the available arable land, thus shortening or eliminating fallow periods.
Organic matter in the soil is reduced, the water holding capacity of the soil has diminished and consequently yields have fallen. This has been compounded by the droughts of the 1970s and 1980s. Thirty years ago farmers harvested 800 kg/ha each year, but by the 1980s yields had fallen to merely 400 kg/ha on average.

ຄວາມຄິດເຫັນ:

Editors’ comments: Soil fertility decline is a major problem for much of Africa, and composting provides an opportunity for local mitigation of this. There are many ways of making compost, and this case is a good example of ‘aerobic heap compost’ from Burkina Faso. Here, the compost is concentrated in planting pits, which additionally harvest water.

Machinery/ tools: hoe, knife, digging stick, bucket

Costs relate to production and application of one ton of compost per hectare - which a farmer can make in one year and is the product of one full compost pit. The compost is directly applied to each planting pit: since the pits all in all
constitute only around 10-15% of the field surface, compost is effectively applied at a concentration of 7-10 t/ha. This rate is equal to actual rates applied in small irrigated gardens (<0.1 ha). If compost is produced in deep pits, production is cheaper because there is less work involved.

The modest quantity of compost applied is not enough to replace the nutrients extracted by the crops in the long term	Small amounts of nitrogen and phosphorous fertiliser need to be added and crop rotation practiced.
The short/medium term local benefits are not associated with a positive overall, long-term ecological impact because there is a net transfer of organic matter (manure) to the fields from the surroundings	Improve management of the vegetation outside the cropland, avoiding overgrazing etc to increase manure production.
Needs considerable water and thus also extra labour	Pit composting helps to reduce water requirement in drier areas and at the same time reduces labour input.
