This technology is mainly applied in semi-arid and sub-humid areas on sandy/loamy plains with low soil organic matter content, low soil pH, and with slopes below 5%. Adequate spacing of animals helps to homogenously distribute the manure on the field (see photo): in cattle this is ensured through tying the animals to poles, in sheep and goats a movable fence serving as night enclosure helps to save labour. Corals and animals are moved to a new spot within the field every 4-5 nights to homogeneously manure fields. Ideal is a rate of 2.5 tons of faecal dry matter per hectare. The application of this amount results in superior grain yields (millet, sorghum) as compared to an unmanured field. High yield response is achieved in the cropping season directly following the corralling (year 1) and in the subsequent two to three years, in which no new deposit of faeces and urine, i.e. no further corralling, is needed. While a 250 kg cow deposits about 1 kg of manure dry matter per night, 7 sheep or 7 goats are needed to produce this same amount. Thus, to cover 1 hectare of land with 2.5 tons of manure, a herd of 15 cattle would need to be corralled during 167 nights; alternatively 178 nights would be needed if 70 small ruminants were corralled. Since individual herds are often smaller than 15 cattle (or 70 small ruminants) and fields are larger than 1 hectare, it is recommended to organize corralling of fields within a community (village) of farmers and especially to revitalize the traditional corralling contracts (‘contrats de parcage’) with transhumant herders.
