The 'rollivator' is an animal-drawn cultivator developed by CEEMAT (Centre d'études et d'experimentation du machinisme agricole tropical) which enables land to be prepared for sowing immediately after the first rains. The rollivator is suitable for use in clayey or sandy soil, and can plough a three furrow-width in one pass, thus making a considerable saving in time and energy. It was designed to work one hectare to a depth of 8-10 cm in ten hours, using a pair of oxen. One of its main advantages is that it prevents the formation of a thick crust on the soil surface. The draft-powered courter, also developed by CEEMAT, is designed for use during the dry season to break up the soil and allow water to penetrate as soon as the rains begin. The furrows it draws reduce run-off and hence minimize erosion. The rollivator and courter both are designed to be used in the Sudano-Sahelian region; by enabling earlier crop sowing, the prospect of a good harvest can be much improved. In CEEMAT trials there have been improvements of up to 2()% in yield on land which has been worked by the courter. CEEMAT, 73 rue Jean-Frantois Breton 3400 Montpellier, FRANCE
