A new technique has been developed that improves the drainage of vertisols and unlocks the untapped productivity of these heavy clay soils in high rainfall areas. ILCA (International Livestock Centre for Africa) scientists and their collaborators have redesigned an already low-cost implement to form the broadbeds for the broadbed-and furrow (BBF) technique which has been recognized by researchers as a proven method of draining excess surface water The implement is made from two unmodified, traditional Ethiopian ploughs or mareshas. An earlier design of the BBF tool also used two mareshas but they had to be modified and were fixed in a rectangular configuration. This worked well but farmers complained that it was too difficult to assemble, too heavy to transport and the modified mareshas could not be used for primary cultivation. The new design of the implement is triangular with two unmodified mareshas lashed adjacent to each other on the yoke between the oxen. No nuts or bolts are used and farmers can now use their existing mareshas as dual purpose implements and do not have to invest in any additional equipment. ILCA now believe they have got it right - in experiments in farmers' gelds, the BBF technique increased yields of fava beans by up to 330% and durum wheat by up to 130%.
