Abstract
Many studies carried out in Burkina Faso have been focused on soil fertility management, runoff and soil erosion control. Conducted on both a research station and a farm (Saria agricultural research station and Pougyango village, respectively), the present study aimed at assessing the interaction between soil and water conservation measures and the use of organic and mineral nutrient sources. At Saria, such runoff and erosion control techniques as stone bunds and Andropogon gayanus grass strips were coupled to organic or nitrogen mineral fertilisers. At Pougyango, half‐moons and zai pits techniques were used together with organic or N‐mineral fertilisers and mulching. The results showed that stone bunds reduced runoff by 53% against 45% for grass strips. The organic fertiliser source (compost, manure) appeared more efficient in runoff and erosion control than the N‐mineral fertiliser counterpart. Combining compost with stone bunds or grass strips induced an increase of 180% of sorghum grain yield while the same soil conservation measures used jointly with the N fertiliser induced an increase of about 70%. Similarly, the half‐moon with compost or animal manure application generated a greater sorghum yield than when used with the mineral fertiliser and in the control plot. The two studies showed that water conservation without the addition of nutrients does not bring about a significant increase in crop yield, particularly in years when rainfall distribution is good. Combining soil and water conservation techniques with organic nutrient sources improved the chemical characteristics and productivity of the soil.
