Effects of soil amendments and drought on zinc husbandry and grain quality in Sahelian sorghum

In developing countries, short supply of Zinc is limiting both crop yield and human health. Improving Zn bio-availability in staple foods would greatly improve public health. It¿s therefore a major challenge to design cereal production techniques resulting in higher Zn mass fractions (MF) in combination with a lower phytic acid (IP-6, the main form of phosphorus accumulation in the grain) MF. In northern Burkina Faso, soil and water conservation (SWC) and soil organic amendments (SOAs) techniques adopted by farmers have improved both water and nutrient availability which consequently increased crop yields. Potentially, this improvement in yield may also improve the bio-availability of Zn from staple foods. This research investigated possible modifications of SOAs as currently practiced by farmers, which increase both the quality and the yield of sorghum in the Sahel
