Resumen
Descripción
The Sudan has almost 17 million ha of cultivated land, and the potentially cultivable area is much larger. The Blue and White Nile rivers have enabled the development of large irrigation schemes. The productivity of these schemes has declined in recent years however. Outside the irrigation schemes, farmers use little fertilizer. Even in the scheme areas, fertilizers are underused. Overall, fertilizer use is at a very low level.
