Researchers at the International Centre for Agricultural Research in the Dry Areas (ICARDA) have succeeded in developing a system of pasture and livestock management that will increase livestock production while rehabilitating land not suitable for cultivation and threatened by degeneration and eventual desertification. The solution involves stimulating the growth of pasture leg-umes by applying modest quantities or phosphorus fertilizer. The phosphorus stimulates the legumes which, in turn, extract nitrogen from the atmosphere. This in turn stimulates the growth of grasses. The result is a much greater supply of both grass and legumes for livestock, even in dry years. Increased vegetation also means the return of more organic material to the soil, thereby repairing the damage cause by years of overgrazing. The scientists at ICARDA have found that legume production increased by as much as three times when phosphorus fertilizer was used. Researchers also discovered that by the trial's fifth season the number of seeds in the soil had increased six-fold. In addition, rain-use efficiency was more than double that in the control plots.
