Abstract

The rural exodus and immigration contribute to the development of urban agriculture in developing countries. The unsuitable practices of this intensive farming contribute reduce soil fertility. The result is the decline in crop yields and depletion of the resource base. The aim of this study was to assess the gypsum application in acid soil on available aluminum and the combined or not effect of gypsum application and aluminum in soil solution on aluminum, calcium, magnesium and phosphorus in roots and leaves of Hibiscus sabdariffa. A pot experiment was led by calcium as gypsum amendments in different levels. Al concentration in soil solution rapidly decreased significantly below the toxicity threshold value. The gypsum application was a good amendment for Al level decreasing, particularly in roots, and an increase of Ca, Mg and P levels in Hibiscus sabdariffa, exception of Mg in roots and P in leaves. The effect of both gypsum application and Al in soil solution showed a significant decrease of Mg in the roots of Hibiscus sabdariffa.
