dc.description.abstractStudies in aluminum in two representative acid soils. of Bihar have been made. The soils selected for this purpose are the clay loam sedentary soils of Neterhat and sandy clay loam alluvial soils of Purnea. Both the soils contain illite as a dominant clay mineral. The total Al content of the se soils have been found to vary from 4.20 to 8.95..They bear no relation with the pH of the soils. The water soluble aluminum varies from 0.13 to 1.30 ppm. These quantities also bear no direct relationship with the pH of the soils. On the other hand, the exchangeable aluminum has a definite relationship with soil acidity. As the pH of the soil decreases, the amount of exchangeable aluminum increases. When NH4-acetate (pH 4.8) was used as extracting reagent, the exchangeable aluminum varies from 0.49 to 4.84 m.e. per cent in these soils. NKC1 extraction appeared to bear a more regular relationship in this regard. Though the amount extracted by this extract ant are quantitatively less than the NH4-acetate (pH 4.8). These studies further reveal that the acidity due to A1+++ in the permanent charge in the exchange complex is not of so great a consequence as supposed by many workers in this field.
