Compositional features of precambrian pegmatites of Ago-Iwoye area South Western, Nigeria

The increase in global demand for rare metal Ta-Nb deposits has caused a resurgence of interest in the search for economically viable deposits. Precambrian pegmatites occurring as near vertical dykes have been studied, with the aim of determining their compositional features and possible economic values. Four thin sections were prepared from the pegmatites of the study area for petrographic study. A total of twenty five...

Evaluation of Sesbania sesban L. (Merr) and Mimosa invisa L. (Fabaceae) as sources of nitrogen in irrigated rice on the Vertisols of the Accra Plains of Ghana

Sesbania sesban L. (Merr) and Mimosa invisa L. (Fabaceae) were grown in rotation with lowland rice (var. KRC Baika). The experiments were conducted on three farmers’ fields at the Kpong Irrigation Project (KIP) sites at Akuse (lat 6° 06' N, long 0° 07' E) and Asutsuare (lat 6° 04' N, long 0° 12' E). In Farm 1, S. sesban and M....
