Suitability Evaluation of Soils of the Coastal Plain Sands for Rain - Fed Maize Production in Acid Sands of South - Eastern Nigeria.

AHUKAEMERE C.M.^*, Onweremadu E. U, Akamigbo, F.O.R., Ndukwu, B.

Soils developed on Coastal plain sands have been classified as acidic soils of low CEC and soil fertility. These fragile sandy soils were evaluated for effective and sustainable rain-fed maize production using FAO land suitability classification system. Profile pits were consequently dug in four different soil units – 100m apart: Umuagwo soil unit ...
