Pedogenic Loss and Uptake of Calcium by Gmelina Growing in an Isohyperthermic Kandiudult

E.U. Onweremadu

Abstract:
This study evaluated temporal soil calcium loss within the soil and uptake by plants using Gmelina arborea form 2002 to 2006 at a watershed in Owerri, Southeastern Nigeria Forty pedons were dug and sampled at a regular grid of 400x400 m while 10 Gmelina plants were marked and used for the temporal evaluation of calcium (Ca). Standard analyses were performed on both soil and plant samples. Data obtained were subjected to analysis of variance (ANOVA) and correlation analyses using standard computer software. Results showed significant (p<=0.05) differences in elemental ratios with depth and time. Leaf Ca also varied significantly (p = 0.05) temporally. There were significant positive correlations between soil and plant Ca in 2002 and 2003, non-significance in 2003 while significant negative correlations (p<0.0001) in 2005 and 2006.
