Soil Ecology and Bioaccumulation of Heavy Metals by Calotropis procera (Ait) in Drylands of South Eastern Kenya

Calotropis procera is a wild species that drought-resistant and plays number of economic ecological uses. The important in soil fertility improvement, pollution control by monitoring sulphur dioxide emissions the air suitable indicator exhausted soil. This study was undertaken drylands South Eastern Kenyato evaluate species’ ecology ability to bioaccumulate heavy metalsThe objectives research were determine chemical physical properties for survival C. phytoextraction metals from To understand growth procera, two sites namely farmland natural stand used. In sites, samples collected analysed pH, total N, P, K bulk density. tissues (leaves) harvested analyzed K, OC, Zn, Mn, Cu Fe. One-way ANOVA applied assess significance variations (pH, P K), Plant tissue data (total Fe), provenances spacing variables relation field plots. Pearson simple linear correlation coefficient (r) calculated assessing type relationship between site properties. There no significant differences subplots Correlation analysis showed strong positive spatial (Pearson, P<0.01, rs = 0.734) artificial procera. Further, there (p<0.05) pH as well bioaccumulation both stands However, very 0.966) terms pytoextraction/phytoaccumulation (Zn, Fe) concluded can grow wide range levels has its leafy tissues. recommends use remediator soils contaminated with Fe).
