A RESEARCH PROJECT SUBMITTED TO THE
DEPARTMENT OF SOIL AND ENVIRONMENT MANAGEMENT FACULTY OF AGRICULTURE AND
NATURAL RESOURCE MANAGEMENT
IN PARTIAL FULFILLMENT OF THE REQUIREMENT
FOR THE AWARD OF BACHELOR OF AGRIC SCIENCE (B. Agric)
ABSTRACT
The
Evaluation of water sources for irrigation evaluated in Ekoli Edda of Ebonyi
state. In doing so, the water samples were collected from 20m tube wells at
Achiogba, Ol0-Ekoli, Iminika, Anyaoji, respectively and it was analyzed for soluble
salts (salinity hazard).Concentration relation to calcium and magnesium, sodium
or alkali hazard and concentration of born and other constituents that may be
toxic or harmful to crops.The result of the chemical analysis of the water
sample shows that the underground water in Ekoli Edda is good for irrigation,
but need little treatment for some factor like Residuum sodium carbonate (RSC)
which is high. The Electrical conductivity (EC), sodium Adsorption Ration (SAR)
and sodium (Na) content of the underground water compares favourably with the
standard for irrigation. Also (Ca,Mg,k,p,No3,B,Fe, So4)
of the underground water compares favourably with the standard for irrigation. Some
of the heavy metal are in levels that require that the water should be diluted before
it can be used for irrigation safely.
