A study of the effect of salinity on an irrigated land was carried out at Kofai,
Ardo-Kola Local Government of Taraba State. The study area was divided
into four (4) units designated as A, B, C and D, each unit was subdivided into
five (5) parts, designated as A1, A2, A3, A4, A5, B1, B2, B3, B4, B5, C1, C2, C3, C4,
C5, D1, D2, D3, D4, and D5, respectively, made up of twenty (20) soil samples
that were collected within the irrigated land for the laboratory analysis of
salinity. The parameters analyzed were pH, Electrical Conductivity (EC),
Magnesium, Sodium, Potassium, Calcium, Hydrogen and Aluminum
concentration. The results of the soil sample analysis shows that the mean
value of pH is 5.99 which indicates that the soil is slightly acidic, the mean
value of electrical conductivity (EC) is 0.76 ds/m, Calcium, Magnesium,
Aluminum and Hydrogen concentration were obtained to be 11.29, 7.89, 7.98
and 16.88 mg/l respectively, while Sodium and Potassium concentration were
obtained to be 0.90 and 0.67 mg/l respectively with Sodium Absorption Ratio
(SAR) of 0.25 mEq/l. From the analysis it indicates that the soil is low in
salinity. Similarly for water sample analysis the pH is 7.7 which indicate that
the water is slightly alkaline, EC is 0.8 ds/m, calcium and magnesium
concentration were 0.48 and 0.35 mg/l, while sodium and potassium were 0.57 and 0.71 mg/l respectively, with Sodium Absorption Ratio (SAR) of 0.89
meq/l, which shows that the water sample were found within the safe limit for
irrigation. It can be recommended that application of good quality water,
choice of salt tolerant crops and gypsum be adopted in the study area.
