Abstract
Adequate information on the effects of irrigation on soil physical and chemical properties is critical as it substantially helps in ensuring environmental sustainability. To achieve this, two farmers plot were investigated at Gidan Arju village based on similarities in farming activities. Two profile pits were dug one for each plot and named IrrP1 and IrrP2 respectively. Soil samples collected from the genetic horizon each pedons. The samples were analysed for their physico-chemical properties. The pedons were sandy loam and sandy clay loam in texture at surface and subsurface horizons respectively. The BD was moderate for both pedons. The soil pH (H2O) ranged between 7.9-10 and was rated alkaline to strongly alkaline. Statistically, there was no significant variation between the two pedons. However, the entire samples were marginal in total porosity, OC, AP and low in EC. Total nitrogen, CEC, exchangeable Na, K, Mg and Ca were rated high. Correlation analysis showed insignificant, but negative relationship of BD with TN (r = -0.562), CEC (r = -0.304) and PBS (r = -0.396). From the results of our study it is recommended that phosphate fertilizer and manure should be supplemented to enhance nutrient status of the soils. Similarly, good quality irrigation water was also recommended to improve the soil pH.
