Abstract

The aim of this research work is to assess the level of pH in the soil of irrigated farmlands of Kaduna metropolis using PH meter. It was found that Samples obtained from Nasarawa and Kawo (pH = 5.8) were the lowest pH in the samples analyzed. These were similar to the pH of the control site Rigachikun with pH = 5.8 (acidic). Sample from Kurmin mashi had the highest pH value (pH = 8.5) and is alkaline. This revealed that most of the soils from the irrigation sites were acidic with the exception of samples from Unguwan Dosa and Kurmin mashi. It was also obtained from the ANOVA p = 0.0000 < 0.05 which shows that there is significant differences in the pH of soil across the various sampling sites. The real differences of soil pH was further analyzed by a post-hoc test using the Duncan Multiple range test with samples from Kawo, Nasarawa,Kinkinau and Rigasa were the least soil PH. In the second homogeneous subgroup there is Makera, Malali, Badiko, Barnawa, Kakuri, Kudenda, Danmani, etc. while the highest soil pH fall in the third subgroup which include samples from Uuguwan Dosa and Kurmin Mashi. The absorption and accumulation of heavy metals in plant tissues depend upon soil PH and nutrient availability which in turn increase the mobility of heavy metals. This variation in soil PH is due to excessive usage of fertilizer such as NPK, urea, super pHospHate, manure, pesticides, herbicides and other agro chemicals as well as human activities and the use of waste water in irrigating the soil. As such resulting to an adverse effect on such agricultural areas.
