ASSESSMENT OF MICRONUTRIENTS IN SOILS AND WATER FROM FIELDS IRRIGATED WITH WASTEWATER AROUND GINZO RIVER IN KATSINA

Abstract

ABSTRACT Study to assess the micronutrients concentrations of the soils irrigated with wastewater in the Katsina metropolis was conducted in 2016. The sampling areas were divided into three locations, Kofar Marusa. Kofar Durbi and Kofar Sauri with Ajiwa Dam as control. The three locations get their water from Dana Steel Rolling Mill Katsina and domestic wastewater. 16 soil and 3 water samples were collected from each location. Results of lab analysis showed that the soils of the study area were neutral to slightly alkaline; the textural class of the soils was sandy loam. Nitrogen, phosphorous and potassium were found to be high, calcium was found to be medium to high in all the locations based on Esu (1991) ratings. Magnesium was low in Kofar Marusa, medium at Kofar Durbi and Ajiwa and high at Kofar Sauri, sodium was found to be high, and the CEC was high at the three locations and medium at Ajiwa based on Esu (1991) ratings. The concentration of total manganese, zinc, copper and iron was found to be high in all the locations at 5% significant level. Similarly, the concentrations of available micronutrients were also found to be high at 5% significant level in all locations. Correlation studies were carried out between the total and available micronutrients and pH.
