Determination of Some Anions along the Profile of Irrigated Farm Soils

摘要

Concentrations of Phosphates (PO43-), Nitrates (NO3-), Sulphates (SO42-), Chlorides (Cl-), soil pH and organic matter were measured along the profile of irrigated agricultural soils collected in Zaria, a town in Northern Nigeria. The result showed that the irrigated factor, agricultural factor and anthropogenic factor all contributed to the relations between selected chemical properties. The results showed that only chlorides seem to intrinsically relate to the soils.
