Determination and Mapping of the Relationship between Potassium and Ammonium of Calcareous Soils with Different Moisture Content

Abstract

The aim of this study was to determine the conditions of potassium (K+) and the inorganic form of nitrogen (NH4+), and to map their current status using geographic information systems, in calcareous soils with different moisture content. Potassium in the soil is in exchangeable, soluble and non-changeable forms. Because the ions are fixed by the same mechanism, their release might be expected to be somewhat similar so, it has been suggested that NH4+ and K+ ions are fixed in soils. This study was carried out in the field of Horticulture Fruit Research Unit (AR-GE) in Osmanbey Campus at Harran University. Mean concentrations were evaluated which soils were extracted in dry and moisture conditions respectively. The average concentration was determined K+ 362 and NH4+ 98 ppm in dry soil while were K+ 258, NH4+ 50.26 ppm in moisture soil. Ammonium and potassium in soil were detected to be lower concentrations in moisture than dry conditions.

Key words: Ammonium, potassium, CBS, moisture soil, jeostatistic.
