İzmir İli Tarım Topraklarının Verimlilik Durumları ile Mikroelement Kapsamlarının Belirlenmesi Haritalanması

This research was carried out to determine the fertility and microelement scopes of agricultural soils İzmir province create a database distribution maps (pin maps) by using geographic information systems technique between 2014-2017. Within scope research, total 502 soil samples, representing areas, were taken from 0-20 cm depth with 2.5 km x grid intervals. In samples taken; texture, pH, EC, lime, organic matter extractable phosphorus, potassium, iron, copper, zinc manganese analyzes performed. Soil analysis results classified according certain criteria deficiency, adequacy or excess levels nutrients determined. After classification parameters, created within GIS produced via Inverse Distance Weighted method. According it found that, 55.18% sandy-loamy, 49.60% mildly alkaline, 42.03% slightly saline, 57.17% non calcareous-slightly calcareous, 55.98% had minimal matter. terms available elements, 28.09% did not have enough in elements 47.21% high 90.84% 96.61% manganese, 44.42% 69.91% medium cooper.
