Abstract :

The aim of this study was to determine the fertility status of Hakkari-Cukurca soils by means of soil analysis. In this survey study, 25 soil samples representing the region were taken. On the soils, pH, EC, CaCO3, texture and organic matter and available nutrient analyses were done. According to results, it was seen that 32 % of the soil is clayey, 48 % of the soil is clayey-loamy, 12 % of the soil is loamy and 8 % of the soil is sandy-clayey-loamy. All of the soils are slightly alkaline and 56 % of the soil have moderate, 36 of soil have high and 8 %of the soil have moderate to high lime content. While there is no salt at 36 percent of the soil, 64 % of the soil contains little salt. Eight percent of the soil contains very little organic matter, 40 % of the soil contains little, 44% of the soil contains moderate and 8% of the soil contains sufficient organic matter. 28% of the soil is sufficient, 64% of the soil is high and 8% of the soil is very high in terms of nitrogen. If an evaluation was made in terms of available nutrient concentrations, it was seen that 16% of the soil had lower, 56% of the soil had sufficient and 28% of the soil had high P. 52% of the soil contained sufficient, 4% of the soil contained lower amount, 36% of the soil contained high and 8% of the soil contained very high amount K. For available Ca, 48% of the samples is low, 52% of is enough. While 4% of the soils contained very little Mg, 96% of the soil contained little amount of Mg. According to micronutrient results, it was seen that 84% of the soil is poor for Fe, 52% of the soils is poor for Mn, 44% of the soil is poor for Zn and 4% of the soil is poor in terms of Cu.
