In this study (first in Turkey), the effect of ammonia fertilization on CO2 production and

activation of dehydrogenase enzyme (DHA) and pH were investigated in comparison to

CULTAN and conventional fertilization methods. The aim of this study was to determine the

microbiological activity (CO2 production, DHA) based on the injection of liquid ammonia

into the soil in comparison to conventionally applied fertilization in the widely spread wheat

cultivation areas of Turkey (Cukurova). According to the results however there were no

statistical significant differences between the applications in terms of CO2 production. The

highest CO2 production was obtained in the %100 CULTAN application (14.36 mgCO2/100

gkt 24 h.) on the injection point and the lowest CO2 production was obtained in the %70

conventional application (13.02 mgCO2/100 gds 24 h.) on the fertilization band. In terms of

DHA the highest values were detected in the %70 CULTAN application (303.5 μg TPF/10

gds) on the injection point and the lowest values were detected in the control plots between the

wheat lines. On the other hand there were no significant results determined between the other

applications. In terms of pH change the lowest pH value was obtained in%70 CULTAN

application by the injection method as 7.71.
