Abstract
In this study, the effects of fertigation with different pH and EC level on soil physical properties such as aggregate formation (AF), aggregate stability (AS) and available water content (AWC) of soil were investigated. In the study, single crop tomato (Solanum lycopersicum, Anıt F1) was grown under cover for two consecutive years. A total of six fertigation applications (F1: pH 7.2/EC 2.0; F2: pH 7.2/EC 3.5; F3: pH 6.5/EC 2.0; F4: pH 6.5/EC 3.5; F5: pH 5.0/EC 2.0 and F6: pH 5.0/EC 3.5) were created, two different EC levels and three different pH levels. Fertigation applications were applied to the soil in three replications and the study was carried out in 18 plots in total. Based on our results, the effect of fertigation applications on the AF of the soil and the AWC during the year was not significant. On the contrary, the effect of fertigation on AS has occurred at different levels and degrees of importance in terms of the effect between years. Fertigation F5, which has a pH 5.0/EC 2.0 levels, caused a significant increase in the stability of 2-1 mm aggregates.
