“…On the contrary, there was a decrease in Fe concentration as seen in Figure 6. Seferoğlu [32] found the Fe concentrations in Ayvalık-type olive in Ayvalık region to be between 55-115 mg kg -1 , and between 60-140 mg kg -1 in Edremit region. Soyergin et al [36] reported the Fe concentration of Gemlik-type olive to be 88-280 mg kg -1 .…”

“…Soyergin [31] reported that Ca concentration was between 1.26-2.94% in Gemlik-type olive. Seferoğlu [32] conducted a study on two different regions and found that leaf Ca concentrations were 1.10-1.80% in Ayvalık region, while 1.00-1.20% in Edremit region. The study of Reuter and Robinson [20] reported the optimum Ca concentrations of olive trees as >%1.0.…”

“…Soyergin [31] reported leaf Mg concentrations of Gemlik-type olive to be 0.12-0.37%. Seferoğlu [32] also worked on Ayvalık-type olive and reported the Mg concentrations changing between 0.15-0.31%. In our study, the Mg concentrations were between 0.15-0.16%, and inside limit values according to [20,33].…”

This research was a one-year study to investigate how increasing rates of humic acid affect the nutrient elements [Nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), manganese (Mn), zinc (Zn) and copper (Cu)] of olive trees (Olea europaea) of 14 years old found in a private cultivation land located in Bozköy of Geyikli, Çanakkale (Latitude 35 S 431667, Longitude 4409876) in 2018. The humic acid used was a suspension of 15% humic and fulvic acid, which was a commercial product (Blackjak SC, pH 4-6). Different concentrations of humic acid [0 (control), 50, 100, 200, 400 mL tree-1] were applied directly to soil of 20-30 cm depth under canopy projection of trees after dissolving in 10 L of water in April. A randomized block design with four replicates and five doses was adopted on 20 trees. 200 leaf samples were taken in December from annual shoot tips as reciprocal leaf couples and nutrient element analyses were carried out. The macronutrient elements N and P significantly increased upon all humic acid applications. However, the changes in the elements K, Ca, Mg, Fe, Zn, and Mn were insignificant in all applications. Humic acid at all concentrations decreased copper in leaves. As a result, addition to routine farmer fertilization, humic acid application at the rate of 50 ml tree-1 was determined to be the sufficient dose for olive trees. Moreover, this mentioned dose is considered to be the most economical dose besides being the most suitable one.
