Özet In this study, the effect of adding potassium humate at different concentrations on growth, nutrient uptake, and, fruit nutritional element contents of almond and walnut was investigated. K‑humate application showed differences in the elemental contents of both fruits. Almond and walnut fruits grown in soil without K‑humate contained 9.97 and 9.40 B, 1440.94 and 742.95 Ca, 12.08 and 7.92 Cu, 53.56 and 22.51 Fe, 2507.82 and 2371.05 K, 1724.49 and 1242.57 Mg, 12.69% and 36.96 Mn, 3556.06 and 5284.40 P and 3241.95 and 4407.65 mg/kg Mg, respectively. In K‑humate-treated soils, B, Ca, Cu, Fe, K, Mg quantities of almonds and walnuts were determined as 15.38 and 16.37, 2883.26 and 1396.58, 14.57 and 10.49, 58.70 and 35.99, 5371.24 and 2623.37, 2775.47 and 3411.06 mg/kg, respectively. pH, electrical conductivity (EC; salt), CaCO3, organic matter, inorganic nitrogen (NH4+NO3-N), P, Ca, Mg, Na, B, Cu, Fe, Zn and Mn contents of K‑humate-treated almond soil were found to be 7.55, 128 µS/cm, 42.1%, 2.94%, 57.7 mg/kg, 34.60 mg/kg, 225 mg/kg, 4712 mg/kg, 142 mg/kg, 11 mg/kg, 0.40 mg/kg, 0.73 mg/kg, 4.29 mg/kg, 1.12 mg/kg and 9.19 mg/kg, respectively. While the Cu content in the control group soil was high, the Cu content in the K‑humate-treated soil was found to be sufficient. The inorganic matter amounts of the soil samples were determined at medium and sufficient levels in almond and walnut soils. It has been observed that the lime content of almond soil is higher than that of walnut soil.
