Field experiments were conducted to determine the effects of micronutrients application on soil properties of sapota (Achras sapota L.) cv. Kalipatti at Kittur Rani Chennamma College of Horticulture, Arabhavi, India, during the year 2015-2016. Zinc and iron sulphates were used for soil and foliar application, whereas the boron in the form of sodium tetraborate (Jai bore) for soil and solu-bore for foliar application were used. The results revealed that foliar application of 0.5% ZnSO₄+ 0.5% FeSO₄ + 0.3% B lead to maximum utilization of N, P and K by the plant which resulted into reduced concentration of (123.50 kg ha^-1), (11.59 kg ha^-1) and (103.50 kg ha^-1) as well as exchangeable micronutrient content boron (1.70 mg/kg) in the soil.
