Peach tree fertilization should aim to maintain a balance between vegetative growth, flowering, fruit set, and fruit quality. This fruit crop is particularly demanding in nitrogen, phosphorus, and potassium, as well as micronutrients such as calcium and boron, which are essential to prevent physiological disorders and improve post-harvest preservation. A well-planned fertilization program, adapted to soil type and cultivation system, ensures balanced nutrition, soil regeneration, and a sustained production of high-quality fruit.
