Apple Irrigation and Fertilization
(Coastal CA, UC ANR Cost Studies)
Irrigation: During summer months, orchards are irrigated 2 times per week using 3 acre-inches with each irrigation event. This helps promote fruit growth and sizing.
Fertilization: Soil and leaf samples are taken once per year to help guide nutrient management practices. Soils are fertilized with ~125 lb per acre nitrogen per year. Nitrogen is best split into multiple smaller dose applications rather than only one large application. Leaf tissue analysis will indicate whether any tree nutrient deficiencies warrant additional applications, such as calcium, boron, or zinc.
