Once a macadamia orchard is in production, it is extremely important to maintain optimal nutrient levels for the trees. Every year, a large amount of nutrients are taken away from the soil through the fruit. Taking 100kg of fresh fruit as an example, the amount of N, P, K, Ca and Mg taken away are 405g, 37g, 333g, 21.4g, 22.4g respectively (Mike, A .Nagao et al., 1992), and the growth and development of fruit trees also need to absorb nutrients from the soil, therefore, how to apply the optimum type and amount of fertilizer to the macadamia nut plantation is particularly important in orchard management.
