At the same time, according to the pH of the orchard soil, choose fertilizers with different characteristics. The second is to select the amount of fertilizer: on the basis of soil testing, calculate the amount of fertilizer based on how much nutrient the fruit tree needs. The third is to choose the fertilization method: this is very important in the current orchard production management.
