How to make rational use of Water soluble Fertilizer in Fruit trees

First, a small number of times, which is the most important principle, can meet the characteristics of uninterrupted absorption of nutrients by plants.

Second, it is necessary to achieve nutrient balance, especially drip irrigation. Because in the case of drip irrigation, crops are less dependent on soil and higher on fertilizer.

Third, pay special attention to electrical conductivity. The main reason is to prevent fertilizer from burning leaves and roots, especially when sprinkler irrigation and micro-sprinkler irrigation are used. Because the concentration of fertilizer is too high, the water evaporates, and the leaves burn immediately.

The fourth is to avoid excessive irrigation. Most of the water-soluble fertilizer contains available nitrogen, excessive irrigation, available nitrogen is easy to run away with the water, resulting in waste.

Fifth, it is necessary to understand the application of irrigation facilities and the pH of water, so as to avoid the precipitation of fertilizers and reduce the effectiveness. Especially in saline-alkali soil, it is easy to produce calcium carbonate and so on. You can do an experiment with a small amount of well water to see how much it will precipitate.

Sixth, pay attention to the uniformity of fertilization. (modern fruit industry)
