How should water-soluble fertilizer for fruit trees be used reasonably?
First, apply small amounts multiple times; this is the most important principle, as it can meet the characteristic of plants absorbing nutrients continuously.
Second, nutrient balance must be achieved, especially with drip irrigation. This is because under drip irrigation, crops rely less on the soil and more on fertilizer.
Third, pay special attention to electrical conductivity. The main reason is to prevent fertilizer from burning the leaves and root system, especially when using sprinkler irrigation and micro-sprinkler irrigation. Because if the fertilizer concentration is too high and the water evaporates, the leaves will immediately be burned.
Fourth, avoid excessive irrigation. Most water-soluble fertilizers contain quick-acting nitrogen; excessive irrigation makes it easy for quick-acting nitrogen to be lost with the water, causing waste.
Fifth, understand the application of irrigation facilities and the pH of the water to avoid fertilizer precipitation during application, which reduces effectiveness. This is especially true when applying it on saline-alkali land, where calcium carbonate etc. is easily produced. You can use a small amount of well water to do an experiment and see how much is needed to cause precipitation.
Sixth, pay attention to the uniformity of fertilization. (Modern Fruit Industry)
