How often should compound fertilizer be mixed with water to water vegetables (how many days should compound fertilizer be mixed with water to water vegetables)

Fertilizing and watering are two crucial things in the growth process of vegetables.

The frequency of fertilizing and watering is related to the fertilizer used, the variety of vegetables, the growth stage, etc. The amount of watering and fertilization should be adjusted according to the actual situation. Only by scientific fertilization and irrigation can a good harvest be achieved.

Vegetables use different fertilizers and have different fertilization frequencies

There are many types of compound fertilizers, including traditional compound fertilizers and water-soluble fertilizers which are more widely used nowadays. These can all be counted as compound fertilizers.

Due to the different characteristics of water-soluble fertilizers and ordinary compound fertilizers, the amount and frequency of fertilizer application are also different.

Water-soluble fertilizers have higher nutrient content and can be completely soluble in water, so the amount of fertilizer applied is less than traditional compound fertilizers, and the frequency of fertilization is also relatively reduced.

For example, if you use 15-15-15 compound fertilizer for daily irrigation, you will need about 10 kilograms per acre of land, while if you use 20-20-20 water-soluble fertilizer, you only need 5 kilograms per acre.

In recent years, in order to make up for the weakness of compound fertilizer that it takes a long time to take effect, people have soaked compound fertilizer in water before applying it, and achieved good results.

Advantages of using compound fertilizer to soak vegetables

We all know that compound fertilizer is a slow-acting but long-lasting fertilizer. It is usually applied as a base fertilizer, and its effect can last for 90 days. When topdressing is applied, it takes more than 10 days to take effect.

If the compound fertilizer is soaked in water and the nutrients are dissolved in the water, and then used to water the vegetables, they will be quickly absorbed by the roots. The effective period of the fertilizer will be greatly shortened and the effect will be seen in about 3 days.

How to use compound fertilizer and water to water vegetables

Put compound fertilizer in a bucket or basin, pour in clean water, not too much water, just enough to cover the compound fertilizer, stir while pouring water to break up the compound fertilizer particles for easy dissolution. Stir well and soak for half an hour.

Dilution concentration of compound fertilizer with water

Dilute the compound fertilizer with water at a ratio of 1:180, that is, 1 catties of compound fertilizer solution with 180 catties of water, stir evenly and then water the vegetables. The concentration should not be too high during dilution. If the concentration is too high, it will cause excessive fertilizer after being applied to the soil, causing the vegetables to grow wildly. If the concentration is too low, the effect will not be achieved.

How to water vegetables with compound fertilizer and water

Use the root irrigation or trenching method to irrigate. Dig a shallow trench or pit about 5 cm away from the root of the vegetable, pour the compound fertilizer liquid into the trench, and then cover it with fine soil. Note that you cannot irrigate on the leaves and the heart of the vegetable to avoid burning the leaves.

Precautions for watering vegetables with compound fertilizer

Although compound fertilizer has high fertilizer efficiency, its nutrients are relatively fixed, and different soils and different vegetables require different nutrients. Therefore, when we use compound fertilizer to soak vegetables, we first measure the soil to understand what nutrients the field soil needs.

After soaking in water, compound fertilizer should be diluted with water at any time for application. If it is left for too long, the nutrients will evaporate and the fertilizer effect will be greatly reduced.

After watering the vegetables with compound fertilizer liquid, loosen the soil in time to prevent the soil from becoming compacted and affecting root growth.
