How to fertilize tomatoes? What fertilizer is good?

There are many vegetable farmers in my country who grow tomatoes. If you want to make a profit from tomatoes, yield is the key. In the management process, scientific fertilization has a great impact on tomato growth, and the focus is different in different growth stages. Let’s learn how to fertilize tomatoes. What fertilizer is good?

1. Base fertilizer

Before planting tomatoes, sufficient base fertilizer should be applied. It is recommended to use compound microbial fertilizer. This type of fertilizer contains organic matter, humic acid, beneficial biological bacteria and chelated trace elements, which can effectively improve the soil and increase soil permeability.

2. Fertilization during the planting period

When planting and transplanting tomatoes, use liquid microbial agents mixed with water and use it as rooting water to water the roots of the tomatoes to promote root development, increase the survival rate, and reduce the occurrence of soil-borne diseases.

3. Seedling-promoting fertilizer

After the tomatoes have taken root, use fully soluble water-soluble fertilizer to dilute with water for irrigation, flushing or drip irrigation. Apply 2-3 times in a row with an interval of 5-7 days to promote the growth of seedlings.

4. Fruit-enhancing fertilizer

When tomatoes enter the fruit-setting period, use high-potassium water-soluble fertilizer for flushing or drip irrigation. Use it 3-4 times to supplement potassium, calcium and other elements to increase tomato yield and quality.

5. Topdressing in the middle and late stages

For late-maturing tomato varieties, the growth and fruiting period is longer, so special attention should be paid to topdressing in the middle and late stages to prevent premature aging of tomatoes and affect yield.

6. Foliar spraying

During the entire growth cycle, Chinese herbal nutrient solution is used for foliar spraying, mainly during the initial flowering period, peak flowering period, fruit setting period, fruit expansion period and after fruit harvesting to prevent diseases and inhibit insect pests.

7. Pay attention to the application of organic fertilizer

Organic fertilizer should be composted at high temperature to avoid root burn and diseases caused by uncomposted organic fertilizer.

8. Medium and trace elements

In tomato production, in addition to paying attention to the macroelements of nitrogen, phosphorus and potassium, we should also pay attention to supplementing trace elements such as boron, molybdenum, calcium and magnesium to prevent the occurrence of deficiency symptoms.

To sum up, tomato fertilization should be based on its growth stage and should use different types of fertilizers, including organic fertilizers, microbial agents, water-soluble fertilizers and foliar fertilizers. At the same time, attention should be paid to the time and method of fertilization, as well as the supplementation of medium and trace elements.
