What fertilizer is good for beans?

Time for topdressing beans

The first topdressing can be done after the beans are harvested in July. Generally, urea is applied. After that, fertilizer is applied once every two harvests of young pods. Apply thin fertilizers frequently. In order to increase the yield of beans, water and fertilizer promotion can be carried out one week before each harvest. Flower buds will grow from the side branches. As long as sufficient water and fertilizer are provided and the temperature is suitable, the beans can bloom and set pods continuously.

What fertilizer to use for topdressing beans

From the time the beans grow the first compound leaf to the time they sprout, you can apply fertilizer to promote seedling growth and human manure and urea. Control watering and fertilizing before they set pods. After flowering and setting pods, apply compound fertilizer and human manure and urine heavily to promote the early growth of lateral buds, the development of lateral and main vines, and increase yield.

Should urea or compound fertilizer be used for topdressing beans?

It is better to use compound fertilizer as topdressing for beans. Beans absorb more potassium and less phosphorus, but they still prefer phosphorus fertilizer. Phosphorus and potassium fertilizers should be applied in the base fertilizer. A small amount of lime can be applied to acidic and calcium-deficient soils before sowing.

Method of topdressing beans

It is necessary to apply topdressing at the right time and appropriately according to the fertility of the soil, the growth stage of the beans and the growth of the plants. The amount of topdressing should not be increased arbitrarily. For example, less application should be made in fertile soil and more application should be made in barren soil. Less application should be made in the seedling stage and more application should be made in the flowering and pod stage. Fertilizer should be the main fertilizer in the seedling stage, and organic and inorganic compound fertilizers should be mainly applied in the flowering and fruiting stage.

Precautions for topdressing beans

Beans contain nitrogen-fixing rhizobia, which fix nitrogen themselves. Do not apply excessive nitrogen fertilizer, but do apply it either, otherwise it will be difficult to bear fruit. In addition, bean plants grow vigorously and have a long growth cycle, which takes more than 70 days from sowing to harvesting, and the harvesting time can last for more than two months. Therefore, beans need to be fertilized frequently throughout the entire growing period, especially requiring more phosphorus and potassium fertilizers.

In base fertilizer and top dressing, it is necessary to pay attention to the frequent application of phosphorus and potassium fertilizers. In order to obtain high yields during cultivation, it is necessary to plant in fertile soil, apply more organic fertilizers, and appropriately apply nitrogen fertilizers. Fertilizers and watering can be carried out in coordination, which can buffer fertility and reduce the occurrence of fertilizer damage.
