A Complete Guide to the Latest Fertilization Precautions for Edamame

Edamame is soybean; soybean is the scientific name, while edamame is the common name. Edamame is a crop that likes warmth and fears water, and it is generally planted in the summer in the south. Growing edamame requires large amounts of nutrients to achieve high and abundant yields. Therefore, in daily management, attention should be paid to frequent fertilization to add nutrients, but there are also some issues to note during the fertilization process. Let's take a look together below.

1. Fertilizer types

First, fertilization should be carried out according to the growth conditions and trends of edamame, treating the cause accordingly, such as with the most common foliar fertilizer. If edamame grows slowly, the plants are weak and small, and the leaf color turns yellow, this is a sign that edamame is deficient in nitrogen, so when spraying foliar fertilizer, nitrogen fertilizer should be the main type. Conversely, if edamame grows normally, the plants are tall and large, and the leaves are green and thick, this indicates that the nitrogen element in the edamame plant is relatively sufficient. So at this time, when applying foliar fertilizer, more phosphorus and potassium fertilizer should be applied, depending on the situation.

2. Fertilizer concentration

Not only edamame, but different plants, at different growth stages and in different places, also have different requirements for fertilizer concentration. If the fertilizer concentration is too high, it will not only fail to increase the growth rate of edamame, but will also burn the roots and leaves of edamame. When the temperature is relatively high, if foliar fertilizer is to be sprayed, the concentration absolutely must not be too high and should be around 60%. The concentration should be controlled within a range suitable for edamame. When edamame seedlings have just emerged, the concentration should be controlled below 50%, because the leaves of newly emerged seedlings are very tender, and too high a concentration will burn the leaves.

3. Fertilization time

The best time to spray fertilizer on edamame is during the growth stage when the leaves are thick and green and the plants are tall, as spraying fertilizer at this stage has the best effect. If spraying is done before the edamame plant leaves have fully matured, not only will the effect be insignificant, but the sprayed fertilizer will also be wasted. In addition, the fertilization time should be chosen in dry weather without rain, and it should be ensured that there is no water on the plants and leaves, because if there is water, it will reduce the fertilizer concentration and fail to achieve the expected effect. Spraying fertilizer in high-temperature weather will cause the fertilizer to evaporate quickly after being sprayed.

4. Spraying frequency

Many friends spray fertilizer entirely based on their own mood and time; they spray when they have time and spray whenever they feel like it. And many people also think that the more fertilizer sprayed, the better, but this is actually not the case. For example, foliar fertilizer is generally sprayed about once a week for a month, because most foliar fertilizers contain trace elements, and too many trace elements can cause trace element poisoning in edamame.

The above are some precautions about spraying fertilizer on edamame. In fact, these precautions are not only for edamame; most vegetables also apply. Even for some crops that need large amounts of nutrients to grow normally, there is still a limit. Excess will not only fail to promote growth, but will also affect the development of the crop.
