The role of calcium fertilizer and its application method The main role of calcium fertilizer on crops

Importance of calcium fertilizer for crops

Nowadays, many vegetable growers pay more attention to the use of calcium fertilizer. Calcium is a medium-amount element and plays a very important role in improving the yield and quality of vegetables.

For example, when tomatoes lack calcium, they will crack and are prone to navel rot. When cabbage lacks calcium, it will become dry and burnt, making it inedible. These are all related to the farmers' fertilization methods, and farmers should pay attention to the use of calcium.

How to apply calcium fertilizer

First, calcium fertilizer can be used as base fertilizer . Calcium moves slowly and should be applied as early as possible. It can only play a role in the late growth period of crops. Then calcium can be used as flush fertilizer during the growth period of vegetables. Calcium nitrate, sugar alcohol calcium, etc. can be used.

When calcium fertilizer is applied as foliar spray, it is most effective in three periods: after seedling establishment, during fruit expansion and during maturity.

In addition, the absorption of calcium fertilizer by crop roots is affected by soil moisture. If the soil is too wet or too dry, the fertilizer absorption effect is not good. Therefore, during the growth period of vegetables, watering should be reasonable, keeping the soil dry and wet. Especially before harvesting, water less to prevent calcium from not being absorbed and reducing quality.

Although foliar spraying of calcium fertilizer is quick and easy to use, the amount of foliar fertilizer used is small . For vegetables that like calcium, it cannot meet the growth needs. Therefore, when supplementing calcium for vegetables, attention should also be paid to the use of calcium in base fertilizer and root topdressing, and not too much reliance should be placed on foliar spraying.

Why is the absorption effect of calcium fertilizer poor?

When spraying foliar fertilizers, many farmers use foliar fertilizers instead of flushing fertilizers. However, this also has a great impact on the yield of vegetables. This is also a common misunderstanding among farmers when using foliar fertilizers, relying too much on foliar spraying.

Because calcium is a medium-amount element, some vegetables need more calcium. When spraying on the leaves, the amount of calcium used is relatively small, only 30 to 40 grams per bucket of water, and the absorption effect will also be affected by the environment.
