What are the symptoms of calcium deficiency in crops?

1. When plants are calcium deficient, root growth is inhibited, the front end of the root turns brown, the branches and leaves grow too long and become soft, and in severe cases, they die (only white roots can absorb nutrients from the outside world).

2. The internodes of the plants are short, premature, easy to lodging, not fruitful or less fruitful, and fruit trees generally show cracked fruits. Grain crops show thin and small leaves, poor cold and drought resistance; thin stems are easy to lodging, small ears and unfull grains, low yield and poor quality.

3. The leaves are small, dark green and dull, the young leaves are deformed and curled, and the leaf tips appear hooked. In severe cases, the leaf edges turn yellow or even burn and necrotize.

4. The first symptoms are on the root tip, terminal buds and young leaves. In severe cases, the terminal buds are necrotic.

5. After calcium deficiency, nutrition is unbalanced, new shoots mature poorly, the tree becomes weak, the accumulation of sugar in the fruit is affected, the fruit powder is less, and the fragrance is weak. The fruits are easy to soften and fall off and are uneven in size. They are prone to falling and cracking, and the storage and shelf life are shortened.

General causes of calcium deficiency in plants：

1. Low calcium content in the soil.

2. High salt content in the soil affects the absorption of calcium by the roots.

3. Soil drought. Crops are prone to calcium deficiency under drought conditions because drought concentrates the soil solution, increases the concentration, reduces water absorption by the roots, and thus inhibits calcium absorption.

4. Excessive application of nitrogen fertilizer, because excessive one-time use of nitrogen fertilizer will increase the salt concentration of the soil solution and reduce calcium absorption. In addition, excessive application of ammonium nitrogen will inhibit calcium absorption, thereby aggravating calcium deficiency.

 

How to supplement calcium for crops most effectively?

 

1. When buying calcium fertilizer, look for regular corporate brands and apply more calcium fertilizers. Calcium formate produced by Zibo Amila Company is a highly efficient calcium fertilizer that can provide plants with the necessary calcium element. Under drought conditions, calcium formate can slow down the transpiration of crop water and enhance the drought resistance of crops; under cold conditions, calcium formate can enhance the cold resistance of crops, so that they can still grow normally in low temperature environments; on saline-alkali soils, calcium formate can reduce the salt concentration in the soil, improve the soil structure, and increase the permeability of the soil. In short, as a new type of fertilizer raw material, calcium formate has many advantages in agricultural calcium supplementation. Its high calcium content, good water solubility, role in regulating soil pH, and multiple functions such as drought resistance, cold resistance, and salt-alkali resistance make it play an increasingly important role in agricultural production.

2. Determine a reasonable time for calcium supplementation according to the demand time of different crops. For example: Apple soil supplements calcium fertilizer in autumn fertilization and bud fertilizer. It is recommended not to use it in extreme drought, heavy rain, frost and crop flowering period.

3. Pay attention to climate change. If there is continuous snowfall in winter, pay attention to calcium supplementation for greenhouse vegetables. Field crops should pay attention to calcium supplementation on the leaves when encountering long-term drought and continuous rainfall. Orchards with closed growth should open the light path through pruning to promote calcium absorption.
