Is it true that crops also need calcium supplements? it is true. Crops are plants, like humans and animals, that need rich trace elements to help them grow. When crops are calcium-deficient, plant growth is hindered, and the internodes are shorter, so they are generally shorter than normal plants and have soft tissues. Since calcium has such a big effect, is it good to use to supplement calcium?

The meristems such as the apical buds, lateral buds, and root tips of crops with calcium-deficient plants first appear nutrient deficiency, which is perishable, the young leaves are curled and deformed, and the leaf edges begin to turn yellow and become necrotic. For example, calcium deficiency can cause leaf scorch disease in cabbage, cabbage and lettuce; tomato, pepper, watermelon, etc. have heart rot; apples have bitter pox and water heart disease.

No matter how much is useless, the crops are short of calcium. If we want to achieve the actual effect, what should we do?

1. Application of calcium fertilizer: for acid soil with insufficient calcium supply, feed grade calcium formate can be used to supplement calcium fertilizer on leaves.

2. Timely irrigation, prevent soil drying: autumn and winter vegetables, such as Chinese cabbage, often encounter drought, timely irrigation, to keep it moist, increase plant calcium absorption.

3. Control of fertilizer consumption: for saline alkali soil and secondary salinized greenhouse soil, the amount of nitrogen and potassium fertilizer should be strictly controlled, and the amount of once application should not be too much, in order to prevent the salt concentration of plough layer soil too high.

Although the application of different calcium fertilizers (gypsum powder, lime powder, light calcium carbonate, calcium formate) with the same amount of calcium can increase the yield of peanut, there are still great differences among different calcium fertilizers.

The effect of calcium formate feed grade in feed additives on livestock calcium is recognized by farmers. At present, it is also widely used in calcium fertilizer, because calcium formate is rich in small molecular organic calcium, has high utilization rate, fast absorption, and is not easy to be fixed by soil; it can meet the absorption of calcium during crop growth period. It can effectively prevent the physiological diseases of crops caused by calcium deficiency.

No matter how much calcium is in the soil, calcium formate is also required for ground fertilizer. Because the calcium absorbed from the soil can't reach the new leaf, the old leaf will keep itself. The use of calcium formate foliar fertilizer can supplement elements, reduce nutritional imbalance, ensure the growth of crops, and calcium formate feed grade supplement effect is also good.
