Appropriate amount of calcium fertilizer for vegetables

In recent years, umbilical rot caused by calcium deficiency has endangered vegetables, so many vegetable farmers have increased the amount of calcium fertilizer. Coupled with many dealers have also misdirected farmers: calcium fertilizer must be applied when applying basal fertilizer. This makes vegetable farmers believe that in the application of basal fertilizer, calcium fertilizer should be applied in large quantities.

In fact, it is not that the more calcium fertilizer is applied, the more vegetables will not lack calcium. Although calcium fertilizers have poor mobility in the soil and in plants and are mainly based on herbicides, the symptoms of calcium deficiency in many vegetables are not caused by insufficient calcium fertilizers. However, in recent years, large quantities of chemical fertilizers have led to the concentration of salt ions in the soil. Too high affects the absorption of calcium by vegetables. Therefore, the key to the problem is to allow vegetables to fully absorb the calcium fertilizer applied, rather than blindly increase the amount of calcium fertilizer application. And excessive application of calcium fertilizer will also change the acidity and alkalinity of the soil, which is very unfavorable to the growth of vegetables. In general, 50 kg of calcium fertilizer can be used per acre. During the fruitful period of vegetable growth, the amount of calcium required by the plant will increase significantly. At this time, calcium is added by spraying calcium-containing foliar fertilizer.
