【What causes of calcium (Ca) deficiency】
(1) Acidic soils or high level of potassium and magnesium in the soil: The availability of calcium in acidic soils (below pH 5.5) is poor, potassium and magnesium can interfere with calcium uptake by plants.
(2) In a high temperature environment: Excessive drought or high salt concentration in the soil can cause poor development of plant roots, reducing the absorption and transportation of calcium. Other factors such as poor ventilation in the cultivation environment, and insufficient plant evapotranspiration due to high relative air humidity will affect calcium absorption.
(3) Excessive fertilizer or high nitrogen fertilizer: Excessive use of potassium, magnesium and ammonium nitrogen will have an antagonistic effect on calcium absorption and reduce the calcium absorption rate.
【Symptoms of Calcium Deficiency in Vegetables and Fruits】
Calcium transport in plants is very slow, mainly uptake by the roots. Once inside the roots, calcium ions are transported through evapotranspiration to other parts of the plant. While calcium is deficient, the first signs of calcium deficiency are the death of the growth points of the roots and leaves, the shrinking of new leaves, and fruit lesions.
The following are the main symptoms of calcium deficiency in fruits or vegetables:
(1) Blossom-end rot in tomatoes and peppers
(2) Tipburn in cabbage varieties
(3) Blackheart disease in celery
(4) Blossom-end rot in melons
(5) Black heart in radishes.
【Prevention for Calcium Deficiency】
(1) Apply organic fertilizers or calcium basal fertilizers.
(2) Maintain appropriate soil moisture.
(3) Apply fertilizers rationally.
(4) Use foliar fertilizers for supplementation.

Ca Strong 801(Special for Summer and Water Retention):
Ca Strong 801 is designed for the calcium deficiency crops caused by high temperature or drought. It contains a special formula can significantly improve the tolerance to the environment and with good water retention and drought resistance. Ca Strong 801 is weak acidic liquid fertilizer which help to improve the problem that fertilizer is not easy to be absorbed in hot weather. It is the preferred product for fertilization during summer.
Product Effect:
1. Adequate silicon and sugar alcohols enhance crop water retention.
2. High potassium, high calcium, and abscisic acid help regulate plant stomata to reduce water loss and adapt to drought environments.
3. Phosphorus, zinc, and Vitamin B complex promote the growth of new roots and continuously activate aging root systems.
4. Magnesium, boron, and molybdenum promote nutrient absorption and help flower buds continue to differentiate.
5. Adequate nucleotides can effectively delay plant aging.
6. Adequate betaine regulates cell walls to prevent dehydration.
7. Glucose regulates cell permeability, making crops less susceptible to water loss and more likely to survive.
8. Weak acid fertilizers help plants absorb nutrients smoothly in the summer (neutral or weak alkaline fertilizers are not absorbed by plants in the summer). |
