The Importance of Calcium and Magnesium to Plant Development

Fertilizing with either dry or liquid forms of calcium and magnesium that plants can take up ("available nutrients") are indispensable for good plant growth. Plants, like all living things, have mineral requirements, Calcium and magnesium are three of the nutrients required by every plant, though in relatively small quantities when compared with nitrogen, potassium and phosphorous. 

Role of calcium in plants

Calcium plays an extremely important role in producing plant tissues and enables plants to grow better. Enriching your plants with calcium:

+ increases the plant tissues' resistance and allows for more erect stems
+ contributes to normal root system development
+ increases resistance to outside attack
+ increases the feed value of forage crops

Role of magnesium in plants

Magnesium is an indispensable mineral for plant growth, for it plays a major role in the production of chlorophyll, on which photosynthesis depends. Without a ready source of magnesium the plant cannot grow. Magnesium plays a part in many processes:

+ Chlorophyll formation
     o Light-absorbing green pigment
     o Capture's the energy of sunlight and turns it into chemical energy
     o Allows synthesis of organic compounds that are useful for plant growth and functioning
       (carbohydrates, lipids, proteins)
+ Synthesis of amino acids and cell proteins
+ Uptake and migration of phosphorus in plants
+ Vitamin A and C concentrations
+ Resistance to unfavourable factors (drought, cryptogamic disease)  

Plants that require higher calcium and magnesium levels include vegetables (tomatoes, peppers), greens (lettuce, broccoli, spinach), fruits, trees.
