Golf & Professional Turfgrass |Secondary Nutrients

Plant Food Company knows the importance of maintaining proper secondary nutrient levels of CalciumMagnesium and Sulfur within your growing environment.  Our Secondary Nutrients will produce a healthier, more resilient stand of turfgrass.  When secondary nutrient deficiencies occur, the plant becomes susceptible to pathogens and is more dramatically affected by typical stress conditions.  

Calcium (Ca) is responsible for the production of healthy cell walls and is very important in the growth ofstrong roots and shoots.  Calcium also helps regulate nutrient uptake and stimulates leaf formation. It is also thought to counteract the effect of alkali salts within the plant.  

Magnesium (Mg) is a very important part of chlorophyll, which is responsible for the green color of the plant and is also necessary to produce carbohydrates through photosynthesis. Magnesium will increase iron and phosphorus utilization. When a Magnesium deficiency is present, foliar chlorosis may occur, resulting in yellowing of the plant and poor photosynthesis. 

Sulfur (S) is an essential plant food for the production of protein and the development of enzymes and vitamins. Sulfur assists in chlorophyll formation and vigorous plant growth. When sulfur is lacking, the plant exhibits intense chlorosis (yellowing).
