Take a look at the Insta-Gro Research that has enabled us to bring this fine family of products to you. Functions of Plant Food Elements

Nitrogen

Gives dark green color to plants
Promotes rapid growth
Increases yields of leaf
Improves quality of leaf crops
Increases protein content of food and feed crops
Feeds soil micro-organisms during their decomposition of low nitrogen organic materials
If supply is out of balance, with that of other nutrients, may delay flowering and fruiting

Phosphorus

Stimulates early growth and root formation
gives a rapid and vigorous start to plants
Speeds up maturity
Stimulates blooming and aids in seed formation
Helps give winter hardiness to fall seeded grains and forages

Potassium

Gives increased vigor and disease resistance to plants
Helps plants produce protein
Gives strength to straw and stalk, thus reducing lodging
Makes seed and grain plumper
Essential to the formation and transfer of starches, sugars and oils.
Increases quality of plants
Helps development of root systems
Improves quality of fruits
helps development of tubers
Aids in formation of anthocyanin (red color in leaves and fruits)
Secondary

Calcium

Promotes early root formation and growth
Improves plant vigor and stiffness of straw
Influences intake of other plant nutrients
Neutralizes poisons produced in plants
Stimulates grain and seed production
Increases calcium content in feed
In certain forms corrects soil acidity
Magnesium

An essential part of chlorophyll
Needed for sugar formation
Regulates uptake of other plant foods
Acts as a carrier of phosphate in plants
Promotes oil and fat formation
Assists in the movement of starch in the plant
In certain forms corrects soil acidity
Sulphur

Gives increased root growth
helps maintain dark green color in plants
promotes nodule formation of legumes
Encourages more vigorous plant growth
In certain forms, corrects soil alkalinity
