Promotes dark, green color and rapid growth; improves yield and quality of leaf crops; enhances protein content of food crops; aids in stress tolerance and disease resistance. Nitrogen is a key element to amino acids.
Stimulates early root growth; promotes early plant vigor; hastens plant maturity; influences blooming and seed formation; imparts winter-hardiness in grasses and perennials.
Imparts vigor, disease resistance and encourages rooting; aids in protein formation and fruit quality and stem or stalk stiffness; essential in formation and translocation of plant starches, sugars and oils.
Aids early root hair growth; improves plant vigor and stem stiffness; encourages seed production; in certain forms, corrects soil acidity; stimulates soil microorganisms.
Essential part of chlorophyll; necessary for plant sugar formation; acts as phosphorus carrier in plant and helps regulate uptake of other nutrients.
Essential protein ingredient; stimulates seed formation and plant growth vigor; helps maintain dark green color; aids in use of nitrogen.
Improves yield and quality of fruits, vegetables; important for seed production; assists in calcium and phosphorus use and, likely, sugar transfer in plants.
Rarely deficient in soils.
Enzyme activator; may be needed in much or high organic soils.
Associated with chlorophyll production; availability adversely influenced by over limed, alkaline, wet or cold soils.
Influences germination, plant maturity; aids in photosynthesis, carbohydrate transformation; needed for carbon dioxide absorption.
Likely needed as enzyme activator for nitrate regulation; essential in nitrogen fixation process.
Necessary for chlorophyll production and plant growth; functions in plant reproduction.
