BORON(B) 0.111%

• Boron is essential for reproduction and thus seed and fruit set.
• Healthy root growth and the root response to gravity are dependent on Boron.
• Sufficient Boron enables plants to become resistant to diseases of many types.

• Poor flowering and seed set.
• The deterioration of root and stem growing points.
• Stunted roots.
• Wrinkled leaves.
• "Hard fruit disease" (especially citrus).

COPPER(Cu) 0.319%

• Copper is essential for plant respiration and photosynthesis.
• Greening of leaves.
• Development of flowers and thus seed and fruit production.
• Copper is required to control nitrogen fixation by legumes, and iron uptake by all plants.
• Copper will also help prevent wilting of leaves in dry periods.

• Poor leaf colour and deformed leaves and flowers.
• Fruit quality and production are adversely affected.
• Wilted leaves and leaves will suffer from "treatment illness".
• Citrus fruit developing thick oily skins with gum spots.
• Trees develop abnormal shoots with skew leaves.
• Up to 50% reduction in yield.

IRON(Fe) 2.260%

• Iron is needed in large quantities to produce chlorophyll and thus green leaves. Iron is therefore essential for photosynthesis and thus all growth.

• Chlorotic (yellow to white) leaves.
• The veins may remain dark green.
• Petioles of tomato plants become purple.
• Stunted growth with a drop (up to 70%) in crop yield.

MANGANESE(Mn) 0.290%

• Manganese is essential for photosynthesis and in particular, sugar production.
• Manganese also controls the uptake of other ions and nutrients from the soil.

• Chlorosis (yellowing) of the leaves.
• Leaves becoming spotted (marbled effect).
• Reduced growth and flowering.
• Cucumber, beans and many ornamentals are especially susceptible to Manganese deficiency.

MOLYBDENUM(Mo) 0.032%

• Molybdenum is needed for sexual reproduction and the development of embryos.
• Molybdenum is also necessary for the production of proteins (thus increasing the protein yield of a crop) and vitamins, in particular, vitamin C.
• Molybdenum is required for chlorophyll production and thus the greening of leaves.
• Molybdenum is essential for nitrogen fixation by legumes and for protection against aluminium toxicity in all plants.
• A seed soak will ensure even germination in the field (e.g. maize)

• Yellow/orange spots on the leaves between the veins.
• A reduced number of flowers which are small and sometimes do not open.
• Deformed reproductive organs, thus fruit and crops suffer poor yields.
• "Whiptail leaf symptom" in cabbages, etc.
• "Yellow spot" disease in citrus.
• Cabbages, cauliflower, broccoli and all legumes are most susceptible to deficiency.
• Reduction in yield of crops (up to 80%).

ZINC(Zn) 0.244%

• Zinc is essential for pollen grains and thus fertilization and fruiting.
• Zinc increases sugar production and is essential for the production of hormones.

• Zinc deficiencies are very common (especially in citrus) and are often caused by lime and phosphate applications.
• Poor growth with short stems and internodes and small, curled leaves.
• Flowers are small in size.

MAGNESIUM(Mg) 0.031%

• Magnesium is the most important component of chlorophyll ( green pigment) and thus vital for photosynthesis.
• Magnesium helps to control enzyme operations.
• Magnesium is important for oil production (e.g. avocado)

• Chlorosis (yellowing) between the leaf veins.
• In some species, the lower leaves develop a purple colour preceding death.
• Flower size and number is reduced.
• Magnesium deficiency is common after heavy nitrogen, potassium or lime application.
• Very common in tomatoes and cucumbers.
