2. Nature Theory
NATURE THEORY FOR HUMAN’S
 A Balanced Food is Medicine to the Body
&
 An Imbalanced / Excess food is poison to the Body
NATURE THEORY FOR PLANTS
 A Balanced Fertilizer is Health to the Plants and Soil
&
 An Imbalanced Fertilizer disturb both Plant and Soil Health

Macro Symbol Secondary Symbol Micro Symbol
Carbon C Calcium Ca Iron Fe
Hydrogen H Magnesium Mg Manganese Mn
Oxygen O Sulfur S Boron B
Nitrogen N Molybdenum Mo
Phoshorus P Copper Cu
Potassium K Zinc Zn
Chlorine CI
All 16 Nutrients must be present for Plants to grow

4. Nutrient functions for the plant
 The Major & Secondary Nutrients are direct food source of the Plant.
 Micronutrients act as Catalysts in several Enzymatic reactions.
 Micronutrients also act as a precursors in the Phytoalexins (Plant Immune Bodies)
production.
 Nutrients enhance the rate of cell based reactions for optimum production.
 They maintain Ionic balance and pH levels in the cell as well as in the soil.
 Nutrients play a vital role in the quality of the produce, apart from the quantity.

7. Micronutrient for the plant
Micronutrients must be available and easily absorbed by crops
 Completely soluble in water.
 Highly stable to pH changes.
 Stable and not react with others element in soil that can form insoluble salt.
 Provide desired quantity in low dose to crops.
Root
the basic support for the plant

8. Micronutrient for the plant
Disadvantage of Inorganic micronutrients
 Inorganic salts dissociated easily, these cations are very reactive and influencing by
pH condition.
 It’s easily react with phosphorous/phosphate from macro fertilizer (NPK,DAP,NP,PK),
easily react with alkali substances to form insoluble salt, insoluble form become
unavailable for the plant.
precipitation

9.  Completely soluble in water.
 Stable to pH changes.
 Prevents the Micronutrients from forming insoluble precipitates from both OH-
ions and Phosphorus ions.
 Do not disturb the reactant metal ions and other nutrients.
 Increases the mobility of plant nutrients.
 Suppress the growth of plant pathogens.
 Easy to apply (compatible with other agro chemicals).
