8. How to know when a plant needs
Nutrients?

9. • Soil Analysis
• Tissue Analysis
• Reduced vegetative growth – dwarf plants
• Leaves become Yellow or get curled
• Increased Pest Attack
• Yield drop Y-o-Y basis
• Plant mortality rate is high after transplanting
• Absence of earth-worms in soil

ever increasing so
where is the problem ?

ratio of Food Productivity to Nutrient Consumption
down from 14.06% to 8.59%

20. Why Chelated MicroNutrients
and What is Chelation ?

21. When Zinc is applied in soil, the following reaction may occur
2+ 3- -1
Zn + P2O5 = Zn3(P2O5)2
Zinc cation Phosphate Zinc Phosphate Precipitate
(unavailable to plant)
Diagram below shows the ability of all chelates to resist chemical
tie-up in the soil or fertilizer spray tank

24. Avoids
Avoids Avoids interference
blocking precipitation with P ( in
metal to soil of metal NPK) or in
soil

25. Sulphates Chelates
www.satyajitchemicals.com 24

26. Soil application Foliar application
to avoid blocking metal to Chelates promote transport
soil in leaves after absorption
to avoid precipitation of Chelates avoids metal
metal precipitation in hard water
can be mixed with almost all
to avoid interference with P
pesticides except Cu products

31. What should I do ?
www.satyajitchemicals.com 30

32. • Set realistic yield goals
• Use a 3 to 5 year improvement program
• Aim for annual increases of 10 to 20%
• Improve weakest practice
• Upgrade other management inputs
• Use balanced fertilization

34. Using MicroNutrients below Optimum
level, WILL :
• Reduce yields per unit area
• Mine away soil nutrients
• Reduce crop resistance to drought, disease,
insect, and other stresses
• Reduce farmer profits, thereby negatively
affecting local economies
www.satyajitchemicals.com 33

35. Some Management Practices that cost
Little or Nothing extra
• Timeliness • Tillage
• Variety, hybrid • Planting date
• Row width • Seed drop
• Fertilizer placement • Record keeping
• Scouting • Plant population

36. Higher crop yields will require to focus on
a
balanced nutrient management
