Soil application
Foliar application
It is otherwise called as Foliar feeding – Foliar nutrition
A technique of feeding nutrients to plants in the form of liquid directly to their leaves
Use Hand Operated Sprayer for Nutrient Spray
Advantages of foliar application
Require less quantity of nutrients
Low cost and Quick response - immediate effect
Uniform application is easily obtained
Deficiencies can be corrected during the growing season
Low residue
Highly efficient
Timely application – need based
Source of nutrient - Concentration - Dose
Time of spray
Good quality water
Type of sprayer
Use of Surfactants is essential
Foliar Recommendation
FOLIAR RECOMMENDATION
NUTRIENTS SOURCE CONCENTRATION
NITROGEN Urea <2%
PHOSPHORUS SSP/MAP <2%
POTASIUM MOP/SOP <2%
CALCIUM CaCl2 0.5%
MAGNESIUM MgSo4 0.5%
SULPHUR Any Sulphate FERT 0.5%

ROOT FEEDING
Application of nutrients in the form of liquid directly to root of the plantSelect pencil thickness feeding root –
white / light yellow / pink colour root – not black or dark brown
Make a slanting cut at tip of the root
Cut the tonic pocket at one corner or
add 200 ml diluted tonic to opened polythene pocket
Insert the root into the tonic pocket and tightly
tie with twine
Trunk Feeding
Fertigation
Application of nutrients / fertilizers especially water soluble fertilizers through irrigation water to the plants
Methods used fertigation
Drip Irrigation
Sprinkler Irrigation
FERTIGATION SYSTEM
Advantages of Fertigation
Application exactly at root zone
Reduction in fertilizer quantity
Reduced leaching loss
Application of nutrients at the correct time
No need of extra manpower for nutrient application
