Soil application


Foliar application

Application of nutrients in the form of liquid to aerial parts of the plant especially to leaf
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

Important tips for foliar application
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%
IRON FeSo4 0.5%
BORON Borax 0.35
COPPER CuSo4 0.1%

ROOT FEEDING

Application of nutrients in the form of liquid directly to root of the plant

Select 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

Increased nutrient absorption by plants
Reduction in fertilizer quantity
Reduced leaching loss
Application of nutrients at the correct time
No need of extra manpower for nutrient application
