		Nano Chelated Magnesium	10-30 g/per tree
		Nano Chelated NPK 20-20-20	10-15 g/per tree
		Nano Chelated Nitrogen	20-200 cc/per tree
2	Flower induction or bud swelling (first fruit set)	Nano Chelated Fruit Set	2 g/L	Foliar spraying
2	Flower induction or bud swelling (first fruit set)	Nano Chelated Complete Micro	1.5 g/L	Foliar spraying
3	After the third stage of flower drop	Nano Chelated NPK 20-20-20	4 kg/ha	Fertigation
3	After the third stage of flower drop	Nano Chelated Complete Micro	2 kg/ha	Fertigation

6	Before harvest	Nano Chelated Calcium	2 g/L	Foliar spraying
7	After harvest (second fruit set – before autumn)	Nano Chelated Fruit Set	2 g/L	Foliar spraying

Notes

The recommend amounts of fertilizers applied through deep delving are according to the age of trees between 8-20 years old. For those above 20, the required amount is the same as 20 years old.
The application amount of Khazra Nano Chelated Complete Micro fertilizer through deep delving for trees younger than 8 years is 10 g for each year.
Avoid applying Khazra Nano Chelated Boron fertilizer in areas where the irrigation water/soil is salty or boron in water/soil is more than normal, and instead, apply Khazra Nano Chelated Complete Micro fertilizer.
In areas where early frostbite may strike the orchard after harvest, applying Khazra Nano Chelated Potassium fertilizer (1 g/L) instead of khazra Nano Chelated Nitrogen fertilizer is recommended so as to make citrus trees resistant.
Generally, the simultaneous foliar application of Khazra Nano Chelated Calcium fertilizer with other fertilizers, except for Khazra Nano Chelated Boron fertilizer, is not recommended.
At each stage, the cases must be applied together.
