用法与用量：
花卉：第一次每亩施用量为300克，按1克本品兑0.5升水的比例，用清水将本品完全溶解后，进行叶面喷施花卉。 豆
科植物：一个结果周期施用两次，第一次为新叶萌芽期，第二次为花落时；第一次每亩施用量为250克，第二次追肥用量减半，按1克本品兑0.5升水的比例，用清水将本品完全溶解后，进行叶面喷施。
观赏植物：参照豆科植物用法和一次用量，在新叶萌芽期施用一次即可。
果树：一个结果周期施用两次，第一次为新叶萌芽期，第二次为花落时。第一次每株施用量为30克，第二次追肥用量减半；按1克本品兑0.5升水的比例，然后施于根系土壤中，尽量使根系均匀受肥。 也可以按照以下推荐量使用：
柑橘…………30-50克/棵
苹果…………30-50克/棵
桃树…………30-50克/棵
梨树……30-50克/棵
猕猴桃………15-30克/棵
葡萄、草莓等…………100克/100米排沟
菊花、天兰葵…………50克/10平方米
杜鹃、玫瑰花、百合等…………50克/丛
其他农作物参照上述使用方法使用，一般来讲，使用量可根据作物（树）大小和铁缺乏的程度，适当增加使用量，也可在树的周围挖4-6个小坑，溶解后倒入，让植物的毛细根吸收，并立即覆土。

EDDHA-Fe ishigh active chelated iron, and is more easily to be absorbed byplants.Its assimilation effect is far better than common EDTAchelated iron, and hundreds times the traditional ironfertilizer.
The fertilizer can be well absorbed by plants when the soil PH is4.5-11(the higher the PH is, the more obvious the advantage ofEDDHA-Fe to EDTA-Fe and ferrous sulphate is). The implementationeffect is better when water and basic fertilizer are adequate forplants. The lacking of one minerals may result in lacking ofanother related microelement fertilizer, so you should make surewhat is needed before you apply fertilizers, EDDHA-Fe can bemingled with other chelated microelement fertilizers such asEDTA-Zn, EDTA-Mg.

Spray onFoliage:
It is ultra efficient when you spray EDDHA-Fe to the leaves, in1000-1500 diluted concentration, once a week, spray 2 or 3 times ata time(the spray frequency depends on the degree of lacking ofiron).
The best way to apply EDDHA-Fe is irrigating the root by watersolution of the EDDHA-Fe(consistency 0.1%). If the soil ishardened, cultivate the soil before irrigating.
For the north where flood irrigation is commonly used, EDDHA-Fe canbe distributed into the water to irrigate the soil, once 500-1000gper Chinese acre.
For fruit trees or shrub, the made-up solution can be injected intothe roots of the plants.

Soilapplication rates:
Orange……30-50/plant
Apple, Peach, Pear……30-50/plant
Grapes, strawberry……100g/100 meters row 
Chrysanthemum, geranium……50g/10 square meters
Cuckoo, rose, lily……50g/bush
The herein is recommending dosage, the actual dosage should dependon the size of plants and the lack of iron, the effect is better ifthe fertilizer is distributed into the soil and watered after earthup.
Make hydroponics liquor:
Add EDDHA-Fe 15-20g to the water to make up nutrientsolution.

Attentions:
Keep in a cool and dry place.
It can be mingled with most fertilizer and agriculturalchemical.
The effect is better when both watering the soil and spray theleaves with the fertilizer.
The spray should be before 9 am.or after 4 pm.,if it rains 4 hoursafter spray, spray again.
