EDDHA-Fe is high active chelated iron, and is more easily to be absorbed by plants.Its assimilation effect is far better than common EDTA chelated iron, and hundreds times the traditional iron fertilizer.

The fertilizer can be well absorbed by plants when the soil PH is 4.5-11(the higher the PH is, the more obvious the advantage of EDDHA-Fe to EDTA-Fe and ferrous sulphate is). The implementation effect is better when water and basic fertilizer are adequate for plants. The lacking of one minerals may result in lacking of another related microelement fertilizer, so you should make sure what is needed before you apply fertilizers, EDDHA-Fe can be mingled with other chelated microelement fertilizers such as EDTA-Zn, EDTA-Mg.

Spray on Foliage:

It is ultra efficient when you spray EDDHA-Fe to the leaves, in 1000-1500 diluted concentration, once a week, spray 2 or 3 times at a time(the spray frequency depends on the degree of lacking of iron).

1) The best way to apply EDDHA-Fe is irrigating the root by water solution of the EDDHA-Fe(consistency 0.1%). If the soil is hardened, cultivate the soil before irrigating.

2) For the north where flood irrigation is commonly used, EDDHA-Fe can be distributed into the water to irrigate the soil, once 500-1000g per Chinese acre.

3) For fruit trees or shrub, the made-up solution can be injected into the roots of the plants.

Soil application rates:

Orange……20g/plant

Apple, Peach, Pear……20g/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 depend on the size of plants and the lack of iron, the effect is better if the fertilizer is distributed into the soil and watered after earth up.

Make hydroponics liquor:

Add EDDHA-Fe 15-20g to the water to make up nutrient solution.

Attentions:

Keep in a cool and dry place.

It can be mingled with most fertilizer and agricultural chemical.

The effect is better when both watering the soil and spray the leaves with the fertilizer.

The spray should be before 9 am.or after 4 pm.,if it rains 4 hours after spray, spray again.

作物缺铁主要表现叶片失绿黄化，首先在作物的顶端幼嫩部位表现出来。缺铁一般会引起：新梢叶片失绿，在同一病枝（梢）上的叶片症状自下而上加重，甚至顶芽叶簇几乎漂白；叶脉常保持绿色且与叶肉组织的界限清晰，形成鲜明的网状花纹，少有污斑杂色及破损。严重缺铁时，白化叶持续一段时间后，在叶缘附近也会出现烧灼状焦枯或叶穿孔，提早脱落，呈枯梢状；坐果稀少甚至不坐果，果形传统铁肥的数百倍。施用EDDHA-铁可有效预防治疗作物因缺铁引起的各种生理性病害。

使用说明：

在土壤PH值4.5-11范围内植物均可良好吸收。（PH值越高，EDDHA-铁相对于EDTA螯合铁和硫酸亚铁的优势越明显。）当作物在不缺水和基础肥料的情况下，该产品的应用效果会最好。由于一种肥料的缺乏也会引发其他微量元素的缺乏，因此在施用前应对缺乏的元素进行确定，可与其他螯合微肥如EDTA-锌、EDTA-镁等配合施用。

叶面喷施：

EDDHA-铁肥用于叶面喷施效果极好，稀释浓度为1000-1500倍，1周喷施一次，一般连续喷施2-3次即可达到理想效果（喷施的次数取决于铁缺乏的程度）。

土壤应用：

1）给土壤使用EDDHA-铁最好办法是将适量的水配成溶液（浓度如0.1%），然后进行灌根，如果土壤板结，需在灌根前松土。

2）对于北方习惯采用浸灌的地区，可结合浇水将EDDHA-铁随水冲施，用量为每次500-1000克/亩。

3）对于果树或灌木，可以将配制好的溶液用压力注射器注射到植物根部。

土壤施用量：

柑橘……20克/棵

苹果、桃子、梨树等果树……20克/棵

葡萄、草莓等……100克/100米排沟

菊花、天兰葵等……50克/10平方米

杜鹃、玫瑰花、百合等……50克/丛

以上为推荐用量，实际用量应以作物的大小和铁缺乏的程度决定，如果撒施入土壤覆土后及时浇水效果最佳。

配制水培溶液：

一立方米的水可加EDDHA-铁15-20克配制成营养液直接使用。

注意事项：

本品放于阴凉干燥处密封保存，可与多数肥料及农药混配使用，缺铁地块采用土壤与叶面结合施用效果明显，与高氮肥料（尿素，30-10-10）配合使用有增效作用。喷施应在上午9时前或下午4时后进行，喷后4小时内降雨，应补喷。
