Chelated Zinc EDTA Fertilizer
Soil Application Recommendations:
Vegetable Crops (including beans, celery, cucumbers, lettuce, melons, onions, peas, peppers, potatoes, sweet corn, tomatoes): 4 - 12 lbs. per acre.
Field Crops (including alfalfa, corn, dry beans, peas, forage grasses, rice, safflower, sorghum, sugar beets, sugarcane): 4 – 12 lbs. per acre.
Tree and Vine Crops (including almond, apple, apricot, avocado, berry, cherry, citrus, grape, mango, olive, pear, peach, pistachio, plum, walnut): 4 - 15 lbs. per acre or 1 - 4 oz. per inch of tree diameter.
Ornamental Shrubs and Trees: (including azaleas, gardenias, junipers, pines, roses): 2 tbsp. for small shrubs and up to 2 tbsp. per inch of tree diameter for large trees and shrubs.
Turf: 1/2 lb. per 1,000 sq. ft. or 22 lbs. per acre.
NOTE: The rates given above are based on broadcast application. If broadcast rates are used for spot or banded applications, phytotoxicity may result.
Foliar Application Recommendations:
Trees (Citrus): Apply 1 - 2 lbs. per 100 gallons of cover spray any time except during bloom.
Trees & Vine Crops (Excluding Citrus Trees): Apply 1 - 2 lb. per acre in sufficient spray volume for thorough coverage (25-gallon minimum) at dormant/delayed dormant before bloom, then after full bloom at 2 3-week intervals as needed.
Note: For smooth skinned fruit (peach, pear, apple, etc.) apply 1 lb. per acre in 50-100 gal. of water.
Vegetable & Field Crops: Apply 1/3 to 1-1/3 lb. per acre in sufficient spray volume for thorough coverage (25-gallon minimum).
Turf: Apply 1-4 oz. per 1,000 sq. ft. in sufficient spray volume for thorough coverage.
Zinc is an essential micronutrient for plants growth. Zinc fertilizer usually comes in two forms: Chelated Zinc EDTA and Zinc Sulfate. Because Chelated Zinc is readily available for plants to absorb, it will improve zinc deficiencies faster.
Chelated Zinc EDTA fertilizer is compatible with other fertilizers and nutrients and is ideal for maintenance application before deficiency appears. Chelated Zinc EDTA is highly efficient and available to support plant growth, resulting in higher yields. This fertilizer can be used from seedlings to the mid-season application which can be done through irrigation or foliar sprays.
In addition to being highly water soluble, Chelated Zinc EDTA holds onto trace elements thus preventing precipitation with other components. This ensures adequate absorption by leaves, roots, and plants tissue with a broad compatibility. It is compatible and useful in a wide range of crop field, but it is best for hydroponic agriculture. While Chelated Zinc EDTA can be used for a number of growing methods, if you are growing hydroponically, Chelated Zinc EDTA is the most effective zinc fertilizer.
Main Features and Benefits of Chelated Zinc EDTA:
- Has highly and fully chelated zinc elements
- Is quickly taken in by plants since it requires low energy to absorb the nutrient
- Contains organic substance with a minimum salt index
- Contains highly and readily available nutrients
- It starts working right away
- Is highly compatible with nutrients and other fungicides
- Can be used both in hydroponics agriculture and for soil application
Chelated Zinc EDTA can be safely applied by spraying, as a liquid fertilizer, as a side dressing or through irrigation delivery systems. You can be assured that the nutrients will last long after binding with EDTA chelate.
Role of Zinc (Zn) in Plants
Zinc is responsible for activating the enzymes which help in synthesis of protein in plants.
This is used in the formation of chlorophyll and conversion of starches to sugar in plants which helps crops in withstanding cold temperatures.
It is also vital in the formation of auxins which are responsible for stem elongation and growth regulation.
What Happens When Plants Are Zinc Deficient?
Zinc is immobile meaning that lack of zinc shows its symptoms on new leaves. These symptoms differ depending on the type of crops.
The primary sign is chlorosis for the fresh leaves which is a condition associated with lack of chlorophyll.
It is also related to the formation of necrotic spots on the leaf margin or tips.
The leaves of the plants may shorten making the plant to have a rosette appearance.
Zinc deficiency may also result in poor budding leading to low flowering thus decreased fruit harvest.
Why is Chelated Zinc EDTA Better Than Zinc Sulfate?
Chelated Zinc EDTA is stronger than Zinc Sulfate, and it is highly soluble in stable water.
Also, it is stable in alkaline and acidic conditions meaning it is available for plants at a wider range of pH levels.
Chelated Zinc EDTA releases cations and has a high affinity with lead which plays an essential role in detoxification of lead in plants.
This prevents plants from the toxic effects of lead.
