Properties:
Product Description: trace element chelate system using EDTA iron (Fe), Zinc (Zn), Manganese (Mn), Copper (Cu), B (B), Molybdenum (Mo), Magnesium (Mg) and other nutrients, after curing, drying, granulation, chelating, concentrated multiple refining process into.
Trace element by EDTA cgelating, exist in free form, not only as a fertilizer, water soluble fast rate, easy to be absorbed by crops, less dosage, quick effect, no residue; as raw materials, in the production of NPK compound fertilizer or other liquid fertilizer mix, easy to mix, not antagonistic, simple operation.
Special effects of trace elements for crops to resist various diseases caused by lack of other elements, is irreplaceable, a large number of elements in the NPK application amount more cases, more should be combined application of the product, with functions of greatly increase effeciency.
Physicochemical properties: grass green powder, stable performance, no hardening, non hardening, 1% aqueous solution PH value 4.5-5.5.
Quality index: 1. Fe+Zn+Mn+B+Cu+Mo ≥ 12%
MgO ≥ 8%
2. Fe+Zn+Mn+B+Cu+Mo ≥ 20%
(range of the same total can be adjusted in accordance with the indicators, user requirements can also increase the cobalt, selenium)
3. Applications:
Suitable crops: is suitable in the North South all kinds of fruits and vegetables, fruit trees and grain crops and economic crops of forestry, animal husbandry etc.
Method of use: follow a few times, suitable for thin not concentration principle, can be used n each period of crop growth and development.
1. each unit root drip irrigation: the amount of 300-500 grams, add water 1000kg of drip irrigation of crop root.
2. Spraying: Crop pre dilution concentration 2000times, 1000 times dilutied concentration late foliar, each unit dosage according to the leaf area of crops is determined, generally 30-50 grams.
3. Mixed with a large number of elements: can be mixed use, 30-50 grams per dosage; and pesticide mixture were added when please, the optimum concentration was 2000-3000 times (15 kg of water to add 5-7 grams).
4. Combination of NPK: in the NPK hybrid production, add 0.5% of the products, in accordance with requirements of indexes add liquid products.
