Agrochemical 90% potassium fulvic acid fertilizer for flowers/vegetables/crops

February 15, 2020

Potassium (K), one of the essential elements required for plant growth and development, determines leaf quality in tobacco (Nicotiana tabacum L.).  Our major objective was to enhance potassium uptake in black soils, we found that foliar application of fulvic acid (FA), one of the most bioactive humate molecules, enhanced K levels in leaves.
Fulvic acids are water soluble under acidic, neutral and alkaline conditions . Fulvic acids have a cation exchange capacity that is more than twice as great as that of humic acids .
Fulvic acids are very small, which allows them to enter plant roots, stems and leaves with more ease than humic acids or humins . Fulvic acids are often included in foliar plant applications, as they are “the most effective carbon containing chelating compounds known” .
The humin portion of humic substances is not soluble regardless of solution pH . Humin has the greatest molecular weight of any humic substance and is extremely resistant to degradation
Humic acid and fulvic acid organic fertilizer for flowers, vegetables, crops..
1. Organic fertilizer  is widely accepted as organic base manure and soil regulator in horticultural crops, fruit trees, landscaping, gardening and pasture.
2. Soil Application: 300-450kg /ha or 5-10% of total fertilizer application
3. For Turf: 200-500kg/ha
4. For Pasture: 300-500kg

Agrochemical 90%  potassium fulvic acid fertilizer for flowers/vegetables/crops
1. Soil application:

Used as base fertilizer before seedling or planting. It also can be used to improve the following soil:
(1) Alkaline soil with low iron content
(2) Sandy soils with low organic (humus) content
(3) Acid podzol soils with low humus content.
(4) Saline soils
(5) Lime soils.
When used during seedling and growth stage, should be used 2-3 times. Also, it is better to be applied with N, P fertilizers for field crop.
Dosage: 50-100 kg/Ha
2. Furrow Application
Mainly used for fruit trees. Dig a hole in root part of every tree and bury the fertilizer in the hole.
Dosage: 1-2KG per tree.
3. Seeds soaking: Dilute to 0.01-0.03% and adjust pH to 7.2-7.5. The soaking time varies from 12 hours to 24 hours according to the thickness of seeds skin, hygroscopic capacity of seeds and the surrounding temperature. The suitable temperature for seeds soaking is about 20°C.
4. Fertigation: Add it to irrigation water with the ratio of 50-100kg/Ha or with the dilution concentration of 0.01-0.05%.
