Project indicators

The selenium-enriched potassium fuluvate is a new type of pure natural mineral active potassium fertilizer, belonging to a green energy-efficient fertilizer. It has a black appearance, foaming microporous particles, contains drug components and has the characteristics of quick-dissolving and quick-acting. Potassium fulvate is a highly efficient macromolecular organic compound. This product can stimulate crop rooting quickly and rooting more with robust growth, increase chlorophyll, Vc content and sugar content, which can resist drought, cold and disease.It also can effectively kill various underground pests and has special effects on preventing the occurrence of root knot nematode diseases. In addition, it can extend the fresh-keeping period and picking period of fruits and vegetables, prevent falling and fruit droppings, increase the sugar content of fruits and improve their quality.


1) Rapid dissolution, to promote seed germination, root growth and drought resistance 

2) Improve soil structure and increase soil cushioning. In loose and sandy soils, humic acid can increase cation replacement energy to maintain soil moisture and nutrients, so as to promote root absorption. In tight and viscous soils, it can interact with fungi to form granule structures, which will help to absorb dissolved oxygen and nutrients in the water and increase root permeability 

3) Improve acidic and alkaline soils 

4) Promote crop growth, increase yield and quality 

5) Improve the effectiveness of herbicides, insecticides and fungicides, as well as fix or reduce the residues of harmful substances 

6) Reduce the harmful nitrates that infiltrate into groundwater red, so as to protect groundwater. Humic acid fixes nitrates in the root zone to protect the underground drinking water 

7) Fix nitrogen and improve nitrogen effect (ideal additive for urea). Reduce fixation of phosphate compounds (ideal additive for monoammonium phosphate and diammonium phosphate), which can improve soil fertility and water retention 

8) Reduce pesticide residues on edible seeds or fruits

Target crops

Solanaceae beans: strawberries, cucumbers, zucchini, eggplants, tomatoes, peppers, watermelons, bitter gourds, kidney beans, beans, holland beans and green beans, etc

Leafy crops: cabbage, cabbage, celery, cauliflower, leeks, spinach, lettuce, parsley, swamp cabbage and baby Chinese cabbage

Root crops: onion, ginger, garlic, lettuce, potatoes, yams, horseshoe and beet, etc

Fruit trees: apple, pear, peach, banana, citrus, jujube, mango, cherry and grape, etc

Usage methods

For fruit trees and field crops, 5-20kg/acre, applied with base fertilizer

Applying drip irrigation, 5-20 kg per acre. Increase the dosage properly in the late growth period

Spraying: dilute 300-500 times liquid to spray evenly on the leaf surface

Various application methods can be mixed with other fertilizers. Mixing topdressing with other fertilizers should be mixed.
