Quantum ExtraFos K
A liquid specialty fertilizer with a high concentration of potassium and phosphorus in the form of phosphite. The fertilizer contains highly available forms of potassium and phosphites, which increase resistance to pathogens, improve product quality, and boost crop yields. It is used for foliar feeding of field crops, fruit and vegetable crops, berry crops, and ornamental plants.
Product information
- P2O5 – 25.0% (250 g/L)
- K2O – 25.0% (250 g/L)
- pH – 5.0–6.0
- Density – 1.24–1.29
Action and Effects of Microfertilizers
- stimulates root system growth;
- provides protection against pathogens
- improves quality indicators
- increases plant resistance to drought and temperature fluctuations;
The high phosphite content in the fertilizer ensures:
- activation of key biochemical processes and plant defense mechanisms;
- a pronounced fungicidal effect by disrupting metabolism and inhibiting pathogen growth, as well as by increasing levels of phytoalexins, chitinase, and the total number of antioxidant defense enzymes;
- an increase in overall stress resistance.
Application Method
When applying as a foliar spray, the application rate of the working solution is:
- for field and vegetable crops—200–400 L/ha,
- for grapes and fruit crops—500–1,000 L/ha.
Treatments are performed using standard sprayers. The working solution is prepared immediately before application. Fill the tank 2/3 full with water and, while stirring, add pesticides and fertilizers sequentially; add Quantum ExtraFos Super last, after ensuring the previous component is thoroughly mixed.
Foliar Fertilization
When applying foliar feeding, the application rates of the working solution are as follows:
- for field and vegetable crops—1.0–2.5 L/ha
- for fruit and berry crops: 0.1–0.5 L/ha
Fertigation with drip irrigation
The application rate is 2–4 L/ha, depending on the crop and the phytosanitary condition of the plants. The first application should be made with the first spring irrigation; subsequent applications should be made at three-month intervals or as needed. Do not exceed a 2% concentration of the working solution (2 L per 100 L of water) per application.
Compatibility with other agrochemicals
Quantum ExtraFos K can be applied in combination with plant protection products and other fertilizers. It is recommended to check the compatibility of the products before mixing: a test solution should not produce any sediment. Slight cloudiness is permissible.
