ULTRA FULVIC selects young leonardite with high value for agricultural production and soil remediation as raw materials, and adopts MRT molecular recombination technology to activate it, so as to improve the synergy and synergism of mineral nutrients. It is rich in hydroxyl, phenolic hydroxyl and other active functional groups, and has the functions of phosphorus, potassium and nitrogen fixation, improving fertilizer efficiency. It is extremely water-soluble and dissolves very quickly within 10 seconds. This product has strong ion exchange ability, can be compounded in the range of pH 2-12, and does not produce any precipitation under the condition of 30 degrees hard water.

Benefits

description2

• Improves soil microecology, promoting soil aggregate formation and increasing soil activity.
• Protects and promotes root growth, loosens soil, and reduces salt and heavy metal stress.
• Regulates soil pH, alleviates continuous cropping obstacles, and improves water and nutrient retention.
• Enhances fertilizer efficiency, improving uptake of nitrogen, phosphorus, potassium, and trace elements.

• Increases chlorophyll content, improving photosynthesis and stimulating crop growth.
• Increases chlorophyll content, improving photosynthesis and stimulating crop growth.
• Improves crop quality, enhancing flower and fruit quality, leaf growth, and fruit setting rate.
• Increases yield and income, stimulating crop growth potential and nutrient accumulation for high-quality, high-yield production.

Field Application Cases

description2

Treated grapevines showed enhanced root activity and nutrient uptake, resulting in uniform berries, higher sugar accumulation, and balanced growth, improving overall fruit quality.

Leaf micronutrient availability increased, iron chlorosis was reduced, and fruit set, size, and yield stability improved, supporting healthier citrus growth under variable conditions.

Root elongation and lateral branching were stimulated, rhizosphere conditions improved, nutrient absorption efficiency increased, and overall root vitality and plant resilience were strengthened.
