How to Quickly Restore Crop Vigor After Stress? Mechanisms Behind ULTRALGAE Plus Stress Recovery Performance

With extreme weather events becoming increasingly frequent, crops are more often exposed to abiotic stresses such as heat, cold, and drought. Under these conditions, biostimulants have become an important agronomic tool for improving crop resilience and post-stress recovery.

ULTRALGAE Plus, developed by CityMax Group, is a compound biostimulant formulated with high-activity seaweed extracts and free amino acids. Its performance in stress recovery is based on a systematic mode of action combining signal activation, metabolic support, and nutrient synergy.

Seaweed Bioactive Compounds: Rebuilding Stress-Response Signaling

At the signaling level, ULTRALGAE Plus is produced using an enzymatic extraction process from Ascophyllum nodosum, which helps preserve naturally occurring bioactive compounds related to growth promotion and stress tolerance.

These plant-derived substances act as hormone-like signaling molecules, participating in the regulation of plant stress responses. They support the recovery of root activity, reactivation of floral differentiation, and restoration of physiological balance, allowing crops to transition more efficiently from stress-induced inhibition to normal growth under high-temperature, low-temperature, or drought conditions.

Free L-Amino Acids: Low-Energy Metabolic Support for Recovery

From a metabolic perspective, ULTRALGAE Plus contains a high concentration of free L-amino acids (≥260 g/L), which can be directly absorbed and utilized by plants.

During post-stress periods, when endogenous synthesis capacity is limited, these amino acids rapidly participate in protein synthesis, cell division, and enzyme system reconstruction. This low-energy metabolic input reduces the physiological burden on plants, accelerates tissue repair, and promotes root regeneration, fruit enlargement, and structural development.

Synergistic Nutrient Supply: Securing the Recovery Foundation

In addition to its biostimulant components, ULTRALGAE Plus provides organic nitrogen together with potassium, magnesium, iron, zinc, and boron.

Potassium and magnesium support photosynthetic efficiency and assimilate transport;

Iron, zinc, and boron are involved in key enzymatic activities and reproductive growth regulation.

This coordinated supply of organic and inorganic nutrients reinforces the nutritional foundation during recovery, helping to avoid situations where crops tolerate stress but fail to resume vigorous growth.

From Stress Tolerance to Growth Recovery: Supporting Yield and Quality Stability

Overall, ULTRALGAE Plus is not designed as a simple nutrient supplement. By integrating multiple biostimulant pathways, it enhances crop stress adaptability and recovery efficiency, providing technical support for stable yield formation and quality improvement under challenging environmental conditions.
