In Mexico, potato production spans highly contrasting environments—from arid northern regions to intensively irrigated western zones. Differences in climate, water availability, disease pressure, and market orientation are significant. As a result, a single management strategy is rarely transferable across regions without adjustment.

ULTRALGAE Plus, a product under the CityMax Group, is a highly effective biostimulant centred on highly active enzymatically hydrolysed bubble algae. By rapidly replenishing amino acids and synergistic nutrients, it systematically promotes crop root growth, leaf expansion, and flower and fruit development. Concurrently, it enhances stress resistance and photosynthetic efficiency, ultimately achieving comprehensive improvements in both yield and quality.

As global agriculture moves toward high-efficiency, green, and sustainable practices, improving crop yield, stress resistance, and quality has become a core goal. Chitosan oligosaccharides (COS), as natural bioactive molecules, are emerging as important tools in agricultural production. City Max Group’s independently developed COS products, leveraging advanced technology and high-quality raw materials, meet the demands of high-end agriculture worldwide.

In the agricultural inputs industry, product reliability is determined not only by formulations or marketing claims, but by the production lines that operate continuously behind the scenes.

At CITYMAX GROUP, a stable, standardized, and sustainable manufacturing system is not an exception—it is part of everyday operations.

As global agriculture accelerates toward high-quality, sustainable, and environmentally friendly development, biostimulant products have attracted growing attention from both scientific research and the market. Among them, amino acid- and peptide-based biostimulants are seeing rapid worldwide adoption due to their proven benefits in enhancing nutrient uptake, improving stress tolerance, and increasing yield and crop quality.

CityMax Group's Biometric Laboratory serves as the pivotal bridge linking research and development with field applications, providing essential support for precise product optimisation and practical efficacy validation. Within the R&D framework, the indoor biometric laboratory and sunlit glasshouse complement each other functionally, each focusing on distinct priorities. 

Soil is the foundation of sustainable crop production, while secondary soil salinization has become a long-term, hidden constraint on yield and crop quality. Under intensive modern agricultural systems, salinity and alkalinity issues not only suppress plant growth, but also disrupt soil microbial ecosystems, nutrient cycling, and root function—ultimately limiting agricultural sustainability.
