CITYMAX Precision Solutions Unlock High-Quality Potential for U.S. Potatoes

U.S. Potatoes: Stable Yield, Upgraded Quality

In the 2024–2025 season, the U.S. potato industry is experiencing a phase of “slightly lower yields, excellent quality, and record-high exports.”

• Total production: Approximately 421 million cwt, roughly the same as last year.
• Major production areas: Idaho, Washington, and Oregon continue to lead, with Russet varieties remaining dominant.
• Market performance: Retail sales steadily increased by 2.3%, and export value reached a new high, particularly for fresh potatoes shipped to Mexico.

Nevertheless, the industry still faces challenges including continuous cropping-induced soil compaction, extreme weather, high processing standards, and labor shortages. How to maintain yields while improving quality and stress resilience is a key concern for both growers and processors.

Current Nutrient Management in U.S. Potato Production

Common nutrient management practices for U.S. potatoes include:

• Basal fertilization: Applying NPK and other macronutrients to improve the rhizosphere environment.
• Foliar nutrition: Spraying trace elements or biostimulants during critical growth stages to promote growth and improve tuber uniformity.
• Fertigation: Using drip irrigation or center pivot systems to deliver precise nutrients, reduce waste, and enhance stress resistance.

Despite these measures, traditional programs often struggle with soil compaction from continuous cropping, drought, or frost, resulting in unstable yields and uneven tuber size.

CITYMAX GROUP: Scientific Nutrient Solutions

CITYMAX GROUP offers a biostimulant + macronutrient synergy solution, covering all stages of potato growth to promote healthy roots, enhance stress resistance, achieve uniform tuber bulking, improve skin quality, and extend storage life.

• Precision Stage-by-Stage Program

Key Challenges in U.S. Potato Management

• Frost & Climate Variability

Solution: During vegetative and bulking stages, apply Ultra AminoMax + Max SeaSailer at high concentrations to enhance cold and drought tolerance.

• High Processing Standards

Solution: During tuber bulking, apply FulvoMax / Max FulvicK to improve absorption of fulvic acids, reduce hollow heart and brown spots, and ensure U.S. No.1 grade tubers.

• Automation Compatibility

CITYMAX’s fully water-soluble product series is fully compatible with center pivot and drip irrigation systems, leaving no residues and avoiding nozzle clogging, ideal for large-scale U.S. mechanized farms.

In this critical period when the U.S. potato industry is shifting from “volume production” to “quality and high value,” CITYMAX GROUP’s stage-specific precision nutrient solutions provide growers and processors with a practical, scientific, and systematic approach. By combining humic acids, amino acids, and fulvic-based biostimulants, the program improves soil health, optimizes tuber growth and quality, and delivers both yield and economic benefits.
