Exclusive M-77® Micronutrient Technology
One of the key advantages of Peters Professional fertilizers is the proprietary M-77® chelated micronutrient package.
Chelation helps protect essential trace elements and keeps them available for plant uptake, even in challenging growing conditions. This supports:
- Improved nutrient absorption
- Stronger root systems
- Enhanced chlorophyll production
- Healthier foliage
- Improved plant vigor
- Reduced risk of micronutrient deficiencies
The result is more consistent growth and better overall crop performance.
Acidifying Action Helps Improve Nutrient Availability
Many growers face challenges with elevated pH levels, particularly when growing in mineral soils or using alkaline irrigation water.
Peters Professional 20-20-20 provides an acidifying effect that helps:
- Improve nutrient availability
- Reduce micronutrient lockout
- Support healthy root function
- Maintain optimal growing conditions
- Promote more efficient nutrient uptake
This makes it an excellent choice for growers looking to manage pH while providing complete nutrition.
