Maximise your crops’ potential with Aphasol
Aphasol is a highly effective, liquid amino acid biostimulant for foliar application.
It enhances nutrient use efficiency, stimulates root development and improves stress resilience, helping crops deliver higher yields and better quality.
Key benefits
ENHANCED NUTRIENT USE EFFICIENCY (NUE)
Improves nitrogen uptake and conversion into biomass, supporting more vigorous growth – especially when higher nitrogen is available.

Improves nitrogen uptake and conversion into biomass, supporting more vigorous growth – especially when higher nitrogen is available.
INCREASED ROOT DEVELOPMENT
Strengthens root growth and taproot vigour, enhancing nutrient and water uptake. The effect is particularly valuable later in the season when nitrogen availability becomes a limiting factor.

IMPROVED STRESS RESILIENCE
Reduces herbicide toxicity and strengthens stress tolerance through enhanced redox (glutathione) metabolism.
When applied preventively as part of a broader crop management strategy, Aphasol makes plants more resilient to abiotic stress situations such as drought and heat.
