Integrated biological and mineral strategies for improved performance and fruit quality in commercial strawberry production

Strawberries are a high-value crop with specific nutritional and biological requirements. Consistent yields, premium fruit quality, and strong market performance depend on optimising the root zone environment and applying targeted inputs.

This article examines the synergistic role of mycorrhizal fungi, Superzyme, and boron in enhancing strawberry plant growth and production through improved nutrient uptake, soil function, and reproductive development.

Improving soil for strawberry plant growth, through mycorrhizal fungi

Commercial strawberry systems often face challenges with phosphorus availability, especially in intensively managed or lighter soils and because plants are predominately planted during the colder months when phosphorus uptake can be a challenge. Mycorrhizal fungi form a symbiotic relationship with the plant root system, expanding its functional surface area and increasing the plant’s access to phosphorus in particular, as well as zinc and other immobile nutrients in the rhizosphere.

The use of mycorrhizal inoculants at transplanting or during early root development has been shown to:

Improve early establishment and root branching
Enhance nutrient use efficiency, particularly phosphorus
Reduce fertiliser inputs through improved soil nutrient scavenging
Increase plant resilience to abiotic stress such as drought or soil compaction

Further to this, data shows inoculation of strawberries with Mycorrhizal fungi improves the fruit’s physicochemical attributes, increasing pH, soluble solid content, soluble solids/titratable acidity ratio and phenolic compounds, overall improving post harvest qualities in strawberries.

Mycorrhizal applications are most effective when integrated into soil preparation or applied directly to the root zone at transplanting.

Superzyme: Supporting microbial diversity and root function

Superzyme is a microbial biostimulant containing a consortium of living beneficial bacteria and fungi. It promotes microbial activity in the rhizosphere and supports nutrient mineralisation and availability, especially during periods of environmental stress or low soil biological activity.

In commercial strawberry production, the use of Superzyme contributes to:

Improved rhizosphere activity and soil respiration
Enhanced root biomass and fine root development
Increased access to organically bound nutrients
Better crop uniformity and reduced early-season transplant shock

Superzyme is especially useful in soils with reduced microbial diversity or in systems where regular chemistry use has led to biological suppression.

Boron support: Critical for reproductive development and calcium mobility

Boron is an essential micronutrient required for flower initiation, pollen viability and fruit set. In strawberries, boron deficiencies can lead to reduced fruit formation, uneven development and structural disorders in young tissues. Furthermore, boron plays a pivotal role in the movement of calcium and other nutrients within the plant, essential for quality fruit with good shelf life.

Adequate boron nutrition improves:

Pollen tube elongation for enhanced flower fertility
Translocation of nutrients to developing tissues
Fruit uniformity, firmness and shelf stability
Resistance to fruit distortion and cracking

Due to its immobility within the plant, boron must be supplied consistently throughout the flowering season for early fruit development. Foliar applications and fertigation are common delivery methods in commercial operations. Of course Boron is not the only mineral that enhances yield and quality and a balanced approach is always recommended with alternating mineral requirements.

Integrated approach to growing strawberries

To maximise plant health and fruit production, these tools should be implemented as part of a holistic strategy that considers soil biology, nutrient balance and plant developmental stages.

Apply mycorrhizal fungi early to establish strong, nutrient-efficient root systems
Use Superzyme to support microbial function and nutrient cycling throughout the season and to help overcome biotic stress.
Maintain boron nutrition through targeted foliar or fertigated applications during reproductive growth

This integrated approach supports enhanced strawberry plant growth, yield uniformity and fruit quality, while reducing reliance on synthetic inputs and improving long-term soil health.
