Biostimulants & Brix – sustainability from within
At Plant Quality Solutions, sustainability is not a goal but the result of good plant wellbeing. The focus is not to make every crop organic- but to make very plant strong.
A balanced plant uses energy efficiently, resists stress, and needs fewer external inputs.
By understanding the plant’s signals, we help growers create resilient, sustainable crops from the inside out.
Why- Reading the plant’s signals
Plants show how they feel through their sap.
Brix — the sugar concentration — reveals energy flow and stress levels.
High Brix means balance and strong photosynthesis.
A drop signals stress from heat, drought, or disease — the moment to support, not correct.
How- Biostimulants as natural allies
Natural biostimulants strengthen the plant’s own physiology:
- Boost root growth and nutrient uptake
- Improve resilience to stress and disease
- Maintain stable energy levels (Brix)
At PQS, we unite measurement and action in one system. We don’t follow a schedule — we follow the plant’s vitality.
What- Measurable results; benefits for plant and grower
- Stronger, more resilient plants
- Smarter use of inputs
- Sustainable growth from within
- Higher Brix, better quality, longer shelf life
- A stong image as a sustainable grower
Why PQS?
- Independent = not tied to any brand or product line
- Practical – advice you can apply tomorrow
- Experienced – in plant physiology, biostimulants, and stress resilience
- Results-driven – focused on outcome, not on sales
“By listening to the plant and supporting its natural processes, true sustainability grows – from within”.
Strawberry – Neopestalotiopsis
I just wanted to share a huge thank you for coming to Kentucky and speaking. You changed how we’re growing strawberries and our plants look great.
Choose Your Path – The PQS Flexible Advisory Model
With our Flexible Advisory Model, you choose the support level that suits your crop — from a one-time analysis to a full-season guidance program.
Each plan is built on independence, scientific insight, and hands-on experience in plant health, stress management, and biostimulant strategies.
