Boosting forest cuttings – Unraveling the Scientific Mechanisms of Vacuum Infusion

Forests are the lungs of our planet, vital for biodiversity, climate regulation, and human well-being. Unfortunately, they face numerous threats, including deforestation, disease, and climate change. Planted forests (and of course Reforestation) are a critical solution. The unique technique called OptiBoost has gained traction recently. In this blog post, we’ll take a deep dive into the science behind vacuum infusion in forest cuttings propagation, understanding the principles and mechanisms that make it such an effective method for propagating forest cuttings. 

Understanding Vacuum Infusion

Vacuum infusion is a technique that supports propagation and leverages the principles of reduced air pressure to enhance the absorption of essential nutrients and water by plant cuttings. By creating a controlled vacuum environment, this method stimulates the cuttings to uptake the infusion solution more effectively, thereby improving their chances of successful rooting and growth.

The Key Components:


  • Reduced Air Pressure: The core principle of vacuum infusion is the reduction of air pressure within a chamber or container. When air pressure is lowered, the surrounding air becomes less dense, creating a pressure gradient. This gradient drives the movement of air and liquids from areas of higher pressure to lower pressure, allowing the infusion solution to penetrate the cuttings.
  • Infusion Solution: We have developed a functionalized nutrient solution based on the third generation of patented nanotechnology. Vacuum enables the solution to impregnate as efficiently as possible, the solution itself is optimized to deliver the highest possible amount of nutrients. These components are essential for encouraging root formation and overall growth in the cuttings. Under reduced pressure, the cuttings readily absorb these vital elements.

How Vacuum Infusion Works:

Forest cuttings exposed to vacuum infusion
The tissue is immersed in the liquid and subjected to a two-phase pressure change. The plant material is impregnated with liquid that is carefully designed to enrich the cuttings and support its optimal performance.

A specialized chamber is used, equipped with a pump to create the controlled vacuum environment. As the air pressure is reduced, it sets the stage for efficient nutrient and water absorption.

Infusion Process

The prepared cuttings are submerged in the infusion solution within the vacuum chamber. As the air pressure drops, the pressure gradient facilitates the movement of the infusion solution into the cuttings. This triggers the cuttings to absorb the solution and supports the rooting process.

OptiBoost for cuttings - SAGA Vacuum infusion System

OptiBoost for cuttings SAGA

The vacuum infusion system we offer is uniquely designed for treating cuttings, we call it SAGA. The patented system consists of one treatment unit and one control unit.

The treatment chambers is optimized to enable the nutrient solution to efficiently reach the cells of the treated cuttings. The cuttings are impregnated with the optimal amount of solution.  

The system ensures that every single cutting is thoroughly enriched with essential nutrients. By combining the right vacuum parameters and with carefully designed nutrient solutions.

The effects of OptiBoost is tangible from nursery to forest. In the end the outcome is a greater proportion of high-value trees.

The Science at Play
  • Capillary Action: Reduced pressure enhances capillary action, allowing liquids to move against gravity. This facilitates the movement of the infusion solution into the cuttings’ vascular tissues.
  • Tissue penetration: Vacuum Infusion allows nutrient solution to reach all tissue layers in plant organs. In leaves, liquid reaches deep into spongy mesophyl since that tissue is full of air spaces which can be filled with our unique solution and subsequently used by the cells to support the rooting processes.
  • Uniform application: Vacuum Infusion is a perfect way to apply the solution uniformly to every part of the plant: to reach each leaf and each stem and make sure the absorption is achieved.
Cuttings are placed in a basket and then submerged in liquid and exposed to vacuum inside the OptiBoost vacuum infusion system.

Advantages of Vacuum Infusion

  • Increased Survival Rates: Vacuum infusion significantly enhances the survival rates of cuttings, as it promotes efficient water and nutrient uptake. 
  • Controlled Environment: It reduces the risk of diseases and pests affecting the cuttings by providing a controlled environment for their growth. 
  • Indications of Faster Growth: Cuttings treated with vacuum infusion often exhibit faster and more robust growth compared to traditional propagation methods. 
  • Resource Efficiency: This method reduces the amount of water and nutrients required for successful propagation, making it more sustainable. 
  • Clonal Propagation: It is particularly useful for clonal propagation, enabling the production of genetically identical trees with desirable characteristics.
  • Boosting accuracy: ensure the accurate and optimal treatment parameters for different types of cuttings, clones, climate, etc.
  • 100% boosting guarantee: Each cutting that enters our pressure chamber is treated and provided with perfect conditions for development.

In conclusion, vacuum infusion is a technique that combines science and technology to enhance the survival and growth of forest cuttings. By harnessing the principles of reduced air pressure and capillary action, vacuum infusion offers a promising solution to address the challenges of reforestation and promote the health and sustainability of our forests. As we face environmental challenges, this innovative approach offers hope for the preservation and restoration of our precious ecosystems.
