Rhyzo-Link solutions are the next generation in plant fertility, combining a high quality NPK fertilizer with a pure culture, poly-microbial component (PGPR) for use in a wide range of environmental conditions and cropping systems. This fertility solution is designed to provide greater nutrient utilization and efficiency via increased plant biomass, as well as better adaptability to biotic and abiotic factors which occur through numerous physical, chemical, and environmental interactions. Rhyzo-Link solutions provide a buffering or moderating “link” between soil health/ chemistry and plant productivity through efficient balance, placement, and recovery of soil/plant nutrients.

Rhyzo-Link contains Plant Growth Promoting Rhizobacteria (PGPR) which is unique to the marketplace. It is a pure culture, multi-strain, poly-microbial solution formulated to enhance fertilizer solutions. It has the natural ability to improve nutrient utilization which helps the plant to better tolerate biotic and abiotic interactions. This is done through the production and ultimate release of secondary metabolites (i.e. enzymes, lipopeptides, biosurfactants, etc.) into the rhizosphere which then impact plant processes such as nutrient availability, root hair proliferation, and systemic mechanisms. Once applied to the rhizosphere and/or phyllosphere and absorbed by the plant, it helps to promote a healthy plant with a more pronounced root system, and ultimately helps to improve crop yield and productivity. Rhyzo-Link when incorporated into fertilizer solutions, truly becomes an easy to use fertility package.

With the plant signaling mechanism (triggered by environmental conditions) via the release of root exudates, to the ultimate production of beneficial plant metabolites by PGPR, soil and plant processes are “linked” together to result in increased growth and yield by the following actions:

• improved plant vigor and stand establishment
• improved handling of biotic and abiotic interactions
• improved nutrient uptake and efficiency
• improved soil health and water use efficiency
• improved adaptive and coping mechanisms
• improved flowering and fruit quality

This all leads to increased plant yield and productivity.

The Science

Soil Rhizosphere Defined

NACHURS Rhyzo-Link is designed to build a healthy soil rhizosphere which can support increased plant growth and productivity. The rhizosphere is the narrow region of soil that is directly influenced by root secretions and associated soil microorganisms (see Figure 1.). 

The rhizosphere contains many bacteria that feed on sloughed-off plant cells, and the proteins and sugars released by roots (root exudates). Protozoa and nematodes that graze on bacteria are also more abundant in the rhizosphere. Much of the nutrient cycling needed by plants occurs immediately adjacent to roots.

Similar to fermentation, where microbes assimilate sugars and exude alcohols, our unique blend of PGPR’s transform sugars and other nutrients into useful metabolites. These include:

• Phytocompounds
  
• Siderophores
  
• Lipopeptides
  
• Microbial Antagonists
  
• Enzymes
  
• Systemic Triggers
  
• Chitinases
  

These metabolites immediately go to work in the soil to enhance nutrient uptake, lateral root growth, root hair proliferation, biotic and abiotic functionality, and systemic mechanisms within the plant, just to name a few. When the sporulated bacteria are placed in an environment which is conducive to growth, they come out of their “protective shell” and rapidly expand in number and begin producing these metabolites.

The initial deployment form of the PGPR is a bacterial endospore. The endospore is a survival mechanism employed by gram positive bacteria, including those contained in Rhyzo-Link®. The spore can be considered a defensive structure enabling the bacteria to survive under conditions too harsh for survival of the vegetative cell, which include:

• starvation
• high temperature
• pH extremes
• salt environments
• toxic chemicals

Once these bacterial endospores “germinate”, they begin normal multiplication and colonization of the rhizosphere (see Figure 3.). This gives rise to increased root and shoot growth, lateral root and root hair development, increased leaf surface area and chlorophyll content, and higher plant productivity.
