Culbac® Probiotic Plus™Culbac® Probiotic Plus™ is a proprietary beneficial bacterial fermentation product that has undergone a special processing and is enhanced and stabilized to support the growth of good bacteria and minimize pathogens that can negatively impact your soil, plants or animals. Additional vitamins, minerals and amino acids are added to the formulations for extra benefit.  Products for Seed Treatment, Plant Health, Crop Health, and Soil Health

Whether you are growing field crops, farming fruits and vegetables, or maintaining turf on a golf course, all-natural Culbac Plant products are scientifically tested and shown to deliver results safely and effectively.

Derived from a unique combination of fermented bacteria and seaweed extract, these products include naturally-produced plant growth regulators which encourage vigorous root and shoot development. This encourages robust root development, overall plant health and enhanced plant immune systems (yes, plants have an immune system too).

Culbac Probiotic Plus products include safe and easy to use soil amendments, root dips, seed treatments and foliar sprays and are available in both liquid and dry forms.

Research has shown Culbac® Probiotic Plus™ Plant products:

What does this mean for my crops?

  • The exocarpAn exocarp is the outermost layer of the pericarp of a fruit. (or outer skin) is shinier, stronger, and more protective for longer shelf life
  • The mesocarpA mesocarp is the middle layer of the pericarp of a fruit, between the endocarp and the exocarp. (or fleshy, meaty part) is more abundant and maintains water and nutrients for a sweeter fruit
  • The pericarpA pericarp is the part of a fruit formed from the wall of the ripened ovary. (mostly in berries – the fleshy fruits) promotes growth and nutrient uptake
  • The fruits of the stalk are larger, denser, and have better protection against harsh weather
  • The stalk is healthier with strong endophytesAn endophyte is a plant, that can be a bacteria or a fungus, which lives inside another plant. Typically they help support plant health and immunity. and remains pliable even in harsh conditions
  • Improved germination and larger root mass provide more nutrients to the plant
  • All this leads to more bushels per acre
  • The root capA root cap is a type of tissue at the tip of a plant root. It is also called calyptra. Root caps contain statocytes which are involved in gravity perception in plants. The root cap is resonsible for durability of penetration through the soil. The root cap protects the growing tip in plants. is durable and can proliferate even in difficult soil types
  • Better absorbance of nutrients and moisture at the roots
  • xylemXylem is one of the two types of transport tissue in vascular plants, the other being phloem. The basic function of xylem is to transport water from roots to stems and leaves, but it also transports nutrients.(core) and phloemA phloem is the vascular tissue in plants that conducts sugars and other metabolic products downward from the leaves.(flesh) integrity and nutritional uptake
  • Enhances root integrity to improve “liftability” of sod at harvest
  • Promotes the establishment of sod plugs
  • Improves coverage (to fill in unsightly bald spots in lawns)
  • Strengthens durability and survivability in high traffic areas on the golf course

How do Culbac Plant products work?

Culbac Plant products contain growth regulators like cytokininCytokinins are a class of plant growth substances that promote cell division, or cytokinesis, in plant roots and shoots. They are involved primarily in cell growth and differentiation, but also affect apical dominance, axillary bud growth, and leaf senescence.  , microminerals, macrominerals, amino acids, and they also stimulate beneficial microbes in the rhizosphere. The fermentation metabolites in Culbac Plant products boost the populations of good native microorganisms in the soil. These beneficial microorganisms are essential for converting soil nutrients into forms that the plant will absorb, take up and use.

What makes our products different from the competition?

Culbac all-natural plant treatments act as stimulants on either the seed, root, or plant.

These products include a plant growth regulator called cytokinin . Cytokinin acts as a biostimulant product and encourages vigorous root and shoot development. By encouraging more vigorous root and shoot development, your seeds and plants take in nutrients more efficiently and produce a more robust and quality crop.

Our unique formulation acts to strengthen the root cap (so your plants can thrive even in difficult soils), encourage the tap root extension, and stimulates more secondary root growth, tertiary root growth and abundant root hairs for uptake of water and nutrients.

The additional stimulation of the positive soil microbiome (all the good bacteria in the soil) means that soil nutrients and minerals are released to be available to the roots. You would need to buy several competitive products to gain all the benefits available from a single Culbac offering.

Additionally, Culbac all-natural plant treatments have been scientifically proven to: 

Enhance root development
Promote crop maturity
Promote earlier emergence and increase seed vigor
Support beneficial microbial activity in the rhizosphere
Increase crop yield
Increase stress resistance

Culbac Plant products have natural biostimulants derived from a unique fermentation of bacteria and seaweed. Because our specific nutrient additives and our extended fermentation periods nurture the formulation, Culbac provides the most immediately available useful vitamins, amino acids, enzymes, and nutrients available for production benefits on your farm.

Our products are naturally effective, safe and sustainable

Dried Soybean Plants

Culbac Plant products are also environmentally friendly. 

The seaweed used in TransAgra’s fermentation process is Norwegian brown kelp (Ascophyllum nodosum), an abundant and renewable bio-resource from the coasts of the North Atlantic. 

Culbac Plant products are natural, non-toxic & biodegradable. 

They do not harm plants, pets, pollinators or wildlife when used as directed.  Moreover, their root-boosting qualities provide the maximum amount of soil nutrients to the plant, where they are most needed.  This helps prevent excess nutrients in run-off and keeps nitrogen and phosphates out of watersheds, streams and lakes.
