SC27™ soil inoculant is a new generation of agricultural inputs available to growers in the US. SC27 microbial soil inoculant was developed to supplement and replace the beneficial soil microorganisms found in productive, fertile soils.


SC27 soil inoculant is used in the USA, Australia, New Zealand, the United Kingdom, Mexico, Central America, China, Cambodia, Indonesia, Egypt, United Arab Emirates, Panama, Canada and South Africa.
Our prescription of organisms play a critical role in soil productivity. They are the engines that drive the cycling of many nutrients. Our organisms decompose crop residues and other organic materials applied to soil. Soils with depressed microbial populations may exhibit poor physical conditions as well as lowered productivity. Conversely, SC27 soils are more productive, healthier and produce roots which increase yields.
SC27 soil inoculant was developed and refined in Australia. The organisms were selected and isolated from soils in Australia, Africa, Europe, Asia, Middle East, North America and South America.
SC27 soil inoculant contain a myriad of species and strains of rhizobacteria. Rhizobacteria are bacteria that live on the root surface and in the soil immediately adjacent to the roots.
SC27 soil inoculant contains only naturally occurring soil microorganisms. These microorganisms are isolated from soils using special techniques that require sophisticated laboratory equipment and proprietary technology.
Yes and No. Each production run of SC27 is the same as the one before. We have rigorous quality control and quality assurance procedures in place to be sure that SC27 always meets the highest standards. The product is tested regularly to make sure that it is at an optimal microbial level before it is dispatch for sale. SC27 Plus is refined by region and soil type to guarantee success in various soil conditions.

Additionally we have several variations to SC27

  • SC27 PLUS for general use
  • SC27 Turf & Shrubs for golf courses
  • SC27 PLUS Organic- currenly awaiitng OMRI organic certification
NO! There are no genetically modified organisms in SC27. All the organisms in SC27 are found naturally in the soil.
Yes, it may help improve soil structure. Our product provides the web or the “glue” that helps hold soil particles together to form stable aggregates. In other words it helps promote good soil structure.

Nutrient contamination of surface and ground water is a serious environmental issue in many areas. Soil microbes can help reduce nutrient losses by trapping the excess nutrients and preventing them from leaching through the soil or running off the soil. The nutrients are then slowly released and are available for plants to take them up.
YES – SC27 PLUS is approved for unlimited use in organic production by the Organic Materials Review Institute (OMRI). SC27 can now be used to help Organic farmers expand their operations with a major reduction in input costs.
Generally, no. SC27 soil inoculant is not a replacement for a sound nutrient management program but rather, it should be used to help promote and improve fertilizer uptake to yearly reduce fertilizer volume.
Yes, although some precautions must be taken to help assure success. Do not use a fumigant after applying SC27 or the fumigant will kill the beneficial organisms in SC27 along with the harmful organisms. Wait at least 5 days after using a fumigant before applying SC27; a longer delay may be needed with certain fumigants. Be sure to read and follow all label instruction on all soil fumigants.
Testing is underway to determine the compatibility of SC27 with various pesticides. At the present, we urge caution. Preliminary results indicate that SC27 can be applied with fungicides or used as a seed treatment when seeds have been treated with a fungicide.
No, SC27 soil inoculant should not be mixed with fertilizers because the high concentration of fertilizer will kill the organisms in SC27. SC27 can be applied with diluted fertilizer solutions such as in irrigation water or greenhouse operations.
No, the organisms in SC27 are aerobic, which means that they require oxygen. The organisms will withstand short periods of flooding, such as during irrigation but will perish if deprived of air for an extended period of time.
The optimum temperature for application is about 75 F but successful applications can be made anytime the soil temperature is acceptable for planting.
SC27 soil inoculant contains a wide range of soil microbes and may be used on a wide range of crops. Read and follow label instructions or consult our Technical advisors for the best recommendations for your crops.
SC27 soil inoculant can be used on all soil types with certain cautions. The soil must not be extremely dry because the microorganisms in SC27 soil inoculant must be able to survive and flourish. Soils that are excessively acid or alkaline may adversely affect the microorganisms in SC27 soil inoculant. SC27 can be used on soils with pH values between 5 and 9 although the organisms do best when the soil pH is near neutral. Soils should contain at least 500 ppm calcium and the organisms do best with 900 ppm calcium or more. It is important to keep soils most for at least 3 days after the application of SC27 to ensure proper proliferation
The chlorine is used to kill various microorganisms and it will kill the organisms in SC27. Be sure to flush the lines thoroughly following chlorine treatment to prevent death of the beneficial organisms in SC27.
Yes, SC27 is very effective when used in transplant operations.
The organisms in SC27 will survive on the roots of the crop for the entire growing season. The organisms live on actively growing roots so the organisms die when the crop is harvested and the roots die. SC27 should be re-applied to each crop. SC27 should also be reapplied to perennial crops that go dormant in the winter.
The organisms in SC27 colonize the roots and the application technique chosen should place the organisms in the root zone or near to the root zone. A number of application methods have proven successful.

SC27 soil inoculant may be applied in most conventional agricultural spray equipment, in irrigation systems, or injected with the seed at planting. SC27 soil inoculant may also be used as a seed treatment. Treated seeds should be planted within 24 hours of inoculation. The organisms in SC27 soil inoculant are sensitive to the ultraviolet (UV) light in sunlight so SC27 soil inoculant should be incorporated into the soil as soon after application as possible. The incorporation can be mechanical or with irrigation or rainfall. Surface soil applications should be made late in the afternoon to minimize the exposure to sunlight.

SC27 can be applied in low-volume systems such as mini-sprinklers and drip irrigation.

The recommended application rate depends on the crop being grown, the soil conditions and the crop management. Generally speaking, application rates range from 100 to 200 grams per acre. Be sure to read and follow the label instructions when applying SC27.
SC27 can be stored at room temperature (75 F) for up to twelve months. Storage at high temperatures will greatly shorten the storage life. Do not store in direct sunlight. Do not allow SC27 to freeze.
