Nucleus Complete | Advanced Soil Probiotics

Product Overview:

Nucleus Complete is produced by a fermentation process utilizing a consortium of microbes that promotes a highly productive microbial system in the soil.

Nucleus Complete can be used in conjunction with fertilizer to promote the absorption of nitrogen and critical minerals in order to increase the level of bioavailable nutrients to the root system.

Nucleus Complete provides several unique advantages including, industry-leading shelf-life stability and efficacy across many soil and environments.

Product Benefits:

  • Supports root biomass formation resulting in a more vigorous root system.
  • Enhances crop quality and yield under both favorable and stressful growth conditions
  • Contains a unique, complex and multifunctional microbial ecosystem to support a healthy soil microbiome
  • Application to plants tips the rhizosphere microbiome in favor of beneficial microbes
  • Creating a rhizosphere with robust beneficial microbes enhances the plants’ ability to overcome stresses
  • Includes microbes from different microbial families – including aerobic and anaerobic microbes – to deliver a broad range of benefits
  • Proprietary co-fermentation process of the consortium results in very stable product
