SR4 Benefits

  • Improved crop quality and yield
  • Increased availability and uptake of nitrogen and phosphorus and other nutrients
  • Improved root and shoot development through the production of phytohormones
  • Improved plant vigour for better disease resistance
  • Reduced reliance on synthetic nitrogen inputs
  • Builds biologically active soils


A range of liquid formulations of ericoid fungi and plant growth promoting rhizobacteria are each tuned and tested for optimum performance in specific field crops. These fungi and bacteria are produced in sterile laboratory conditions under stringent QA control, each microorganism species in consortia is individually packed to ensure the product quality.

Please see attached trial sheets for detailed information on experimental field results.

Within as little as four weeks, ericoid mycorrhizal fungi create a huge secondary root system that will support the plant by supplying nutrients and water for its lifetime. Plants treated with SR4 will have superior water and nutrient uptake, especially in poor soil conditions, with more abundant flowers and heavier cropping, less need for synthetic fertiliser and better survival in drought conditions. better natural vigour and overall health.

Plant growth promoting rhizobacteria (PGPR) have the ability to fix atmospheric nitrogen and unlock soil-bound phosphorus and potassium as well as other nutrients. They also produce phytohormones to promote better root and shoot development. Beneficial bacteria work in synergy with AMF, which captures and transports nutrients to host plants. PGPR support a robust plant immune system for healthier crops.

PlantWorks’ research has shown that different species of PGPR give benefits to different plant types. The bacterial and fungal strains in SR4 have been specifically selected and formulated to give maximum benefit to each specific crop.
