TwinN provides a combination of selected microbial species (Diazotrophs) that act synergistically to increase crop yield by supplying nitrogen and plant growth factors (PGFs). The freeze-dried microbes are revived in the rehydration solution supplied and then mixed into a larger volume of water for application to the crop by spraying onto the foliage, or application to the roots by irrigation. Because TwinN is a very concentrated preparation, each application provides huge numbers of beneficial microbes.

TwinN microbes locate to two main sites of action after application to the crop. A proportion live (as ‘endophytes’) within the plant leaves, stem and roots where they multiply and supply nitrogen and other growth factors to the plant. A second population becomes established in the ‘rhizosphere’, the zone very close to the surface of the roots and root hairs. These also supply nitrogen and plant growth factors. The dual sites of action, as endophytes and in the root zone, enable a high nitrogen fixing capacity - hence 'TwinN'.

In addition to providing nitrogen, the plant growth factors drive improved root growth so TwinN treated plants capture any additional applied nitrogen much more effectively. This reduces the losses of nitrogen fertiliser which is poorly held by soil particles and assists in enabling maintenance of high yields with reduced nitrogen fertiliser application. The microbes also act to increase the availability of other soil nutrients such as phosphorous that are often present but not available for use by the crop.
