A effective Sustained release biofertilizer

Background Inoculation of Plant for non-symbiotic rhizosphere bacteria for crop improvement is
complicated task.

A slow-release fertilizer releases nutrients to plants slowly over some time.

Slow-release fertilizers are usually dry blends or granular formulas, they are easy to
spread and are suitable for covering broad areas.

Sustained release fertilizer has a distinct advantage in terms of cost saving on chemical
fertilizers and liquid biofertilizer in addition to yield advantage.

Chemical slow release fertilizers otherwise may have negative effects on soil and change the soil chemistry and these soils no longer support plant growth in the long run and these limitations of chemical slow release fertiliser and liquid biofertilizer led to exploration of sustained release biofertilizer Slow-release fertilizers release their nutrients slowly after each irrigation. The benefits to the farmer are that the plants don’t receive toxic amounts of fertilizers all at once.

Technology
Gujarat Biotechnology Research Centre has developed Bead trapped with bacterial culture as Sustained release fertilizer by screening of different Strains of Nitrogen fixer for its Nitrogen
fixing ability from Bank a Bug repository.

Complete technology for the production is based on immobilization of Nitrogen fixing bacteria in a
matrix which is ecofriendly and helps in sustained release of bacteria in soil thus, rendering fertility for longer period.
