What are Biofertilizers?

Biofertilizers, more commonly known as microbial inoculants, are artificially multiplied cultures

of certain soil organisms that can improve soil fertility and crop productivity.

Biofertilizers have various benefits. Besides accessing nutrients, for current intake as well as

residual, different biofertilizers also provide growth-promoting factors to plants and some have

been successfully facilitating composting and effective recycling of solid wastes. By controlling

soil borne diseases and improving the soil health and soil properties these organisms help not

only in saving, but also in effectively utilising chemical fertilizers and result in higher yield rates.

APPLICATION METHODOLOGY

 There are three ways of using these N-fixing/P.S.M. bacteria.

1.      Seed treatment

2.      Root dipping

3.      Soil applications

Seed treatment with Rhizobium, Azotobacter, Azospirillum along with P.S.M.

            The seed treatment can be done with any of two or more bacteria. There is no side (antogenestic) effect. The important things has to be kept in mind that the seeds must be coated first with Rhizobium or Azotobacter or Azospirillum when each seeds get a layer of above bacteria then the P.S.M. inoculant has to be treated on outer layer of the seeds. This method will provide maximum number of population of each bacteria required for better results. Mixing the any of two bacteria and the treatment of seed will not provide maximum number of bacteria of individuals.

ROOT DIPPING

            Application of Azospirillum with the paddy/vegetable plants this method is needed.

            The required quantity of Azospirillum has to be mixed with 5-10 ltr of water at one corner of the field and all the plants have to kept for minimum ½ an hour before sowing .

SOIL APPLICATION

            P.S.M. has to be used as a soil application use 2 kgs of P.S.M. per acre. Mix P.S.M. with 400 to 600 kgs of Cowdung FYM alongwith ½ bag of rock phosphate if available. The mixture of P.S.M., Cowdung and rock phosphate have to be kept under any tree shade or celling for over night and maintain 50% moisture.

PRECAUTIONS

Store biofertilizer packets in cool and dry place away from direct sunlight and heat.

Use right combination of biofertilisers

Rhizobium is crop specific, so use in specified crop

Do not mix with chemicals

While purchasing ensure that each packet is provided with necessary information like name of the product, name of the crop for which intended, name and address of the manufacturer, date of manufacture, date of expiry, batch No and instructions for use.

Use the packet before expiry, only on the specified crop, by the recommended method.

Things to remember:

Biofertilisers are live product and require care in storage

For best results use both nitrogenous and phosphatic biofertilisers

Use of biofertilizers is being empasized along with chemical fertilizers and organic manures.

Biofertilizers are not replacement of fertlizers but can supplement their requirement.
