RhizoN is rhizobium inoculant for legume crops nodulator


Rhizobium inoculant to improve the nitrogen-fixing ability of legume seeds

RhizoN is rhizobium inoculant for legume crops seed treatment (e.g., beans, peas, lentils, peanuts, cowpea), with biological nitrogen fixing organisms Bradyrhizobium Sinorhizobium, form a symbiotic relationship with the roots of the plant, establishing nodules in which they multiply and fix atmospheric nitrogen. These legume nodules act as factories for the production of ammonia, which is used by the plant for growth. Where to buy rhizobium inoculant, Novobac is reliable manufacturer supplies both granular and liquid inoculant for soybeans.

Mode of Action

RhizoN nodulator inoculant for soybeans is a soil inhabiting bacteria capable of fixing atmospheric nitrogen compounds in symbiotic association with legumes. They host plants in all these cases have healthy appearance. It can trap level of 20-40 kg nitrogen per hectare and thereby helps to reduce the amount of synthetic fertilizer usage; increasing the productivity of pulses and fixing nitrogen into the soil for subsequent crops.

To establish this relationship, the rhizobium bacteria must first colonize the roots of the legume plant. This typically involves attaching to the surface of the roots and producing chemicals that stimulate the plant to form nodules. Once inside the legume root nodules, the bacteria multiply and fix nitrogen, which is then provided to the plant in a form that it can use for growth.


  • High levels of advanced rhizobium inoculant in a ready-to-use liquid formulation
  • Sterile production ensure more than 200 million rhizobium bacteria per ml
  • Improved plant health and higher yield potential
  • Ensure maximum nodulation and biological nitrogen fixation
  • Improve water retention
  • Boosts germination and root growth

Application Rate

Soil Application:

– Horticulture apply 1 L/ ha, Apply every 4 weeks or as required

– Broadacre (liquid inject at planting) apply 0.5 L/ ha at planting

Seed Treatment

– Horticulture apply 5 mL/ kg of seed, just prior to planting

– For large-scale application, treat seed with 2 liters / tonne of seed just before planting

Seedling treatment

– Soak seedlings in a solution of 1 ml per L, just before planting

How to apply rhizobium inoculant

  • Slurry Application: Apply at a rate of 500 ml/100 kg , mix the RhizoN liquid inoculant with conditioner, Biostart, and dechlorinated water in a tank, stir well in a clean container for form a lump-free slurry. Do not allow slurry to settle out. Pour onto seed and mix thoroughly to ensure evenly coated. Allow seed to dry before further handling. The slurry should ideally be used on the same day it is mixed, or within 24 hours at the latest. It is important that the temperature of the slurry does not exceed 20°C. Ensure seed is clean to prevent clumping.
  • Wet inoculation method: Applied at a rate of 200 ml/100 kg without the need for extra water, mix the damp seed thoroughly with the nodulator inoculant for soybeans to ensure evenly coated, as long as the total liquid volume being applied (including all other seed treatment active ingredients, polymers, and colorants) is at least 326 ml/100 kg of seed. RhizoN can be applied using a wet sequential method (also known as simultaneous), using a separate application tank for the active chemicals/polymers/colorants (preferred), or using a tank mix.
  • To minimize the risk of damage to the rhizobium bacteria during application, it is recommended to lightly irrigate the soil if it is especially dry at planting time. If planting conditions are adverse or stressful (e.g., hot and dry field conditions), it may be helpful to increase the liquid inoculant application rate.

Keep stored in a cool and dark place, with a temperature range between 4°-25°C (40°-77°F). Avoid storing it in direct sunlight and keep it at floor level for better temperature control. It is also important to use the inoculant within 24 hours of opening it and to make sure it has been stored properly before use. Do not use an inoculant that is past its expiration date or that has not been stored properly.
