摘要
This invention relates to a process for the storage of a VAM (Vescicular Arbuscular Mycorrhiza) biofertilizer characterized by the steps of subjecting colonized roots of the same to the step of pre freezing with cryoprotective agent so as to protect the roots from freeze injury wherein the step of prefreezirig consists of slow cooling the roots to a temperature of -30±2°C at a rate of 1-3 °C/min, subjecting the colonized roots to a primary step of freeze drying wherein primary freeze drying is carried out at -100 + 2°C for a period of 10-12 hours and then to a secondary step of freeze drying which is carried out in a lyphollizer and till the chamber pressure is approximate or equal to that of condenser pressure which is below 150 psi units.
