Assessment of Organic and Inorganic Carrier Material Based Biofertilizers: A Review

Biofertilizers are produced as carrier-based inoculants, due to their effectiveness, simplicity of handling and long-term storage. The carrier material utilised has a significant impact on the efficiency and effectiveness of a biofertilizer. Appropriate carrier materials provide an appropriate environment for replace the enhanced microbial activity. As a result of the unique biological fertilizer synthesis, organisms can be utilised as biological fertilisers at the farm level for a long period in many planting sequences. The survival rate of microbial inoculants delivered into the soil profile system is affected by physico-chemical properties such as moisture level and type of carrier materials. The substrate serves as a catalyst for the transition of microorganisms from the control condition to the rhizosphere zone of agricultural fields. Use of organic or inorganic based carrier material results in a silica-rich environment that benefits plant growth and overcomes abiotic and biotic challenges by avoiding shedding. Additionally, use of carrier-based biofertilizer results in appropriate nutrient availability, good water retention capacity and the generation of chemicals that promote and regulate plant growth.
