Biofertilizer: present and future perspective in Bangladesh

Abstract

Global food security is seriously threatened by a number of issues facing modern intensive agricultural methods. Chemical fertilizers are rigorously used to boost agricultural output in order to meet the nutritional needs of the world's growing population. The quality, physical characteristics of agricultural soils, their chemical properties and biological health, are extremely deteriorating. Plant-associated microorganisms hold great promise for resolving these issues. Soil microorganisms play a key role for plants and supply nutrients in proper ways, like ions form are very much essential to uptake. In this article, present situation of biofertilizer demand, availability, farmers knowledge, use and future perspective are briefly described. Types of biofertilizer, active inoculum like Rhizobium, PSB and VAM fungi, modern microbiome’s activity and ecology study procedures though ¹⁸O water or ¹³C use in Stable Isotope Probing (SIP), Quantitative Stable Isotope Probing (qSIP) method and NGS, qPCR techniques are also discussed. This article showed mechanism of biofertilizer, phytohormone regulation and some of advantageous processes of biofertilizer in improved plant growth. The forms of using microbial strains as biofertilizers is rigorously illustrated. The potential of biofertilizers as tools for sustainable agriculture and calls for wider use to increase crop yields and environmental resilience.
