微生物用于提高营养物质的可用性，即，氮（通过固定大气氮），作物被称为生物肥料。近年来，生物肥料已成为生物固氮的重要组成部分.它为增加养分供应提供了一条经济上有吸引力和生态上无害的途径。植物生长促进物种通常用于提高作物产量。除了农业用途外，在环境应用方面也有潜在的好处。因此，豆科植物、蓝绿色藻类（BGA）或蓝细菌和满江红（含有共生固氮BGA的蕨类植物，即，在农业生产中，固氮菌（Azotobacter /Azoacetyllum）和红萍（Azolla Anabaena Azollae）对水稻和水稻的生长具有重要作用。
Microorganisms employed to enhance the availability of nutrients, viz., nitrogen (by fixing atmosphere N ), to the crops are called biofertilizers. In recent years, biofertilizers have emerged as an important 2 component for biological nitrogen fixation. It offers an economically attractive and ecologically sound route for augmenting nutrient supply. Plant growth promoting species are commonly used to improve crop yield. In addition to their agricultural usefulness, there are potential benefits in environmental applications. Thus various species of Rhizobium for legumes, blue - green algae (BGA) or cynaobacteria and Azolla (a fern containing symbiotic N - fixing BGA, i.e., Azolla Anabaena Azollae) for wet land rice and Azotobacter / Azospirillum for 2 several crops can play significant role in agriculture.
