Ecology of ,,sults from the lack of knowledge of the ecology of the root-nodule bacteria. If the appropriate host and an effective bacterium are both present in fertile land, there ought to be active nitrogen fixation. The fact that often no such appreciable nitrogen gain is evident or the fixation is insufficie

Important Limiting Factors in Soil for the ,-Legume Symbiosis,strains present in the inoculum and/or soil in relation to the species and varieties of the legume; (b) competitive ability of the introduced rhizobia in relation to the native rhizobial population; (c) ability of the host to supply its microsymbiont’s nutritional needs; and (d) environmental factor

Plant Factors Affecting Nodulation and Symbiotic Nitrogen Fixation in Legumes,d its way into the rhizosphere of an appropriate host, multiply and induce root hair curling be recognized by the plant and gain access to the root system, localize and multiply within root cells, undergo specific structural changes, and receive energy from the plant. Obviously there are many stages

Specificity in the Legume-, Symbiosis,cate genetic homology among . strains. The failures in reciprocal nodulation within cross-inoculation groups, as well as cross-infection between cross-inoculation groups, substantiates the foregoing statement.

Current Use of Legume Inoculant Technology,, primarily the development of high yielding grains, would solve the problem. Unfortunately the grains require large amounts of nitrogen fertilizer, the price of which has soared over the years because of the cost and scarcity of the fossil fuels required for its commercial synthesis.
