Question

factor affecting of nitrogen fixation in briefly

Answer 1

the element nitrogen is constantly moving in a giant circle from the air through the soil into the bodies of plants and animals the atmospheric nitrogen is that converted into certain compounds that plants may take up from soil by some biochemical physicochemical like rhizobium nitrosomonas process animals get the required amount of Nitrogen from plants either directly or indirectly and the factors affecting the nitrogen fixation are PH ,salinity, moisture,temperature, microorganisms ,organic matter and soil texture the brief explanation is here for nitrogen fixation it should be converted into a picture form so it depends on the salinity of the soil and the type of soil texture is very important because the plants takes the nitrogen , moisture present in the soil is also important factor because of the moisture the nitrogen present in air converts compounds in the soil and it is taken by plants and for making compounds of Nitrogen temperature also plays a major role and the microorganisms helps to make the nitrogen compounds and helps the plants to take the nitrogen compounds through the roots ,organic matter it makes the fertility for the soil so these are the important factors for the nitrogen fixation.

Answer 2

Recent reports pointed to a decline in agricultural dependence on symbiotic nitrogen fixation, and in the use of rhizobial inoculants. The aim of the present review was to study the environmental factors that affect the efficiency of symbiotic nitrogen fixation by Rhizobium in soil. These factors included pH, salinity, moisture, temperature, microorganisms, organic matter and soil texture. The overall conclusion is that symbiotic nitrogen fixation by Rhizobium is a critical biological process. Environmental stresses are generally the limiting factors of the symbiotic nitrogen fixation. With the selection of the appropriate legume and rhizobial inoculant, nitrogen fixation can be increased and concomitantly food production can be improved even under environmentally stressed conditions.
