What happens to the soil fertility if some Rhizobium bacteria are added to the soil? Explain your answer
Answers
Answer:
Biofertilizers are substances that contain microorganisms which when applied to the soil increase the nutrient content and enhance the plant growth. Rhizobium, present in the root nodules of the leguminous plants, add nitrogen to the soil which is supplied to the plants to enhance their growth.

Answer: Soil organisms improve soil fertility by performing a number of functions that are beneficial for plants. In the symbiosis, rhizobia or bradyrhizobia fix nitrogen gas from the ... can break down agricultural pesticides or other toxic substances added to soil. Some bacteria and fungi produce substances during organic matter.
Explanation: Intensive agricultural practices and cultivation of exhaustive crops has deteriorated soil fertility and its quality in agroecosystems. According to an estimate, such practices will convert 30% of the total world cultivated soil into degraded land by 2020. Soil structure and fertility loss are one of the main causes of soil degradation. They are also considered as a major threat to crop production and food security for future generations. Implementing safe and environmental friendly technology would be viable solution for achieving sustainable restoration of degraded soils. Bacterial and fungal inocula have a potential to reinstate the fertility of degraded land through various processes. These microorganisms increase the nutrient bioavailability through nitrogen fixation and mobilization of key nutrients (phosphorus, potassium and iron) to the crop plants while remediate soil structure by improving its aggregation and stability. Soil structure and fertility loss are one of the main causes of soil degradation. ... Rhizobia has the capability to infect roots and induce the formation of root nodules ... soil. However, some strains of bacteria or fungi can possess more than one
