Question

Comment on the following:
​Denitrifying bacteria are a blessing as well as a curse to farmers.​

Answer 1

1. Denitrifying bacteria is a blessing to farmers as they control the excess supply of nitrates to plants. Excess nitrates can cause harm to the ecosystem on the whole as few wild plants such as cultivated crops can live on nitrogen. ​

Nitrogen-saturated environments favor the growth of these plants that can harm the ecosystem. On the other hand, denitrifying bacteria are a curse to the farmers as they disintegrate soil nitrates to liberate free nitrogen gas into the atmosphere, hence reduces levels of nitrogenous compounds in the soil​
