Why dentrifying bacteria are a blessing as well as a curse to farmers?

Dentrifying bacteria are a blessing to farmers because they help reduce the amount of excess nitrogen in the soil, which can improve soil fertility and crop productivity. However, they can be a curse when they convert nitrogen into forms that are not readily available to plants, leading to nutrient deficiencies. Balancing the presence of denitrifying bacteria is key to maximizing their benefits while minimizing their negative impacts on farming.
