Question

What makes cyanobacteria agriculturally important?

Answer 1

Cyanobacteria are agriculturally important because they fix atmospheric nitrogen, enriching soil fertility naturally. In paddy fields, they serve as biofertilizers by adding organic matter and producing growth-promoting substances that stimulate rice seedling growth. They also help reclaim saline and alkaline soils. Their use is simple and economical and enhances crop yield by improving soil nutrient content without chemical fertilizers.
