Answers
Answer:
blue green algae fix the atmospheric nitrogen which increase the amount of nitrogen in soil hence fertility. bacteria digest the waste material which act as manure.
Answer:
Blue-green algae can fix atmospheric nitrogen. They fix the atmospheric nitrogen in form of nitrates which can be absorbed by the plants.Micro-organisms are the most essential resource for a farmer because they nourish soil with essential nutrients. Soil contains numerous minerals in forms which plants cannot absorb directly. Microbes like fungi and bacteria with the help of their enzymatic machinery break down these minerals into forms that can be absorbed by crops. Along with essential elements, microbes also provide one of the most influential factors required for overall development of plants - plant hormones. Some of these plant hormones play crucial roles in seed formation, growth and ripening. These hormones also impart immunity against invading pests.
