**7.1 Limitations in use of organic manures alone**

• Limited effectiveness of organic fertilisers as they release nutrients into the soil with the help of microorganisms that break down the fertilisers slowly. And for the microorganisms to break down the organic fertilisers effectively, they need warmth and moisture. If the soil is not warm or moist enough, the breakdown of the organic fertiliser will take time and its effects will be limited.
