Answer Details
The disadvantage of using organic manure on the soil is the spreading of pests and diseases. Organic manure may contain pests and diseases that can be harmful to plants and crops, and when spread on the soil, it can introduce these pests and diseases into the soil, which can then affect the growth and health of plants. Therefore, it is important to ensure that the organic manure used is properly composted and free of pests and diseases before it is applied to the soil.
