Question

State two kinds of manures.

Answer 1

Compost and vermicompost : Composting is the process in which farm waste materials such as livestock excreta (e.g., cow dung), vegetable waste, domestic waste and sewage waste are decomposed in pits to release the organic matter and nutrients. When composting is done using earthworms to fasten decomposition, the process is called vermicomposting.
Green manure: It refers to certain plants (such as sun hemp or guar) that are grown for a specific period of time and then incorporated into soil by ploughing. This process is carried out before sowing the crop seeds. The green manure (also known as cover crop) enriches soil by increasing the percentage of organic matter in soil. It mainly adds nitrogen and phosphorus to soil.
