Answer:

 

1. Vermicompost:

Vermicompost also known as vermicast is the process of decomposition in which various species of earthworms and worms are used to decompose the waste materials such as vegetable waste. The vermicompost has more nutrients in comparison to the compost. Also, this process is faster than composting.

2. Green manure:

Green plants are grown on a farm and then mulched into the soil by ploughing which eventually turns into the green manure. The plants used for this purpose are also termed as Cover crops. Examples – Guar and sun hemp. The green manure helps in the enrichment of soil with phosphorus and nitrogen.

3. Biofertilizer:

The substances which consist of living micro-organisms such as blue green algae, Azotobacter, Rhizobium and Azospirilium in order to supply nutrients to the crop/plant are termed as Biofertilizers.
