'Perchigation' is a means of creating a shallow aquifer using biochar for irrigation.
The advantages are:
It is highly suitable for semi-arid and arid areas to prevent evaporation of water.
Prevent water going deeper into the aquifers there by the ultimate water reaching the plants is limited.
Biochar would absorb the water and other soil nutrients from losses.
The harmful pesticides and chemicals from the soil are taken by biochar
Emissions from the soil are reduced
The rainwater is harvested in the ‘biochar aquifer’ created.
The water can be recycled through recovery.
The water gets purified due to biochar in the areas where polluted water is used for irrigation.
Carbon sequestration as the life of biochar is high.
Highly suitable for the cultivation of vegetables, tubers, cereals, chillies, cotton, etc.
Suitable for adoption in the fields, green houses, polyhouses, etc.
