Biochar blends
Biochar blends is for creating value added products using biochar and different types of matter (living and non-living) for soil amendments and also multiple uses before ultimately reaching the soil. This is a simple chart to explore the possibilities of using biochar considering diversity of conditions in the field such as soils, types of crops, environments, climatic conditions, availability of raw materials, socio-economic, cultural, traditional, etc.


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.
Some of the advantages in this system.
Biochar would absorb the water and other soil nutrients from losses.
The harmful pesticides and chemicals from the soil are taken by biochar
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.
Highly suitable for the cultivation of vegetables, tubers, cereals, chillies, cotton, etc.
Suitable for adoption in the fields, green houses, polyhouses, etc.

The Soil Fertility Project is an interesting project that attempts to use biochar to address soil fertility and climate change both in Wales in weed eradication projects.

In the Indian project ( The participants started by using the Anila stove to product biochar, but found that it was unworkable. Now they are using a digestor to process wet waste, get some energy, and use the slurry for fertilizer. They are also using a small BiG Char unit to process green waste into biochar.


Here is a note on the concept of Biochar Urban Gardens, designed by Dr. N. Sai Bhaskar Reddy. For more details visit:


In this methods are explored for giving water and other inputs through use of biochar.

Rootigation 1 and Rootigation 2, Sapigation and Floatigation
Some of these methods are being applied in the field for mango plantation. Floatigation methods are being applied for poly houses.


Biochar compost is an excellent media for all kinds of applications. Recently I had been experimenting using biochar compost for mobile gardens and floating gardens. Although here it is used on a small scale, it could be used for large scale applications too.

Other common applications are for urban gardens

In the recent past Biochar has become popular among local media. The vernacular media is taking note and recognized the importance of biochar. We are happy that more farmers are showing interest to adopt biochar for management of their soils. About 200000 kgs of biochar compost is adopted by about 200 stakeholders in parts of India, including small and marginal farmers, tribals for horticulture, organisations, institutes and universities. This had been a seven years old Jounery for Dr. N. Sai Bhaskar Reddy: learning, understanding, designing technologies for charcoal production, biochar compost preparations, research, studies and developing methods of application. With the support of, France the process of research and dissemination accelerated. Now biochar has become 'biocharculture' with integrated wider applications for co-benefits and value addition.

With the addition of biochar compost, the cluster beans plant has grown upto 11 feet. With maximum of 20 beans in a cluster. I have not seen any records yet of such magnitude. This achievement is through the use of biochar compost. Hope the farmers could produce their own fertilizers using biochar and increase the productivity. On an average the plants have grown above 9 feet. Whereas the control plants (in plots without biochar compost) they have grown only 5 feet in height. This project is being implemented by GEO supported by, France

BIOCHAR PIT KILN is one of the simplest method of converting the crop residue and other biomass into Biochar / charcoal The farmers can easily create pits / trenches and convert the biomass residue (apart from using for compost, mulch, etc) otherwise wasted by burning in the fields openly. The tribals at Yerragondapalem (supported by NABARD / Sri Sai Educational Society), in Andhra Pradesh were trained in this method (GSBC Project), they are able to produce the biochar, preparing biochar compost and applying to their fields.

* About 30% biochar production
* 3 to 4 days for a batch of charcoal production
* Continuous hot water access (pot 1)
* Highly suitable for institutional cooking and as well making biochar
* Additional heat generated by flaring the pyrolysis gases, used for cooking
* Mitigation of the emissions during the pyrolysis by flaring
* Costs about Rs. 3000 for a 2’ width x 5’ depth x 6’ hight (in feet) “GEO Biochar pit stove”. (cost including, tin sheet for cover, digging the pit, three pot stove and chimney.)
*_"GEO BIOCHAR STOVE" is designed by Dr. N. Sai Bhaskar Reddy, CEO, GEO. Demonstrated to farmers under the project Good Stoves and Biochar Communities Project, being supported by, France
