Through Fly Ash Utilization

Fly Ash Soil Amendment Technology (FASAT)

CFRI has developed fly-ash soil amendment technology (FASAT), which has been extensively demonstrated through field trials under different agro-climatic conditions and soil types in different parts of the country for cultivation of various cereals, oil yielding, root, leguminous and vegetable crops in actual agricultural fields/waste land and/mine spoil and for growing different plant species and established the following advantages:

• Improvement in physico-chemical properties of the soils
• Substantial increase in crop yield (20-60%)
• Early maturity of crops.
• Higher nutritional value of the crops.
• Less pest incidence.
• No carry over of the trace/heavy metals/radioactivity beyond permissible limits and without any other adverse effect.
• Encouraging growth performance of various plant species including the timber, oil yielding, fruit bearing and ornamental and medicinal plants.

This technology covers the following areas:

Waste Land Reclamation

Waste/degraded land/low lying areas near in the vicinity of different TPPs viz. Farakka STPP, Bhusawal TPS, Chandrapur STPP, Harduaganj/ Obra/ Anpara TPPs of UPRVUNL, NLC and in the State of Jharkhand have been reclaimed and made suitable for crop farming /social forestry /medicinal plants through bulk use of fly-ash. Fly-Ash has been established to act as excellent soil conditioner/ modifier.

Reclamation of Mine Spoil/OB Dumps

Mine spoil/refuge in the vicinity of different mines such as BCCL, NLC, MCL have been successfully reclaimed using the FASAT and other amendments depending on the fertility of the mine spoil/refuge and various crops and plant species including timber, oil yielding, fruit bearing and ornamental, and medicinal plants have been grown with encouraging growth performance and established the suitability of the technology for crop farming/social forestry through bulk use of fly-ash.

Bio‐restoration of abandoned Ash Pond/low lying area

Technology for restoration of biological system in abandoned ash pond and make it productive and suitable for agro-forestry purpose via biotechnological methods in eco-friendly manner has been successfully developed.

Approximate Cost of FASAT package: Rs 25,000.00 per acre, including transportation of pond-ash up to 25 km @ 50 t/ha
(The figure is indicative only and will vary depending upon soil types and agro-climatic conditions and distance of ash transportation).
