Karnal process

KARNAL PROCESS

  • Technology developed at NDRI, Karnal. Straw treated with 4%urea at moisture level of 60%.
  • Stacked in a silo pit under cover for 30 days. A temporary loose brick structure constructed.
  • Thin layer of urea treated straw spread evenly in this structure.
  • A solution of the following composition is prepared. 60g superphosphate, 60g calcium oxide dissolved in 8 litre water. Sprinkled over the urea treated straw.
  • Inoculated with 3% Coprinus fimeratius culture.
  • Allowed to remain for 5 days then used for feeding.
  • Main advantage of this process is that free ammonia is converted into microbial protein and ligno cellulose bond is degraded.
