BIOLOGICAL TREATMENT OF STRAW
|
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 is constructed.
-
Thin layer of urea treated straw is 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 urea a NPN compound is converted into microbial protein and degradation of lignin.
