ABSTRACT:
A laboratory incubation experiment of 60 days was
carried out to observe the changes of soil pH, electrical conductivity (EC),
soil organic carbon (SOC), and potassium chloride extractable nitrogen () in a soil to which three animal manures viz. cow dung (CD), chicken manure (CM)
and a combination of CD and CM had been applied at a rate of 10 t·ha－1.
The effects of manures varied with manure type and incubation period. Soil pH
slightly increased with the incubation period up to 30 days there after it
declined with time significantly (p increased
significantly (p contents when
either chicken manure alone or cow
dung and chicken manure mixed in combination. After 60 days of incubation, the highest amount of was found in
cow dung plus chicken manure treated soil followed by chicken manure treatment.
