摘要：Distillery spent wash contains nutrients and organic matter used in agriculture as a source of plant nutrientsand irrigation water. Carbon and nitrogen play an important role in increasing the agricultural production. Alaboratory incubation experiment was carried out to study the different concentrations of distillery spentwash on soil carbon and nitrogen dynamics. The treatments consisted of T 1 -Soil alone, T 2 -Spent wash @ 20kilo L ha -1 , T 3 - Spent wash @ 40 kilo L ha -1 , T 4 - Spent wash @ 60 kilo L ha -1 , T 5 - Spent wash @ 80 kilo Lha -1 and T 6 - Spent wash @ 100 kilo L ha -1 . Among the different levels, the amounts of NH 4 -N, NO 3 -N andcarbon were greater in soil that received 100 kilo L of spent wash compared to soil alone. Results shown thatapplication of spent wash not only adds mineral N and carbon to soil, but also promotes the mineralization ofsoil organic C and N, thus resulting in large amounts of carbon, NH 4 -N and NO 3 -N in soil.
