Abstract
A field experiment was conducted at
the Bangabandhu Sheikh Mujibur Rahman Agricultural University Farm, Gazipur,
Bangladesh during the aman season of July 2008 to January 2009 to investigate
the changes of soil physical and chemical properties after T Aman cultivation
with combined use of inorganic sulphur and organic sulphur as a source of
gypsum, cowdung, poultry manure and household wastes. Eight treatments were T0:
control/ no fertilizers; T1: recommended dose of fertilizers; T2: 50% S through
gypsum and 50% S through cowdung; T3: 75% S through gypsum and 25% S through
cowdung; T4: 50% S through gypsum and 50% S through poultry manure; T5: 75% S
through gypsum and 25% S through poultry manure; T6: 50% S through gypsum and
50% S through household wastes; T7: 75% S through gypsum and 25% S through
household wastes. The physical and chemical properties of the soils were
influenced directly with different treatments. The physical properties of soil-
bulk density, particle density and plough pan were decreased with combined use
of inorganic and organic sulphur. The rate of improvement of chemical
properties such as organic carbon, cation exchange capacity (CEC), total
nitrogen (N), available phosphorus (P), exchangeable potassium (K), sulphur
(S), calcium (Ca), magnesium (Mg) and sodium (Na) were higher with inorganic
and organic amendment than to inorganic alone. Separately, soil pH was
decreased to all treatments compared to control or recommended dose of
fertilizers. Based on the above results it can be suggested that the combined
use of inorganic and organic S significantly improved both the physical and
chemical properties of post-harvest T. Aman soil.
Keywords: Sulphur,
Gypsum, Cowdung, Poultry Manure, Household wastes, Physical and Chemical properties
