Abstract
The effect of the Fertilizer Industry Waste Gypsum Material (FIWGM)
on the rehabilitation of barren soils has been investigated with this
research. The soil improvement tests were carried out in randomized
blocks with three replications and 0, 20, 40 and 60 tons ha-1 of FIWGM
have been applied. By the intermittent ponding method, a total of 360 cm
of water has been given, including 30 cm at each time. At the end of the
trial, the application of FIWGM has showed positive effect on the
physical and chemical properties of the soil. As the dose of FIWGM
increased, soil infiltration rates increased, and soil sodium and boron
concentrations decreased significantly. 360 cm of leaching water
provided the removal of exchangeable sodium equivalent to 33.7 and 42.9
tons of gypsum for 100 cm of soil depth, with 20 and 40 tons per hectare
of FWIGM applied to the test plots. The statistically significant
correlation coefficient (R2=0.921**) has been determined between the
leaching water depth (Dlw)/soil depth (Ds) and the boron/initial boron
remaining (B/Bo) in the soil (B/Bo = 0.622-0.168Ln Dlw/Ds)
