Abstract

An appropriate amount of soil was picked up from the surface horizon (0-30 cm) from the rangeland of Darab city. After air drying and passing through a 2 mm sieve, some physical and chemical properties of the soil were measured. A factorial pot experiment was conducted in a completely randomized design with four replications. The first factor includes biochars in 7 levels (no application of biochar (C), wheat biochar (1.5 % w/w) (GB1), wheat biochar (3 % w/w) (GB2), corn biochar (1.5 % w/w) (ZB1), corn biochar (3 % w/w) (ZB2), cotton biochars (1.5 % and 3% w/w) and the second factor includes the use of lead (Pb) at 3 levels (0 (Pb0), 150 (Pb150) and 300 (Pb300) mg kg-1 soil) under forage panicum cultivation. After copmpleting vegetative growth, the plants were cutted and harvested from 0.5 cm of the soil surface. This study indicated that with increasing the biochar levels from 0 to 3 % (w/w), the electrical conductivity (0.31, 0.15 and 0.02 dS/m), soil organic carbon (53, 59 and 63%) and soil pH (0.13, 0.05 and 0.15 units) were increased and the Pb availabity (16.12, 12.83 and 10.25%) was decreased, respectively. With enhancing the Pb levels from 0 to 300 mg kg-1 soil, the concentration of soil manganese (17.27%) and potassium (4.54%) availability were significantly reduced.
