Effects of soil bulk density on soil water-holding capacity were explored through simulated experiments designed to have soils different in soil texture by artificially altering composition of soil particle fractions. (1) Water holding capacity and specific water capacity of the experimental soils decreased along with increasing soil bulk density. (2) Soil saturated water content, field moisture capacity and wilting coefficient showed the same trend, and negative correlation of power, exponent and exponential function, respectively, with soil bulk density. (3)Soil available water, readily available water and slowly available water contents were also significantly affected. The three water parameters decreased along with increasing soil bulk density, too, showing negative correlation of exponential, power and logarithmic function, respectively, with soil bulk density.
