Sand can be used for increasing water intake capacity and reduce dispersion
ratio in a Vertisol. A study was conducted at Bellary, India with amended soil
with 12 sand and soil mixtures ranging from 0:1 to 1:1 ratio on weight basis. The
analysis indicated significant decrease of available water; plastic and liquid
limits; dispersion ratio; available N, P and K; and increase in bulk density with
increase of sand in mixture. The increase in hydraulic conductivity was below
1.0 cm/hr upto 0.4:1 ratio and increased significantly to 3.63 cm/hr with
increase in sand. The changes were assessed based on a regression model of soil
and sand ratios. Each parameter was assessed using weighted scores based on
linear scoring method. The sum of scores indicated that 0.4:1 of sand and soil
was superior for different parameters. The ratio was also superior for retaining
soil moisture for a longer period inVertisols.
