PENGARUH KANDUNGAN AIR TERHADAP KEGEMBURAN TANAH
ABSTRACT: The research was
conducted based on the fact that is still to the number of ascription to less
impotent it friability and soil tilt to prepare medium growth of crop. The aim
of this research was to find out the effect of water content to soil friability
and determine correct water content to soil tilt.
The location of
the experiment was
at Laboratory of
Agricultural Power and Machinery, Agricultural
Engineering Department, Faculty
of Agricultural Technology, Brawijaya University,
Malang in June –
July
2002. The parameter
was decided by measuring compression strength of soil on
various soil volumes and soil water contents. This soil sample was taken from Balai Benih
Induk Palawija, Bedali, Lawang, Malang Regency.
The result of those experiments indicated that effect of moisture content
of soil on strength of soil was significant and there was interaction between
soil moisture content and volume of soil aggregate. The reduction of volume of soil aggregate
with decreasing of soil moisture content
caused an increasing
of soil strength.
The value of
soil strength ranged from 7.19
kPa to 166.39 kPa. The friability of Bedali soil was get at the ranged of soil
moisture content from 20 % to 26 %, with soil friability index (k): 0.25 0-
0.27.
Keyword: soil friability, soil
moisture content, volume of soil aggregate
