Abstract

This paper presented development, calibration and testing steps of a device to collect soil penetration resistance data. This device can be hitched to the tractor through three point hitch system for data collection. The developed device consisted of hydraulic cylinder, open center hydraulic system, electrical control panel, hydraulic hoses, frame with three-point hitch and measuring staffs. At the end of hydraulic cylinder, different parts could be attached for collecting soil properties data. The cone tip is designed as ASAE standard which will provide cone index values with depth. Verification tests for cone index values using locally made hammer penetrometer and commercially static penetrometer were correlated quite well. The developed device seemed to be easy to use in the field as a static penetrometer. Also, constant rate of pushing shaft in the soil will be obtained and this will lead to good accuracy. The collected data were statistically analyzed to find out the effect of site, location, penetration depth and their interactions on the penetration resistances obtained by the three different devices. Also, the significant difference among penetration resistances was estimated by the three different devices (whole data, 56 points were compared by F- test at 1% probability level). The resistance to penetration results showed distinct behaviors for the studied depths, sites and location inside each site indicating the importance of measuring penetration resistances in different location in the experimental field at specified depth due to spatial variations. The mathematical model for soils under study to get penetration resistance was:              R2 = 0.732 where Y is soil penetration  by developed device (Mpa),  X1 is depth in the range of   5-30 cm, X2 is soil moisture content in the range of 8.14-33.59 % (db), X3 is soil bulk density in the range of 1.03-1.46 g/cm3 and  X4 is soil texture index in the range of 0.665-0.716.
