K. Welsh, Soil TLC (48277-30) Various types of soil were ground and sieved and that fraction of 262 micron size was saved for TLC studies (42669-42). An intimate mixture of 150 g of 262 micron size greenhouse soil (sandy loam) with 80 ml of water was well slurried and spread onto 10 x 20 cm glass plates using an in-house designed spreader (designed by J. W. Belisle, A. Mendel, and G. Guthrie). The plates were allowed to air dry. A plate was spotted 2 cm from the bottom with radiolabeled-FC-95,-FC-143, and-FM 3422. The samples were those used earlier for water solubility studies. The plate was air-dried and developed 100 mm from the original TSpLoCtdeinveltohepinagscetnandkingpremvodieouswlityhewqautielribriantead fwiilttherwaptaeprer-[1oirneonde day.
