Place the letter or name(s) as applies in the appropriate space beside each soil property Clay and iron oxides eluviated so color (usually whitish or gray) is determined by sand and silt minerals. Dark-colored, thick High base saturation, soft even when dry Low base saturation, may be hard when dry 01 lluvial accumulation of silicate clay Wet at times, very high organic matter content. Nature of parent material altered by physical or chemical mean, no significant illuvial clay Thin, light-colored, low organic matter topsoil. . Surface horizon(s). Subsurface horizon(s). Diagnostic Horizons: a. Mollic b. Umbric c. Cambic d. Ochric e. Argillic f. Natric g. Oxic h. Histic i. Albic 5. Place the correct Soil Temperature Regime in the space below each set of data below Tempera O N EmaiWord Save 54 56 68 67588278Explanation / Answer
MOLLIC- .surface horizon
these types are soil found in semi-arid to semi-humid areas, they are highly fertile in nature.
Umbric - dark colored thick
these are thick dark colored soil horizon. it has ph less than 5.5 means it indicate acidic soil
Cambic- clay and iron eluviated soo color is determined by sand and silt mineral
ochric- thin low organic topsoil
surface horizon lacking fine stratification and which is either light coloured or thin or low organic content . it may hard when dry.
argillic - illuvial accumulation of silicate clay
as the name suggest the argillic means rich in clay matter which is silicate nature.
natric - subsurface soil
it is similar to argillic soil but always in subsurface
oxic soil - surface horizon
oxic soil horizon must be rich in clay 40percent, more than 30cm thick sandy loam texture, less than 10percent weathered mineral.
histic soil -wet at time high organic content
saturated with water most of the time
albic soil - nature of parent mineral altered by physical or chemical mean
