Question

Give four difference bw sandy n loamy soil

Answer 1

Sand does not hold water due to the fact that sandy soils have greater (and larger opening type) porosity. Sand particles (grain size) vary between 0.05 mm and 2 mm. Clay particles, on the other hand, are smaller than 0.002 mm. Although porosity of clay type soils is 45% (greater than that of sand (which is 34%)), specific yield of clay type soil is 3% (very low compared to that of sand (which is 25%)).

Specific yield is described as the volume of water that can actually be drained from an unconfined aquifer per unit of area per unit decline in the water table.

Conductivity (of water) in sandy soil is high (more than 40 m per day), whereas conductivity of clay is very low (0.4 cm per day).

Loam does not contain equal percentages of sand, silt, and clay. It exhibits approximately equal properties of these three.

Their adsorption mechanisms are different too.

Answer 2

Sandy loamy
1) large particles 1) small particles
2) holds less water 2) holds more water 3)holds water more time 3) for less time
4) this is rough soil 4) this is slippery soil
