Phosphate for raining



Texture and colour of rainy day soil

The colour of the raining day soil is alot darker and has a rough, crumbly texture which seperates each grain.

texture and colour of soil for sunny day

The colour of the soil is a lightish brown with a rough grainy, sandy feel

Possible parent rock for both rainy and sunny day

The possible parent rock for both raining soil and sunny soil is Sandstone as most of Sydney's base is sandstone, the moisture level for both was relatively low also suggesting that the soil was sandy and easily drained common for a base of sandstone.
