Explanation:
Detailed explanation-1: -Iron found within the soil is oxidised more readily due to the higher oxygen content. This causes the soil to develop a ‘rusty’ colour. The colour can be darker due to organic matter. These soils often have poorer drainage than red soils.
Detailed explanation-2: -Top soil is dark in colour due to the presence of humus and dead and decaying organic matter.
Detailed explanation-3: -Generally speaking, colors that indicate good soil are dark brown, red and tan. Dark brown suggests that the soil has a good percentage of organic matter. Red reflects the oxidized iron content of the soil, while tan indicates a combination of organic matter and iron.
