Soils provide plants with essential minerals and nutrients. Soils provide air for gaseous exchange between roots and atmosphere. Soils protect plants from erosion and another destructive physical, biological and chemical activity. Soils hold water (moisture) and maintain adequate aeration.
What are the situations leading to the loss of top soil?
Soil compaction, low organic matter, loss of soil structure, poor internal drainage, salinisation and soil acidity problems are other serious soil degradation conditions that can accelerate the soil erosion process. This Factsheet looks at the causes and effects of water, wind and tillage erosion on agricultural land.

What is the pH of topsoil?
The pH level is the way in which we measure the acidity or alkalinity of our topsoil. pH levels start at 7 – which is neutral, this is neither acid nor alkaline.
