Soil constraints are any soil physical or chemical characteristics that limit agricultural productivity. In some cases, there are practical and profitable management options to reduce the constraint, leading to improved yields and profitability. Constraints may include acidic topsoil, sub-soil compaction, water repellence, saline groundwater and soils, and wind and water erosion. Recognising soil constraints and their potential impact on agricultural systems is difficult, but very important. The Department of Agriculture and Food, Western Australia can provide the technical information needed for landholders to understand the condition and properties of their soils, and develop management strategies to maintain and improve soil condition.
