Diagnosing and ameliorating problem soils

Most cropping paddocks in Western Australia have lower yielding areas within paddocks that perform poorly in most years. If the agronomy and management are good, the poor yields are usually due to soil-related problems. Some of these problems can be corrected or reduced by adopting certain proven practices. However, it is important to identify and quantify the problem so that decisions can be made on whether amelioration is possible and economically feasible.
