Two experiment series were established in 2018 to quantify phosphorus and potassium cycling in WA cropping systems. The phosphorus cycling experiments ran for 4 years, and the design was a factorial of soil management, crop sequence and phosphorus application strategy. The potassium cycling experiments also ran for 4 years, and the design was a factorial of crop sequence and potassium application strategy. Grain yield was measured for each plot using a plot harvester.
Data is in Excel spreadsheet format.
