AB  - From 1968 Broadbalk was divided into 10 sections. Wheat grain and straw from selected sections and plots were collected each year and analysed for macronutrient content: Nitrogen (N) each year, phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and sodium (Na) all years except 1976-1985 and sulphur (S) from 1996.  Data is presented as % nutrient in grain and straw and is the response to different fertiliser treatments and cropping. The sample preparation, digestion methods and analytical instruments changed with time, but results over time are generally comparable.
