The relationship between soil test heavy metal values and the heavy metal uptake of plants were studied using soils from a long-term waste application experiment. Spring wheat, grass, spinach, lamb's lettuce and carrots were used as test plants to cover mono-and dicotyledons; vegetative and generative plant parts, and storage organs. Extractants compared included 0.1M CaCl2; 1M NH4NO3; 1M NH4-acetate; 0.025 M EDTA; DTPA; and 'aqua regis'. Results for CaCl2. DTPA and aqua regis are discussed.
