The authors selected 55 cultivated organic soils from nine areas in eastern Canada that represented important properties of the investigated population, in order to evolve useful tests for plant-available Cu, Fe, Mn, and Zn in the soils. As a first step, the level and distribution of the soil Cu into H/sub 2/O-sol, Ca-exchangeable, free-oxide-associated, weakly complexed, strongly complexed, strongly complexed, carbonate, and sulfide forms were determined by sequential extractions, and the influence of soil properties on the level and distribution of Cu was ascertained. The data revealed that the level of total Cu in the soils, ranging from 8.3 to 537.5 ..mu..g x g/sup -1/ was independent of soil pH; percentage of ash; pyrophosphate index; bulk density; cation exchange capacity; and level of Fe, Mn, and Zn. The Fe (0.15 to 3.57%) and Mn (32.5 to 916.8 ..mu..g x g/sup -1/) levels reflected the degree of decomposition and mineralization (percentage of ash: 6.0 to 53.7) of the organic soils, but Cu was mainly of external origin and thus increased with length of cultivation, due to the general practice of periodic applications of Cu.
