As based on the analysis of 280 average soil samples gathered in eight state enterprises in the Iasi county, on about 35000 ha agricultural land, the authors have determined the content in mobile forms of boron, manganese, copper and zinc in the arable layer of the soil. It came out that the order of magnitude of the content is : MnCuZnB.Investigated soils are in their most part, poorly supplied in manganese (31.8%) and very few in cooper (12.1%). Finding out of deficiencies in micro-elements and using of micronutrient materials is recommended.
