Radioisotope method of investigation of cultivated plants seeds arrangement in soil

Studies on the workability of precise seeders by means of labelling methods has been possible due to the solution of the following problems: labelling of seeds, radiation collimation of labelled seeds being sown, elaboration of measuring and registering systems as well as processing systems of a measuring signal. The developed method allows for precise, quick and full objective evaluation of the studied seeders to be done under natural conditions. (author)
