Evaluates seed quality utilizing specialized testing procedures including ultraviolet light(fluorescence) testing of Ryegrass and other grasses, hydrochloric acid testing to separate Brassica species, ferric acid testing for mechanical damage in legumes, sodium hydroxide analysis for wheat mixes, phenol test in wheat and Kentucky Bluegrass identification and vigor tests to predict field performance;

Tests seed samples for purity, sod quality, compliance with the annual bluegrass quarantine, varietal purity (Kentucky Bluegrass) and compliance with phytosanitary regulations; operates seed dividers, analytical balances, seed blowers and other equipment used in making purity analyses; separates samples for purity analysis into pure seeds, inert matter, other crop seed and weed seed; identifies seed contaminates in the sample as to genus and species and records number per pound of sample; identifies, weighs and computes percentages of impurities; identifies varieties of weed seed; separates seed of the same genus by varieties of weed seed; separates seed of the same genus by species and/or variety; applies appropriate certification and/or analytic procedures including the Federal Seed Act requirements and Association of Official Seed Analyst (AOSA),International Seed Testing Association (ISTA), Canadian and Organization of Economic Cooperative Development/European Economic Community (OECD/EEC) rules for seed testing;
