Biotesting as a method of environmental research is characterized by a comprehensive approach, efficiency and effectiveness. The results of determining the phytotoxicity of three different complex composts whch composed of livestock and chemical industry wastes (cattle manure and phosphogypsum) are presented in the article. Corn is selected as a test object. Significant differences between the options identified in the experiment. Composts do not adversely affect the development of plant seedlings. A favorable compost ratio has been identified.
