The presence of beneficial organisms for agriculture is important for maintaining the biological balance of the environment and therefore also for economic reasons.
Land of value to beneficial organisms are areas where they find adequate food, i.e. areas where nectar- and pollen-producing plant species grow, for example, as well as areas where they find safe places to live, breed and hide for the winter period. These conditions are met by habitats not used as arable land, where spontaneous vegetation develops, with many plant species attractive to beneficial insects. On farm, such land should be excluded from agricultural use in its entirety. A treatment that is recommended for baulk vegetation and marginal habitats next to drainage ditches, watercourses and on slopes is to mow the vegetation once a year, or several years, to prevent the development of woody plants and the encroachment of invasive species.
