This thesis on the theme Possibilities dried grained dung utilization and other organic dungs in nursery production was elaborated in phase 2006 -- 2008 in The Department of Breeding and Propagation of Horticultural Plants on Mendel University of Agriculture and Forestry in Brno. Using of organic dungs is necessary at rising soil fertility because the main component of these dungs form organic materials of vegetable and animal origin. Their main advantage is their rise and regeneration of humus support and positive action on soil structure, water and air mode in soil. Their disadvantage is their big volume and due to that the recommended doses for plant fortilization are too high. We can use, as alternative this disadvantage in comparision with mineral dungs, grained organic materials. Granules are dried to low volume mass and they have higher content of nutrients. This form facilitates not only their aplication ,but also manipulation with them. The organic dungs are necessary component of fortilization, how it results from cited experiment, not only for their nutrition quality and contnent humus materials, that have specifically effect to plant grow and progress, but also for their ability to give support to better utilization of nutrients from industry dungs. Dosage depends on demands for individual plants. Here is one parameter, that is impossible omit in the first place at containered plants, and that is possible plant damage by lack of water. The producers emphasise importance of watering because water is utilized for dried dungs dissociation. Single-shot utilization of high batch can to cause other damage. We can predate to these dangers by help of automated watering and single batch of dungs partition. Dictum on dungs utilization will always stay on growers.
