In mining and quarrying, carried out surface (whoesale quarry) technologies with large scale devastation of cultural landscape, the equilibrium of the natural ecosystem and also to move and store large amounts of soil material skrývaného. The mining work should be completed by the successful rehabilitation and restoration of land reclaimed their original purpose. The aim is to evaluate the current development of forestry reclamation in the Sokolov coal basin, perform the calculation and assessment of the individual methods of forestry land reclamation, hit siege works. Perform the economic evaluation of the effectiveness of forestry reclamation and evaluated to determine the economic efficiency of forestry reclamation. According to a growing economic results were evaluated forests these species: sessile oak, oak, spruce and larch on dumps William and Big Riesl. By comparing the results obtained using the above procedures was found, when calculating income from timber production unprofitable forestry reclamation projects, but after the inclusion of other functions of forests calculation results were positive in all cases. As the most effective based sessile oak stands, followed by stands of spruce and oak summer.

The aim of the thesis was to assess the effect of long-term application of different doses of nitrogen with phosphorus and potassium on proportion of agrobotanical groups, on forage quality and yield of the grasslands vegetation of the type Arrhenatherion elatioris. Longterm experiment is located near the village of Senožaty (Pelhřimov). This is mesophilous meadow with a predominance of Arrhenatherum elatius. An experiment in the form of random sample of blocks includes six varieties of fertilization: unfertilized control, PK, N50PK, N100PK, N150PK and N200PK. Evaluation of the botanical composition, forage quality and yields of meadow fodder was carried out in the 1st cut, the 2nd cut and the 3rd cut. Composition of grass, legumes and other dicots plants was evaluated by weight method. Qualitative parameters of the forage (crude protein, crude fiber, PDIE and organic matter digestibility) were evaluated by NIR spectroscopy. The results show that yield of aboveground biomass in the first cut has been twice bigger on plots of nitrogen fertilization than unfertilized control. Variants N50PK to N200PK contained 90 % of grasses, lower than 2 % legumes and lower than 6 % other herbs. Content of crude protein and crude fiber was increased with increasing dose of nitrogen applied. In first cut was highest organic matter digestibility in variants N100PK in comparison with other variants. Yield of dry matter aboveground biomass was half in the second cut compared with the first. On variants N100PK to N200PK was high proportion of grasses and very low proportion of legumes and other herbs. In the second mowing, the highest content of crude protein have been find out in biomass of unfertilized control. The crude fiber content increased with the intensity of fertilization. In the third cut, yield of dry matter biomass was very low, but content of crude protein and PDIE was high. In dry matter biomass in third mowing, content of crude fiber was lowest and organic matter digestibility was highest. Significant correlation between the proportion of individual agrobotanical groups and forage quality were found only in the fiber content of the 1st and 2nd cut and PDIE in forage 3rd cut. The results of the thesis show that the forage quality, yield of dry biomass and botanical composition of grassland type Arrhenatherion elatioris is most appropriate fertilize 50 kg N.ha-1 with phosphorus and potassium.

The main factors affecting the yield and the quality of grassland are nutrient availability and water regime. In nature and of course in agriculture, water is the most important factor influencing plant growth and reproduction. The aim of this thesis was to evaluate the effect of water regime on germination of selected grass species. We have focused on the following grass species, suitable for use in energy: Dactylis glomerata L. Padánia cultivar, Phalaroides arundinacea L., Chrastava cultivar and Agropyron elongatum L. Under water stress condition, the highest germination rate of 69 % was observed in Agropyron elongatum L., followed by Dactylis glomerata L. (54, 6 %). The lowest germination rate of 28, 6 % was recorded in Phalaroides arundinacea L. This study also compares dry matter yields of selected species during spring harvest. Average yield was 3,3 t.ha-1 in the first year. This work is based on authors own measurement and on the information obtained from Czech hydrometeorological institute.

Fodder from lasting grass growths serves from 80% to fed ruminants. Therefore is setting high emphasis on quality fodder from trifolium, grass and trifolium-grass growths. On this account fit itrodukcion try in these growths imply at full blast useful kinds plants (trifolium), which have improving effects on fodder. Once of these improving products is also Lathyrus pratensis. His introduction increases substitution legumin in lasting meadow growths and share rhizobial nitrogen on production knows - nose fodder and nutritive valuable degestible nitrogen factory materials. Occurrence Lathyrus pratensis is impressed with type herbal growth and his differential management.
