Methodology for use of technological waters on agricultural land (3rd ed.)
Mühlbachová, Gabriela ; Svoboda, Pavel ; Klír, Jan ; Vegricht, Jiří
The production of technological waters from stables is evaluated in the methodology for the use of technological waters in agriculture. The corresponding legislation amended in 2021 is described. Attention is focused on technological waters from livestock breeding and simple processing of plant products. The production of technological waters is evaluated from the point of view of individual operations in which the technological waters are produces, particularly in milking and cooling equipment. THe characteristics of technological waters, particuarly the nutrient contents and potential risks of their use on the agricultural land are also evaluated in the methodology. the influence of tehcnological eaters on the growth of plants and microbial biomass content and activity in the soil was experimentally verified. The methodology contains the recommendation for the application of technological waters on the agricultural land.

Benefits and risks of nitrogen fertilizers for support of straw decomposition
Mühlbachová, Gabriela ; Růžek, Pavel ; Kusá, Helena ; Vavera, Radek ; Káš, Martin ; Watzlová, Elizaveta
The methodology evaluates the benefits and risks of generally used nitrogen application to support cereal straw decomposition. The possibilities of reduction of the commonly recommended nitrogen doses were verified. The appropriate fertilization manners are suggested with regard to nutrient availability for following crops including optimal N doses in cases when the N supply is necessary. The recommendations represent the result of field trials in different soil-climatic conditions and also on farms, where different nitrogen fertilizers have been applied to winter wheat straw. The results showed that depending on the weather, the fertilization with nitrogen in the summer and autumn period decomposes 30-50% of the straw in the given year, and without fertilizing then 25-30%. Based on the obtained results, there is recommended to reduce fertilization with nitrogen mineral fertilizers to 4-5 kg N/t of straw If the following crop id the oilseed rape or intercrop with higher nitrogen nutrition demands, there is possible to increase N dose to 6-10 kg N/t straw. This recommendation is related also on liquid manure and organic fertilizers containing nitrogen also in organic form. Lower doses of above mentioned range are recommended if no following crop is sown, higher does if possible to apply before sowing of winter crops or intercrops. Overall straw decomposition was higher after application of fertilizers on straw leaved 3 weeks on soil surface. Straw on soil surface reduces water losses from soil and warming in warm summer period, which improves water, carbon and nutrient retention in a soil.

The methodology proposes criteria for determination of the content of micro-nutrients in soils and their evaluation via useing of the extraction method Mehlich 3: certified methodology for practice
Čermák, Pavel ; Mühlbachová, Gabriela ; Káš, Martin ; Vavera, Radek ; Pechová, Miroslava
The methodology proposes criteria for determination of the content of micro-nutrients in soils and their evaluation via useing of the extraction method Mehlich 3. Extraction procedure Mehlich 3 is the official analytical method currently used in testing system of agricultural soils for the determination of the content of available P, K, Mg and Ca. There are criteria for valuation of content of these available nutrients - see Decree No. 275/1998 Coll., on Agrochemical Testing of Agricultural Soil and Land Surveys of Forest Lands, as amended). The existing criteria for above mentioned nutrients are due to this methodology extended by next five elements (Cu, Fe, Mn, Zn and B), marked in field of plant nutrition as micro-nutrients. The simple and easy Mehlich 3 analytical procedure applicable to a variety of different elements, is already used in a wide range of laboratories, allows to extend the criteria for the others elements. In addition, many laboratories can use the multi-elementar analytical instruments ICP-OES. Suggested criteria will also serve for farmers for valuation of soil supply by micro-elements.

Methodological guidance for management in vulnerable zones: 2nd edition; Certified methodology
Klír, Jan ; Kozlovská, Lada ; Haberle, Jan ; Mühlbachová, Gabriela
The methodology describes measures for protection of waters against pollution caused by nitrates from agricultural sources in vulnerable zones of the Czech Republic. The methodology clearly describes individual requirements of the 4th Action Programme of the Nitrates Directive for the period 2016–2020 as ratified by CR government for reduction of nitrogen losses by nitrates leaching into surface water and groundwater, reduction of surface water eutrophication and reduction of nitrates transmission to the neighboring countries in waters flowing from the territory of the Czech Republic. The aim is to reduce water pollution by nitrogen compounds from agricultural sources into the aquatic environment, the results of which are such as to cause hazards to human health, harm to living resources and to aquatic ecosystems, damage to amenities or interference with other legitimate uses of water. The publication also includes links to selected technical publications and related legislation. The second updated edition responds to amendment to the Government Regulation No. 262/2012 Coll., On determining the vulnerable areas and action programme, issued in 2018 as No. 27/2018 Coll.

The methodology describes measures for protection of waters against pollution caused by nitrates from agricultural sources in vulnerable zones of the Czech Republic. The methodology clearly describes individual requirements of the 4th Action Programme of the Nitrates Directive for the period 2016–2020 as adapted by CR government for reduction of nitrogen losses by nitrates leaching into surface water and groundwater, reduction of surface water eutrophication and reduction of nitrates transmission to the neighboring countries in waters flowing from the territory of the Czech Republic. The aim is to reduce water pollution from nitrogen compounds from agricultural sources into the aquatic environment, the results of which are such as to cause hazards to human health, harm to living resources and to aquatic ecosystems, damage to amenities or interference with other legitimate uses of water.
