The Balance of the Nitrogen in Agriculture
Klír, Jan ; Beranová, Jana ; Dědina, Martin ; Wollnerová, Jana
Methodology addressing nitrogen balance issues is a suitable tool for verifying the correctness of agricultural management and shows the relation between nitrogen used in agriculture and its losses in gaseous form to air or in the form of nitrates to surface and groundwater. The assessment of nitrogen balance, greenhouse gas emissions and pollutants is closely linked and therefore requires the quantification of nitrogen sources used in agriculture. Synchronization of input data used to evaluate nitrogen flows in agriculture is essential to increasing the methodological level of reporting the nitrogen balance, greenhouse gas emissions and pollutants for the Czech Republic in terms of the requirements of international organizations.

Farming practices for efficient use of nitrogen and reduction of its losses: Certified methodology for practice
Klír, Jan ; Haberle, Jan ; Růžek, Pavel ; Šimon, Tomáš ; Svoboda, Pavel
The methodology describes the main risks of nitrogen losses and recommended practices for their reduction. Practically applicable methods for the evaluation of the nitrate leaching risk depending on the soil, crop, root range, croping system, irrigation and weather conditions are described in detail. Consequently, suitable soil treatments and fertilization are proposed to improve the utilization of the nitrogen and uniformity of the water soaking.

Methodology for use of technological waters on agricultural land: 2nd edition; Certified methodology for practice
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 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 produced, particularly in milking and cooling equipment. The characteristics of technological waters, particularly the nutrient contents and potential risks of their use on the agricultural land are also evaluated in the methodology. The influence of technological waters 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.

The methodology of the proper way of manure storing on agricultural land: 2nd edition; Certified methodology for practice
Svoboda, Pavel ; Wollnerová, Jana ; Kozlovská, Lada ; Klír, Jan
The proposed methodology describes a complete manual to the correct storage of farmyard manure on agricultural land before its application. Special attention is paid to measures for storage of farmyard manure in vulnerable zones identified in the action program of the Nitrates Directive. For selecting a suitable place to storing farmyard manure are available in the methodology detailed instructions, with the help of data in the registry of soil LPIS at web site Portál farmáře. The model of the required emergency plan or supplement of the plan is also given in the methodology. The second updated edition responds to changes in legislation in 2016, in particular the amendment to the Government Regulation no. 262/2012 Coll., On determining the vulnerable areas and Action Programme, which was issued under No. 235/2016 Coll.

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.

Management principles for waters protection against pollution by nitrates
Klír, Jan ; Kozlovská, Lada
The methodology summarizes the codes of good agricultural practices for protection of waters against pollution caused by nitrates from agricultural sources. The requirements contributing to reduction of nitrogen losses as exclusion of nitrogen fertilization during unsuitable periods, on flooded, frozen or snow covered soils are concisely described. Further, the recommendations for management of sloping fields, in proximity of surface waters and the principles of fertilizer use respecting soil-climate conditions, nitrogen demand by crops and soil nutritional status are given. Explanation of basic technical terms and references of relevant publications and legislative norms are supplied.
