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.

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.
