“…This could be reason why in many cases lower NO 3 -N and TP concentrations were found in the CD system. The literature (Wesström and Messing, 2007;Ramoska et al, 2011;Povilaitis et al 2018) states that the controlled drainage reduced nutrients load while reducing drainage outflow. Controlled drainage outflow was 21-24% lower than the normally functioning drainage.…”

Lithuania remains one of the most extensively drained of the Baltic and Nordiccountries. The overall drained area (ditches plus tile drains) totalled 87% of theagricultural land area. Many nutrients from soil are leached through drainageresulting in polluting streams (drain flow receivers) water. Drain flow is treated asa major determinant of water quality. Therefore, the reduction of nutrients enteringthe drains is very important. Controlled drainage conception, when the outflowheight is increased at the mouth, helps reduce drainage runoff and partially purifywater. The aim of the research was to establish controlled drainage influence on thesoil moisture regime, nitrogen and phosphorus leaching. Investigations werecarried out in sandy loam and loam soils in the Middle Lithuanian Lowland. Basedon studies, several tendencies were observed: when drainage outflow began, theamount of soil moisture in subsoil (50-80 cm layer of the soil) of controlleddrainage plot was higher than in the conventional drainage plot, and highermoisture supplies stayed for a longer period of time. Controlled drainage had nodirect impact on phosphorus and nitrogen concentrations but they were influencedby the leaching quantities of plant usable nutrients. The reason that in many caseslower nitrate nitrogen (54% of all measurements) and phosphorus concentrations(77% of all measurements) were found in the conventional system rather than inthe controlled drainage might be connected to the fact that the latter area containedpredominantly lighter textured soils (sandy loam) making it easier to wash awaythe nutrients unused by plant.

“…Our challenge, which was the challenge of our predecessors and will likely be a challenge for our successors, is to achieve a balance between satisfying the need for a safe and abundant food supply while protecting natural resources. Povilaitis et al (2018) evaluated multiple strategies, including field and laboratory experiments, to investigate drainage effluent reductions of inorganic N and total P in Lithuania. Controlled drainage as an example of an in-field water management practice to reduce nutrient loss was compared with conventional drainage.…”

Abstract. This article introduces a special collection of fourteen articles accepted from among the 140 technical presentations, posters, and meeting papers presented at the 10th International ASABE Drainage Symposium. The symposium continued in the tradition of previous symposia that began in 1965 as a forum for presenting and assessing the progress of drainage research and implementation throughout the world. The articles in this collection address a wide range of topics grouped into five broad categories: (1) crop response, (2) design and management, (3) hydrology and scale, (4) modeling, and (5) water quality. The collection provides valuable information for scientists, engineers, planners, and others working on crop production, water quality, and water quantity issues affected by agricultural drainage. The collection also provides perspectives on the challenges of increasing agricultural production in a changing climate, with ever-greater attention to water quality and quantity concerns that will require integrated technical, economic, and social solutions. Keywords: ASABE Drainage Symposium, crop response, design and management, hydrology and scale, modeling, water quality.

“…Lithuania and Bosnia and Herzegovina (B&H) are considered as countries with high vulnerability and low adaptive capacity to cope with climate change (Easterling et al, 2000;Žurovec et al, 2017). The entire territory of these countries is characterized by the warming trend with positive trends in both the maximum and the minimum temperatures throughout the year (Radusin et al, 2013;Radusin et al, 2016;Merl, 2017;Popov et al, 2018;Povilaitis et al, 2018).…”

“…The average annual precipitation from 1977 to 2016 was 642 mm, or 1.4% higher than the climate normal (CN, defined as the three-decade 1981-2010 average) in Kaunas, Lithuania. The annual air temperatures in Kaunas for the 1977-2016 period (with an average of 7.0°C) showed increasingly variable patterns (Povilaitis et al, 2018). According to Trbic et al (2017) the entire territory of B&H is characterized by prominent and significant annual warming.…”

Lithuania and Bosnia and Herzegovina are considered as countries with high vulnerability and low adaptive capacity to cope with climate change. The entire territory of these countries is characterized by the warming trend, with positive trends in both the maximum and the minimum temperatures throughout the year. The increase in air temperature has resulted in change of evapotranspiration and mean annual water balance values. These countries are also frequently faced with an occurrence of severe droughts and heavy floods. The main purpose of this study was to determine and compare the severity of changes in mean annual water balance for two humid climatic zones, in order to understand how different areas of similar climate characteristics react to climate change and to analyze the significance of their influence. Monthly weather data from two weather stations, Kaunas (Lithuania) and Sarajevo (Bosnia and Herzegovina), for the time period of 30 years (1988 -2017) were used to determine and analyze the mean annual water balance. The results indicate that climate change has a different effect on the water balance of these two humid areas. Both locations showed a positive trend of reference evapotranspiration, with an increase of 1.450 mm year -1 to 1.503 mm year -1 . However, the total runoff and soil moisture deficit are decreasing in Kaunas (-0.480 mm and -2.114 mm year -1 , respectively), while they are increasing in Sarajevo (0.492 mm and 0.485 mm year -1 , respectively).
